Interesting little table that she’s put together over at the Planning Livable Communities website/blog.
It uses data from the US Census to chart what happens each day – how do cities and towns shrink or grow as workers flow in and out.
Boston, for example, had 589,141 residents, in 2000. During the day, an additional 242,000 people commuted into the city to work. Meanwhile, of the 589,141 residents, 66% both lived and worked in the city.
There is data for other cities and towns of size, as well.
