Smaller lots and the mixing of compatible uses within and around town centres and near public transport creates the higher densities needed to support destinations and services that residents can easily reach by walking or cycling.
Residential density, at its simplest, is a measure of the number of residents or dwellings in a given area. But there is no universally agreed definition of residential density, and different professions have applied and defined the concept in various ways.

In the literature on physical activity, residential density has typically been defined as the number of people living in a given area (population per hectare) or the number of housing units in an area (residences per hectare).
