== History ==
[[File:Illustration of contemporary and past human populations Our World in Data.png|thumb|Comparison of humans living today with all previous generations]]
Historical migration of human populations begins with the movement of ''[[Homo erectus]]'' out of Africa across [[Eurasia]] about a million years ago. ''[[Human|Homo sapiens]]'' appear to have occupied all of Africa about 300,000 years ago, moved out of Africa 50,000 – 60,000 years ago, and had spread across [[Prehistory of Australia|Australia]], [[History of Asia|Asia]] and [[Paleolithic Europe|Europe]] by 30,000 years BC. [[Models of migration to the New World|Migration to the Americas]] took place 20,000 to 15,000 years ago, and by 2,000 years ago, most of the [[Pacific Islands]] were colonized.
Until c. 10,000 years ago, humans lived as [[hunter-gatherer]]s. They generally lived in small nomadic groups known as [[band societies]]. The advent of agriculture prompted the [[Neolithic Revolution]], when access to food surplus led to the formation of permanent [[human settlement]]s. About 6,000 years ago, the first proto-states developed in [[Mesopotamia]], [[Egypt]]'s [[Nile Valley]] and the [[Indus Valley civilisation|Indus Valley]]. Early human settlements were dependent on proximity to [[water resources|water]] and, depending on the [[lifestyle (sociology)|lifestyle]], other [[natural resources]] used for [[subsistence economy|subsistence]]. But humans have a great capacity for altering their [[habitat (ecology)|habitats]] by means of technology.
Since 1800, the [[human population]] has increased from one billion<ref>{{cite news | url = http://news.bbc.co.uk/1/hi/sci/tech/411162.stm | access-date = 5 February 2008 | work=BBC News | title=World's population reaches six billion | date=5 August 1999}}</ref> to nearly eight billion,<ref name=7billpop>{{cite web|title=UN population estimates.|url=http://esa.un.org/unpd/wpp/unpp/p2k0data.asp|work=Population Division, United Nations|access-date=4 July 2013}}</ref> In 2004, some 2.5 billion out of 6.3 billion people (39.7%) lived in [[urban area]]s.

== Religion ==
{{Further|List of religious populations}}
[[File:Prevailing world religions map.png|thumb|upright=1.25|Major denominations and religions of the world]]
The table below lists religions classified by philosophy; however, religious philosophy is not always the determining factor in local practice. Please note that this table includes heterodox movements as adherents to their larger philosophical category, although this may be disputed by others within that category. For example, [[Caodaism|Cao Đài]] is listed because it claims to be a separate category from Buddhism, while [[Hòa Hảo]] is not, even though they are similar [[new religious movement]]s.
The population numbers below are computed by a combination of census reports, random surveys (in countries where religion data is not collected in census, for example United States or France), and self-reported attendance numbers, but results can vary widely depending on the way questions are phrased, the definitions of religion used and the bias of the agencies or organizations conducting the survey. Informal or unorganized religions are especially difficult to count. Some organizations may wildly inflate their numbers.

Since the late 19th century, the demographics of religion have changed a great deal. Some [[Western culture|countries with a historically large Christian population]] have experienced a significant decline in the numbers of professed active Christians: see [[demographics of atheism]]. Symptoms of the decline in active participation in Christian religious life include declining recruitment for the [[priest]]hood and [[monastery|monastic life]], as well as diminishing [[Church attendance|attendance at church]]. On the other hand, since the 19th century, large areas of [[sub-Saharan Africa]] have been converted to Christianity, and this area of the world has the highest population growth rate. In the realm of [[Western culture|Western civilization]], there has been an increase in the number of people who identify themselves as [[secular humanism|secular humanists]]. Despite the decline, [[Christianity]] remains the dominant religion in the [[Western world]], where 70% of the population is Christian.<ref name="Global Christianity">{{cite web|author=Analysis |url=http://www.pewforum.org/Christian/Global-Christianity-exec.aspx |title=Global Christianity |publisher=Pew Research Center |date=19 December 2011 |access-date=17 August 2012}}</ref> In many countries, such as the People's Republic of China, communist governments have discouraged religion, making it difficult to count the actual number of believers. However, after the collapse of communism in numerous countries of Eastern Europe and the former [[Soviet Union]], religious life has been experiencing resurgence there, in the form of traditional [[Eastern Christianity]].<ref name="Pew Research Center1">{{Cite web|url=https://www.pewforum.org/2018/10/29/eastern-and-western-europeans-differ-on-importance-of-religion-views-of-minorities-and-key-social-issues/|title=Eastern and Western Europeans Differ on Importance of Religion, Views of Minorities, and Key Social Issues|work=Pew Research Center|date=October 29, 2018}}</ref> While, Islam however has gained considerably in the Soviet Unions former republics in [[Central Asia]].

Birth rates vary even within the same geographic areas. In Europe, as of July 2011, Ireland's birth rate is 16.5 percent, which is 3.5 percent higher than the next-ranked country, the UK. France has a birth rate of 12.8 per cent while Sweden is at 12.3 percent.<ref>{{cite web|url=http://www.thejournal.ie/ireland-has-one-of-highest-birth-and-lowest-death-rates-in-eu-189080-Jul2011/ |title=Ireland has one of highest birth and lowest death rates in EU |work=Thejournal.ie |date=29 July 2011 |access-date=6 September 2018}}</ref> In July 2011, the UK's Office for National Statistics (ONS) announced a 2.4% increase in live births in the UK in 2010 alone.<ref name="guardian1">{{cite news |url=https://www.theguardian.com/society/2011/jul/13/more-midwives-birth-rate-40-year-high |title=Call for more midwives as birth rate reaches 40-year high |work=The Guardian |date=13 July 2011 |access-date=6 September 2018}}</ref> This is the highest birth rate in the UK in 40 years.<ref name="guardian1"/> By contrast, the birth rate in Germany is only 8.3 per 1,000, which is so low that both the UK and France, which have significantly smaller populations, produced more births in 2010.<ref>{{cite news |url=http://www.irishtimes.com/newspaper/health/2011/0809/1224302081071.html |title=Germany faces up to its kinder surprise |newspaper=The Irish Times |date=9 June 2018 |access-date=6 September 2018}}</ref> Birth rates also vary within the same geographic area, based on different demographic groups. For example, in April 2011, the U.S. CDC announced that the birth rate for women over the age of 40 in the U.S. rose between 2007 and 2009, while it fell among every other age group during the same time span.<ref>{{cite news |url=http://www.cnn.com/2011/HEALTH/04/01/cdc.births.decline/index.html |title=CDC records rise in birth rate for women over 40 |work=CNN.com |access-date=6 September 2018}}</ref> In August 2011, Taiwan's government announced that its birth rate declined in the previous year, despite the fact that it implemented a host of approaches to encourage its citizens to have babies.<ref>{{cite news |url=https://www.bbc.co.uk/news/world-asia-pacific-14525525 |title=Taiwanese birth rate plummets despite measures |work=BBC News |access-date=6 September 2018}}</ref>
Birth rates ranging from 10 to 20 births per 1000 are considered low, while rates from 40 to 50 births per 1000 are considered high. There are problems associated with both an extremely high birth rate and an extremely low birth rate. High birth rates can cause stress on the government welfare and family programs to support a youthful population. Additional problems faced by a country with a high birth rate include educating a growing number of children, creating jobs for these children when they enter the workforce, and dealing with the environmental effects that a large population can produce. Low birth rates can put stress on the government to provide adequate senior welfare systems and also the stress on families to support the elders themselves. There will be less children or working age population to support the constantly growing aging population.
The ten countries with the highest and lowest crude birth rate, according to the 2018 and 2022 [[The World Factbook|CIA World Factbook]] estimates, are:<ref>{{cite web |title=Birth rate - The World Factbook |url=https://www.cia.gov/the-world-factbook/field/birth-rate/ |website=www.cia.gov |access-date=25 July 2022}}</ref>

See [[list of countries by mortality rate]] for worldwide statistics.
According to the [[World Health Organization]], the 10 leading [[causes of death]] in 2002 were:
<!-- ref: http://www.who.int/entity/whr/2004/annex/topic/en/annex_2_en.pdf -->
# 12.6% [[Ischemic heart disease]]
# 9.7% [[Cerebrovascular disease]]
# 6.8% [[Lower respiratory infection]]s
# 4.9% [[HIV/AIDS]]
# 4.8% [[Chronic obstructive pulmonary disease]]
# 3.2% [[Diarrhoeal disease]]s
# 2.7% [[Tuberculosis]]
# 2.2% [[Trachea/bronchus/lung cancers]]
# 2.2% [[Malaria]]
# 2.1% [[Road traffic accidents]]
Causes of death vary greatly between first and third world countries.
According to [[Jean Ziegler]] (the [[United Nations]] Special Rapporteur on the Right to Food for 2000 to March 2008), mortality due to [[malnutrition]] accounted for 58% of the total mortality in 2006: "In the world, approximately 62 millions people, all causes of death combined, die each year. In 2006, more than 36 millions died of hunger or diseases due to deficiencies in [[micronutrients]]".<ref name=Ziegler>[[Jean Ziegler]], ''[[L'Empire de la honte]]'', Fayard, 2007 {{ISBN|978-2-253-12115-2}}, p.130.</ref>
Of the roughly 150,000 people who died each day across the globe, about two-thirds—100,000 per day—died of age-related causes in 2001, according to an article which counts all deaths "due to causes that kill hardly anyone under the age of 40" as age-related.<ref name="doi10.2202/1941-6008.1011">{{cite journal | last = Aubrey D.N.J | first = de Grey | author-link = Aubrey de Grey | title = Life Span Extension Research and Public Debate: Societal Considerations | journal = Studies in Ethics, Law, and Technology | volume = 1 | issue = 1, Article 5 | year = 2007 | url = http://www.sens.org/files/pdf/ENHANCE-PP.pdf | doi = 10.2202/1941-6008.1011 | access-date = 7 August 2011 | citeseerx = 10.1.1.395.745 | s2cid = 201101995 | archive-url = https://web.archive.org/web/20161013163622/http://www.sens.org/files/pdf/ENHANCE-PP.pdf | archive-date = 13 October 2016 | url-status = dead }}</ref>{{better source needed|| reference uses an extremely broad definition of "age-related" deaths, including even traffic accidents due to poor eyesight|date=June 2018}} In industrialized nations, the proportion was even higher according to that article, reaching 90%.<ref name="doi10.2202/1941-6008.1011"/>
== Total fertility rate ==
{{See also|List of sovereign states and dependencies by total fertility rate}}
The [[Total fertility rate]] is the average number of children born per mother. In 2021, fertility levels high were found in sub-Saharan Africa (4.6 births per woman), Oceania excluding Australia and New Zealand (3.1), Northern Africa and Western Asia
(2.8), and Central and Southern Asia (2.3).<ref name="unorgde"/>
There is an inverse correlation between [[income and fertility]], wherein [[Developed country|developed countries]] usually have a much lower [[fertility rate]]. Various [[fertility factor (demography)|fertility factors]] may be involved, such as education and urbanization. [[Mortality rate]]s are low, [[birth control]] is understood and easily accessible, and costs are often deemed very high because of education, clothing, feeding, and social amenities. With wealth, contraception becomes affordable. However, in countries like Iran where contraception was made artificially affordable before the economy accelerated, birth rate also rapidly declined. Further, longer periods of time spent getting higher education often mean women have children later in life.<ref>{{Cite news|last=Gallagher|first=James|date=15 July 2020|title='Jaw-dropping' world fertility rate crash expected|language=en-GB|work=BBC News|url=https://www.bbc.com/news/health-53409521|access-date=18 July 2020}}</ref> Female labor participation rate also has substantial negative impact on fertility. However, this effect is neutralized among Nordic or liberalist countries.<ref>{{Cite web |url=http://homepage3.nifty.com/sociology/motion.html |title=Graph Charts of TFR and FLR using Google Motion Chart using World Bank's World Development Index. |access-date=2 October 2011 |archive-url=https://web.archive.org/web/20110827110525/http://homepage3.nifty.com/sociology/motion.html |archive-date=27 August 2011 |url-status=dead }}</ref>{{elucidate|date=November 2012}}
In [[undeveloped countries]] on the other hand, families desire children for their labour and as caregivers for their parents in old age. Fertility rates are also higher due to the lack of access to [[contraceptives]], generally lower levels of [[female education]], patriarchal culture and lower rates of female employment in industry.

For the group aged below 15, [[Sierra Leone]] has the highest female ratio with 0.96 males/female, and [[Georgia (country)|Georgia]] and China are tied for the highest male ratio with 1.13 males/female (according to the 2006 [[The World Factbook|CIA World Factbook]]).
The "[[First World]]" [[G7]] members all have a gender ratio in the range of 0.95–0.98 for the total population, of 1.05–1.07 at birth, of 1.05–1.06 for the group below 15, of 1.00–1.04 for the group aged 15–64, and of 0.70–0.75 for those over 65.
Countries on the [[Arabian Peninsula]] tend to have a "natural" ratio of about 1.05 at birth but a very high ratio of males for those over 65 ([[Saudi Arabia]] 1.13, [[United Arab Emirates]] 2.73, [[Qatar]] 2.84), indicating either an above-average mortality rate for females or a below-average mortality for males, or, more likely in this case, a large population of aging male [[foreign worker|guest workers]]. Conversely, countries of [[Eastern Europe]] (the [[Baltic states]], [[Belarus]], [[Ukraine]], [[Russia]]) tend to have a "normal" ratio at birth but a very low ratio of males among those over 65 (Russia 0.46, Latvia 0.48, Ukraine 0.52); similarly, [[Armenia]] has a far above average male ratio at birth (1.17), and a below-average male ratio above 65 (0.67). This effect may be caused by [[human migration|emigration]] and higher male mortality as result of higher post-Soviet era deaths; it may also be related to the enormous (by western standards) rate of alcoholism in the former Soviet states. Another possible contributory factor is an aging population, with a higher than normal proportion of relatively elderly people: we recall that due to higher differential mortality rates the ratio of males to females reduces for each year of age.
==Unemployment rate==
8.7% (2010 est.)
8.2% (2009 est.)
note: 30% combined unemployment and underemployment in many non-industrialized countries; developed countries typically 4%–12% unemployment (2007 est.)

{{Main|Language family}}
Worldwide, [[English language|English]] is used widely as a [[lingua franca]] and can be seen to be the dominant language at this time. The world's largest language by native speakers is [[Mandarin Chinese]] which is a [[first language]] of around 960 million people, or 12.44% of the population, predominantly in [[Greater China]]. [[Spanish language|Spanish]] is spoken by around 330 to 400 million people, predominantly in the [[Americas]] and [[Spain]]. [[Hindi]] is spoken by about 370 to 420 million speakers, mostly in [[India]] and [[Pakistan]].
[[Arabic language|Arabic]] is spoken by around 350 million people predomimantly in [[Arab world]]. [[Bengali language|Bengali]] is spoken by around 250 million people worldwide, predominantly in [[Bangladesh]] and India. [[Portuguese language|Portuguese]] is spoken by about 230 million speakers in [[Portugal]], [[Brazil]], [[East Timor]], and [[Southern Africa]].
There are numerous other languages, grouped into nine major families:
# [[Indo-European languages]] 46% ([[Europe]], [[Western Asia]], [[South Asia]], [[North Asia]], [[North America]], [[South America]], and [[Oceania]])
# [[Sino-Tibetan languages]] 21% ([[East Asia]], [[Mainland Southeast Asia]], and [[South Asia]])
# [[Niger–Congo languages]] 6.4% ([[Sub-Saharan Africa]])

# [[Austronesian languages]] 5.9% ([[Oceania]], [[Madagascar]], and [[Maritime Southeast Asia]])
# [[Dravidian languages]] 3.7% ([[South Asia]])
# [[Altaic languages]] (controversial combination of Turkic, Mongolic, and Tungusic families) 2.3% ([[Central Asia]], [[North Asia]] ([[Siberia]]), and [[Anatolia]]){{efn|1=Since the Mongolic and Tungusic language families have only a relatively small number of speakers, the majority of the Altaic percentage represents speakers of Turkic languages.}}

== History ==
[[File:Illustration of contemporary and past human populations Our World in Data.png|thumb|Comparison of humans living today with all previous generations]]
Historical migration of human populations begins with the movement of ''[[Homo erectus]]'' out of Africa across [[Eurasia]] about a million years ago. ''[[Human|Homo sapiens]]'' appear to have occupied all of Africa about 300,000 years ago, moved out of Africa 50,000 – 60,000 years ago, and had spread across [[Prehistory of Australia|Australia]], [[History of Asia|Asia]] and [[Paleolithic Europe|Europe]] by 30,000 years BC. [[Models of migration to the New World|Migration to the Americas]] took place 20,000 to 15,000 years ago, and by 2,000 years ago, most of the [[Pacific Islands]] were colonized.
Until c. 10,000 years ago, humans lived as [[hunter-gatherer]]s. They generally lived in small nomadic groups known as [[band societies]]. The advent of agriculture prompted the [[Neolithic Revolution]], when access to food surplus led to the formation of permanent [[human settlement]]s. About 6,000 years ago, the first proto-states developed in [[Mesopotamia]], [[Egypt]]'s [[Nile Valley]] and the [[Indus Valley civilisation|Indus Valley]]. Early human settlements were dependent on proximity to [[water resources|water]] and, depending on the [[lifestyle (sociology)|lifestyle]], other [[natural resources]] used for [[subsistence economy|subsistence]]. But humans have a great capacity for altering their [[habitat (ecology)|habitats]] by means of technology.
Since 1800, the [[human population]] has increased from one billion<ref>{{cite news | url = http://news.bbc.co.uk/1/hi/sci/tech/411162.stm | access-date = 5 February 2008 | work=BBC News | title=World's population reaches six billion | date=5 August 1999}}</ref> to nearly eight billion,<ref name=7billpop>{{cite web|title=UN population estimates.|url=http://esa.un.org/unpd/wpp/unpp/p2k0data.asp|work=Population Division, United Nations|access-date=4 July 2013}}</ref> In 2004, some 2.5 billion out of 6.3 billion people (39.7%) lived in [[urban area]]s.

{{Further|List of religious populations}}
[[File:Prevailing world religions map.png|thumb|upright=1.25|Major denominations and religions of the world]]
The table below lists religions classified by philosophy; however, religious philosophy is not always the determining factor in local practice. Please note that this table includes heterodox movements as adherents to their larger philosophical category, although this may be disputed by others within that category. For example, [[Caodaism|Cao Đài]] is listed because it claims to be a separate category from Buddhism, while [[Hòa Hảo]] is not, even though they are similar [[new religious movement]]s.
The population numbers below are computed by a combination of census reports, random surveys (in countries where religion data is not collected in census, for example United States or France), and self-reported attendance numbers, but results can vary widely depending on the way questions are phrased, the definitions of religion used and the bias of the agencies or organizations conducting the survey. Informal or unorganized religions are especially difficult to count. Some organizations may wildly inflate their numbers.

Since the late 19th century, the demographics of religion have changed a great deal. Some [[Western culture|countries with a historically large Christian population]] have experienced a significant decline in the numbers of professed active Christians: see [[demographics of atheism]]. Symptoms of the decline in active participation in Christian religious life include declining recruitment for the [[priest]]hood and [[monastery|monastic life]], as well as diminishing [[Church attendance|attendance at church]]. On the other hand, since the 19th century, large areas of [[sub-Saharan Africa]] have been converted to Christianity, and this area of the world has the highest population growth rate. In the realm of [[Western culture|Western civilization]], there has been an increase in the number of people who identify themselves as [[secular humanism|secular humanists]]. Despite the decline, [[Christianity]] remains the dominant religion in the [[Western world]], where 70% of the population is Christian.<ref name="Global Christianity">{{cite web|author=Analysis |url=http://www.pewforum.org/Christian/Global-Christianity-exec.aspx |title=Global Christianity |publisher=Pew Research Center |date=19 December 2011 |access-date=17 August 2012}}</ref> In many countries, such as the People's Republic of China, communist governments have discouraged religion, making it difficult to count the actual number of believers. However, after the collapse of communism in numerous countries of Eastern Europe and the former [[Soviet Union]], religious life has been experiencing resurgence there, in the form of traditional [[Eastern Christianity]].<ref name="Pew Research Center1">{{Cite web|url=https://www.pewforum.org/2018/10/29/eastern-and-western-europeans-differ-on-importance-of-religion-views-of-minorities-and-key-social-issues/|title=Eastern and Western Europeans Differ on Importance of Religion, Views of Minorities, and Key Social Issues|work=Pew Research Center|date=October 29, 2018}}</ref> While, Islam however has gained considerably in the Soviet Unions former republics in [[Central Asia]].

Some [[Western Europe]] countries might also encounter negative population growth.<ref>[http://esa.un.org/unpp/index.asp?panel=2 UN population projections] {{webarchive|url=https://web.archive.org/web/20100914023416/http://esa.un.org/UNPP/index.asp?panel=2 |date=14 September 2010 }}</ref> [[Japan]]'s population began decreasing in 2005.<ref>{{cite news |url=https://www.theguardian.com/world/2009/jan/02/japan-population |title=Japan sees biggest population fall |work=The Guardian |access-date=6 September 2018}}</ref>
Population in the world increased from 1990 to 2008 with 1,423 billion and 27% growth. Measured by persons, the increase was highest in [[India]] (290 million) and China (192 million). Population growth was highest in [[Qatar]] (174%) and [[United Arab Emirates]] (140%).<ref name=IEApop2011>[http://www.iea.org/co2highlights/co2Highlights.XLS CO2 Emissions from Fuel Combustion] {{Webarchive|url=https://web.archive.org/web/20091012151137/http://www.iea.org/co2highlights/co2Highlights.XLS |date=12 October 2009 }} Population 1971–2008 IEA ([http://iea.org/co2highlights/co2highlights.pdf pdf] {{Webarchive|url=https://web.archive.org/web/20120106205757/http://iea.org/co2highlights/co2highlights.pdf |date=6 January 2012 }} pages 83–85)</ref>
In 2022 the world population reached the 8 billion.

According to the [[The World Factbook|CIA – The World Factbook]], the country with the highest birth rate currently is Niger at 51.26 births per 1000 people. The country with the lowest birth rate is Japan at 7.64 births per 1000 people. Hong Kong, a Special Administrative Region of China, is at 7.42 births per 1000 people.

Birth rates vary even within the same geographic areas. In Europe, as of July 2011, Ireland's birth rate is 16.5 percent, which is 3.5 percent higher than the next-ranked country, the UK. France has a birth rate of 12.8 per cent while Sweden is at 12.3 percent.<ref>{{cite web|url=http://www.thejournal.ie/ireland-has-one-of-highest-birth-and-lowest-death-rates-in-eu-189080-Jul2011/ |title=Ireland has one of highest birth and lowest death rates in EU |work=Thejournal.ie |date=29 July 2011 |access-date=6 September 2018}}</ref> In July 2011, the UK's Office for National Statistics (ONS) announced a 2.4% increase in live births in the UK in 2010 alone.<ref name="guardian1">{{cite news |url=https://www.theguardian.com/society/2011/jul/13/more-midwives-birth-rate-40-year-high |title=Call for more midwives as birth rate reaches 40-year high |work=The Guardian |date=13 July 2011 |access-date=6 September 2018}}</ref> This is the highest birth rate in the UK in 40 years.<ref name="guardian1"/> By contrast, the birth rate in Germany is only 8.3 per 1,000, which is so low that both the UK and France, which have significantly smaller populations, produced more births in 2010.<ref>{{cite news |url=http://www.irishtimes.com/newspaper/health/2011/0809/1224302081071.html |title=Germany faces up to its kinder surprise |newspaper=The Irish Times |date=9 June 2018 |access-date=6 September 2018}}</ref> Birth rates also vary within the same geographic area, based on different demographic groups. For example, in April 2011, the U.S. CDC announced that the birth rate for women over the age of 40 in the U.S. rose between 2007 and 2009, while it fell among every other age group during the same time span.<ref>{{cite news |url=http://www.cnn.com/2011/HEALTH/04/01/cdc.births.decline/index.html |title=CDC records rise in birth rate for women over 40 |work=CNN.com |access-date=6 September 2018}}</ref> In August 2011, Taiwan's government announced that its birth rate declined in the previous year, despite the fact that it implemented a host of approaches to encourage its citizens to have babies.<ref>{{cite news |url=https://www.bbc.co.uk/news/world-asia-pacific-14525525 |title=Taiwanese birth rate plummets despite measures |work=BBC News |access-date=6 September 2018}}</ref>
Birth rates ranging from 10 to 20 births per 1000 are considered low, while rates from 40 to 50 births per 1000 are considered high. There are problems associated with both an extremely high birth rate and an extremely low birth rate. High birth rates can cause stress on the government welfare and family programs to support a youthful population. Additional problems faced by a country with a high birth rate include educating a growing number of children, creating jobs for these children when they enter the workforce, and dealing with the environmental effects that a large population can produce. Low birth rates can put stress on the government to provide adequate senior welfare systems and also the stress on families to support the elders themselves. There will be less children or working age population to support the constantly growing aging population.
The ten countries with the highest and lowest crude birth rate, according to the 2018 and 2022 [[The World Factbook|CIA World Factbook]] estimates, are:<ref>{{cite web |title=Birth rate - The World Factbook |url=https://www.cia.gov/the-world-factbook/field/birth-rate/ |website=www.cia.gov |access-date=25 July 2022}}</ref>

See [[list of countries by mortality rate]] for worldwide statistics.
According to the [[World Health Organization]], the 10 leading [[causes of death]] in 2002 were:
<!-- ref: http://www.who.int/entity/whr/2004/annex/topic/en/annex_2_en.pdf -->
# 12.6% [[Ischemic heart disease]]
# 9.7% [[Cerebrovascular disease]]
# 6.8% [[Lower respiratory infection]]s
# 4.9% [[HIV/AIDS]]
# 4.8% [[Chronic obstructive pulmonary disease]]
# 3.2% [[Diarrhoeal disease]]s
# 2.7% [[Tuberculosis]]
# 2.2% [[Trachea/bronchus/lung cancers]]
# 2.2% [[Malaria]]
# 2.1% [[Road traffic accidents]]
Causes of death vary greatly between first and third world countries.
According to [[Jean Ziegler]] (the [[United Nations]] Special Rapporteur on the Right to Food for 2000 to March 2008), mortality due to [[malnutrition]] accounted for 58% of the total mortality in 2006: "In the world, approximately 62 millions people, all causes of death combined, die each year. In 2006, more than 36 millions died of hunger or diseases due to deficiencies in [[micronutrients]]".<ref name=Ziegler>[[Jean Ziegler]], ''[[L'Empire de la honte]]'', Fayard, 2007 {{ISBN|978-2-253-12115-2}}, p.130.</ref>
Of the roughly 150,000 people who died each day across the globe, about two-thirds—100,000 per day—died of age-related causes in 2001, according to an article which counts all deaths "due to causes that kill hardly anyone under the age of 40" as age-related.<ref name="doi10.2202/1941-6008.1011">{{cite journal | last = Aubrey D.N.J | first = de Grey | author-link = Aubrey de Grey | title = Life Span Extension Research and Public Debate: Societal Considerations | journal = Studies in Ethics, Law, and Technology | volume = 1 | issue = 1, Article 5 | year = 2007 | url = http://www.sens.org/files/pdf/ENHANCE-PP.pdf | doi = 10.2202/1941-6008.1011 | access-date = 7 August 2011 | citeseerx = 10.1.1.395.745 | s2cid = 201101995 | archive-url = https://web.archive.org/web/20161013163622/http://www.sens.org/files/pdf/ENHANCE-PP.pdf | archive-date = 13 October 2016 | url-status = dead }}</ref>{{better source needed|| reference uses an extremely broad definition of "age-related" deaths, including even traffic accidents due to poor eyesight|date=June 2018}} In industrialized nations, the proportion was even higher according to that article, reaching 90%.<ref name="doi10.2202/1941-6008.1011"/>
== Total fertility rate ==
{{See also|List of sovereign states and dependencies by total fertility rate}}
The [[Total fertility rate]] is the average number of children born per mother. In 2021, fertility levels high were found in sub-Saharan Africa (4.6 births per woman), Oceania excluding Australia and New Zealand (3.1), Northern Africa and Western Asia
(2.8), and Central and Southern Asia (2.3).<ref name="unorgde"/>
There is an inverse correlation between [[income and fertility]], wherein [[Developed country|developed countries]] usually have a much lower [[fertility rate]]. Various [[fertility factor (demography)|fertility factors]] may be involved, such as education and urbanization. [[Mortality rate]]s are low, [[birth control]] is understood and easily accessible, and costs are often deemed very high because of education, clothing, feeding, and social amenities. With wealth, contraception becomes affordable. However, in countries like Iran where contraception was made artificially affordable before the economy accelerated, birth rate also rapidly declined. Further, longer periods of time spent getting higher education often mean women have children later in life.<ref>{{Cite news|last=Gallagher|first=James|date=15 July 2020|title='Jaw-dropping' world fertility rate crash expected|language=en-GB|work=BBC News|url=https://www.bbc.com/news/health-53409521|access-date=18 July 2020}}</ref> Female labor participation rate also has substantial negative impact on fertility. However, this effect is neutralized among Nordic or liberalist countries.<ref>{{Cite web |url=http://homepage3.nifty.com/sociology/motion.html |title=Graph Charts of TFR and FLR using Google Motion Chart using World Bank's World Development Index. |access-date=2 October 2011 |archive-url=https://web.archive.org/web/20110827110525/http://homepage3.nifty.com/sociology/motion.html |archive-date=27 August 2011 |url-status=dead }}</ref>{{elucidate|date=November 2012}}
In [[undeveloped countries]] on the other hand, families desire children for their labour and as caregivers for their parents in old age. Fertility rates are also higher due to the lack of access to [[contraceptives]], generally lower levels of [[female education]], patriarchal culture and lower rates of female employment in industry.

The value for the entire [[world population]] is 1.02 males/female,<ref name="CIA Fact Book">{{cite web|title=CIA Fact Book |date=15 November 2021 |url=https://www.cia.gov/the-world-factbook/countries/world/ |publisher=The Central Intelligence Agency of the United States }}</ref> with 1.07 at birth, 1.06 for those under 15, 1.02 for those between 15 and 64, and 0.78 for those over 65.
The [[Northern Mariana Islands]] have the highest female ratio with 0.77 males per female. [[Qatar]] has the highest male ratio, with 2.87 males/female. For the group aged below 15, [[Sierra Leone]] has the highest female ratio with 0.96 males/female, and [[Georgia (country)|Georgia]] and China are tied for the highest male ratio with 1.13 males/female (according to the 2006 [[The World Factbook|CIA World Factbook]]).
The "[[First World]]" [[G7]] members all have a gender ratio in the range of 0.95–0.98 for the total population, of 1.05–1.07 at birth, of 1.05–1.06 for the group below 15, of 1.00–1.04 for the group aged 15–64, and of 0.70–0.75 for those over 65.
Countries on the [[Arabian Peninsula]] tend to have a "natural" ratio of about 1.05 at birth but a very high ratio of males for those over 65 ([[Saudi Arabia]] 1.13, [[United Arab Emirates]] 2.73, [[Qatar]] 2.84), indicating either an above-average mortality rate for females or a below-average mortality for males, or, more likely in this case, a large population of aging male [[foreign worker|guest workers]]. Conversely, countries of [[Eastern Europe]] (the [[Baltic states]], [[Belarus]], [[Ukraine]], [[Russia]]) tend to have a "normal" ratio at birth but a very low ratio of males among those over 65 (Russia 0.46, Latvia 0.48, Ukraine 0.52); similarly, [[Armenia]] has a far above average male ratio at birth (1.17), and a below-average male ratio above 65 (0.67). This effect may be caused by [[human migration|emigration]] and higher male mortality as result of higher post-Soviet era deaths; it may also be related to the enormous (by western standards) rate of alcoholism in the former Soviet states. Another possible contributory factor is an aging population, with a higher than normal proportion of relatively elderly people: we recall that due to higher differential mortality rates the ratio of males to females reduces for each year of age.
==Unemployment rate==
8.7% (2010 est.)
8.2% (2009 est.)
note: 30% combined unemployment and underemployment in many non-industrialized countries; developed countries typically 4%–12% unemployment (2007 est.)
== Languages ==
[[File:Primary Human Languages Improved Version.png|thumb|right|upright=1.25|Primary language families of the world (and in some cases geographic groups of families). For greater detail, see ''[[:Distribution of languages in the world|Distribution of languages in the world]]''.]]
{{Main|Language family}}
Worldwide, [[English language|English]] is used widely as a [[lingua franca]] and can be seen to be the dominant language at this time. The world's largest language by native speakers is [[Mandarin Chinese]] which is a [[first language]] of around 960 million people, or 12.44% of the population, predominantly in [[Greater China]]. [[Spanish language|Spanish]] is spoken by around 330 to 400 million people, predominantly in the [[Americas]] and [[Spain]]. [[Hindi]] is spoken by about 370 to 420 million speakers, mostly in [[India]] and [[Pakistan]].
[[Arabic language|Arabic]] is spoken by around 350 million people predomimantly in [[Arab world]]. [[Bengali language|Bengali]] is spoken by around 250 million people worldwide, predominantly in [[Bangladesh]] and India. [[Portuguese language|Portuguese]] is spoken by about 230 million speakers in [[Portugal]], [[Brazil]], [[East Timor]], and [[Southern Africa]].
There are numerous other languages, grouped into nine major families:
# [[Indo-European languages]] 46% ([[Europe]], [[Western Asia]], [[South Asia]], [[North Asia]], [[North America]], [[South America]], and [[Oceania]])
# [[Sino-Tibetan languages]] 21% ([[East Asia]], [[Mainland Southeast Asia]], and [[South Asia]])
# [[Niger–Congo languages]] 6.4% ([[Sub-Saharan Africa]])
# [[Afroasiatic languages]] 6.0% ([[North Africa]] to [[Horn of Africa]], and [[Western Asia]])
# [[Austronesian languages]] 5.9% ([[Oceania]], [[Madagascar]], and [[Maritime Southeast Asia]])
# [[Dravidian languages]] 3.7% ([[South Asia]])
# [[Altaic languages]] (controversial combination of Turkic, Mongolic, and Tungusic families) 2.3% ([[Central Asia]], [[North Asia]] ([[Siberia]]), and [[Anatolia]]){{efn|1=Since the Mongolic and Tungusic language families have only a relatively small number of speakers, the majority of the Altaic percentage represents speakers of Turkic languages.}}
# [[Austroasiatic languages]] 1.7% ([[Mainland Southeast Asia]])
# [[Kra–Dai languages]] 1.3% ([[Southeast Asia]])
There are also hundreds of [[List of sign languages|non-verbal sign languages]].
