    Density Population & employment by geographic unit (e.g., per square mile, per developed acre).
    Diversity Mix of land uses, typically residential and commercial development, and the degree to which they are balanced in an area (e.g., jobs–housing balance).
    Design Neighborhood layout and street characteristics, particularly connectivity, presence of sidewalks, and other design features (e.g., shade, scenery, presence of attractive homes and stores) that enhance the pedestrian- and bicycle-friendliness of an area.
    Destination accessibility
    Ease or convenience of trip destinations from point of origin, often measured at the zonal level in terms of distance from the central business district or other major centers.
    Distance to transit
    Ease of access to transit from home/work (e.g., bus/rail stop within ¼ to ½ mile).
