ACS – Answering my own question

(hat tip to Dr. Gridlock)

In earlier posts, I wondered what DC’s regional transit data looks like – and with the release of the 2006-2008 three-year estimates from the American Community Survey, we have some answers.

Data is available for the Washington, DC urbanized area.  That area looks like this:

So, that includes a lot of stuff, and a whole lot of suburbia.

The transportation data is as follows:

COMMUTING TO WORK
Workers 16 years and over 2,221,629 +/-8,331 2,221,629 (X)
Car, truck, or van — drove alone 1,415,834 +/-9,036 63.7% +/-0.3
Car, truck, or van — carpooled 237,724 +/-5,008 10.7% +/-0.2
Public transportation (excluding taxicab) 363,334 +/-5,319 16.4% +/-0.2
Walked 77,067 +/-2,795 3.5% +/-0.1
Other means 33,023 +/-1,979 1.5% +/-0.1
Worked at home 94,647 +/-3,018 4.3% +/-0.1

So, 63.7% of the region’s workers commute in a single-occupant vehicle, with 16.4% using transit.  For the same three year window (2006-2008), DC’s stats look like this:

COMMUTING TO WORK
Workers 16 years and over 293,532 +/-3,568 293,532 (X)
Car, truck, or van — drove alone 108,373 +/-3,363 36.9% +/-1.0
Car, truck, or van — carpooled 19,121 +/-1,591 6.5% +/-0.5
Public transportation (excluding taxicab) 108,687 +/-2,469 37.0% +/-0.8
Walked 34,455 +/-2,033 11.7% +/-0.7
Other means 9,421 +/-1,023 3.2% +/-0.3
Worked at home 13,475 +/-1,451 4.6% +/-0.5

36.9% drove alone, while 37.0% used transit.

Note that this is the rolling three-year sample, so the data is slightly different from the 2008 ACS data released earlier.
