Urban density is a term used in urban planning and urban design to refer to the number of people inhabiting a given urbanized area. As such it is to be distinguished from other measures of population density. Urban density is considered an important factor in understanding how cities function. Research related to urban density occurs across diverse areas, including economics, health, innovation, psychology and geography as well as sustainability.
Urban density and sustainability
It is commonly asserted that higher density cities are more sustainable than low density cities. Much planning theory has been developed premised on raising urban densities, such as New Urbanism, Transit-oriented development, and Smart growth.
However, the link between urban density and aspects of sustainability remains a contested area of planning theory. Many experts on sustainable urbanism argue that low-density, dispersed cities are unsustainable as they are automobile dependent. Others counter that raising densities results in more expensive real estate, greater road congestion and more air pollution. At a broader level though, there is evidence to indicate a strong correlation between the total energy consumption of a city and its overall urban density, i.e. the lower the density, the more energy consumed.
