Re: Driven By Customer 'Service' Parte Dos
Those car numbers are still so high! I wonder what the data would show for something smaller than MSA, like city proper or contiguous urban area.
Here's your answer for
Boston, Cambridge, Newton, and "Framingham" (Framingham, as a CDP* may span several juridical towns and be the Census' way of saying "outer suburbs")
Locat'n: SOV ___ Transit ___ Walk ___ Bike
Boston: 40.6% ___33.0% ___14.5% ___ 1.9%
Cambr: 30.9% ___ 27.7% ___ 25.1% ___ 6.5% (note Harvard/MIT "walk" influence)
Newton: 67.2% ___ 11.0% ___ 4.7% ___ 1.4% (proxy for "inner" burbs?)
Frmhm: 73.4% ___ 5.2% ___ 5.2% ___ 0.6% (proxy for "far 'burbs")
This comes from the American Community Survey table S0801, "
Commuting Characteristics by Sex" **
These numbers have fairly substantial margins of error, so scrolling to multiple-year sources lowers the margins but makes trend-spotting less fun/valid.
=============== Census Data Tips =================
*Census-Designated Place (kind of like saying "Route 128" or "North Shore" it can have different boundaries for the Census Bureau than "real life" or legally or what you'd think)
** 'by sex' is their way of saying "for everybody": it gives the biggest aggregation of responses and the lowest margin of error, and sometimes (as with biking) is the only way to get at very rare trends. If you cut it any finer, like by education, race, or income, the number of responses in each bucket gets too small and the margin of error gets nearly as big as thing you're trying to measure
