TNC Trip Characteristics
The density cut-off used here is consistent with research showing that people living in neighborhoods with more than 4,000 persons per square mile tend to see themselves as living in urban neighborhoods; conversely, those living in areas with fewer than 4,000 persons per square mile tend to see their neighborhoods as suburban or rural.
- "Urban - 9 metros" is for metro areas with the largest concentration of ride-hail usage (Boston, Chicago, Los Angeles, Miami, New York, Philadelphia, San Francisco, Seattle and Washington DC). Includes the portions of these metros with 4,000 or more persons per square mile.
- "Other urban" covers all other census tracts in the U.S. with 4,000 or more persons per square mile.
- "Suburban/rurual" covers census tracts with fewer than 4,000 persons per square mile.
The urban category includes virtually the entire populations of large, dense cities such as New York, Chicago and Philadelphia, as well as the relatively dense portions of their suburbs. “Urban” census tracts also cover most of the population of large but less dense cities such as Baltimore, Detroit, Minneapolis and Milwaukee. In addition, there are numerous urban-density census tracts in smaller cities and towns, primarily in older, walkable residential neighborhoods.
Maps of selected metro areas showing census tracts classified as urban is available here.
