Marchetti posits that although forms of urban planning and transport may change, and although some live in villages and others in cities, people gradually adjust their lives to their conditions (including location of their homes relative to their workplace) such that the average travel time stays approximately constant.
Yeah, that's a strange conclusion.
887 thousands.
So, less than the Bronx (1.4M), but more than Staten Island (450k).
About the same as Indianapolis, IN, USA or Donetsk, Ukraine.
So, 1 medium city's worth.
