Mobile, AL, settled by French colonists in the early 18th century, Tulsa, OK, a 19th century farming town, and Anchorage, AK, a 20th century frontier town, all share the same 300′ x 300′ internal block (street widths vary a little). I assumed the more western and newer cities would have larger grids than the more eastern and older cities, but no obvious pattern is discernible to me.

Tags: bus, Data Visualization, france, metro, processing, public transportation, transportation All queries are sent from Nantes through the SNCF website March 1 2010. The connection from Nantes to other cities of France: width of lines shows frequency of travels transparency shows the proportion of such connection in all transportations carried by that city. We can see different dependency on public transportation in each region.

The same thing was happening even back in 1790: New York was the biggest single city, but Philadelphia plus its suburbs of Northern Liberties and Southwark made it the biggest metro area. For example, in 2000 San Antonio was the 10th largest city in the U.S., larger than Boston or San Francisco, but its Metro Area was only ranked about 30th. Metropolitan area population is much more useful than city population as an indicator of the size and importance of a city, since the official boundaries of a city are usually arbitrary and often do not include vast suburban areas. The statistic used here is the population of the metropolitan area (contiguous urbanized area surrounding a central city), not the population of an individual city. The graph and tables on this page attempt to show how the urban hierarchy of the United States has developed over time.
