Does the city collect bike-use data? I've known of cities that conduct more extensive bike and pedestrian surveys at the same time as the Census ACS, so that the data can be compared on fairly equal terms.

Bikies,

Actually, IS there a source for all-the-numbers for the U.S. on total bicycle fleet size, bikes per capita, total bike commuters, percentage of commuters by mode, more....? I´d like to see that ["official" numbers] to try to figure out if I can find numbers to compare them to here in Brazil where they say the total bike fleet is 65 million and growing rapidly.

Blog post by somebody called JR:
http://www.bikeleague.org/blog/2009/09/43-increase-in-bicycle-commuting-since-2000/
"The number of bike commuters was estimated to be 786,098 +/- 16,011. If you also consider that the total number of commuters (the denominator) has a spread of +/- 139,905 the percentages could range from 0.534% in the worst case and 0.558% in the best case. So, even in the worst case scenario it seems that there has been a significant growth in bicycle commuting (hooray!)."

When I dig through the Census ACS data (http://www.census.gov/acs) I find tables that include the following examples but nothing specifically about bicycles - perhaps only by getting at the live data:
Means of Transportation to Work
-Car, truck, or van - drove alone:
-Car, truck, or van - carpooled
-Public transportation (excluding taxicab)
-Taxicab, motorcycle, bicycle, walked, or other means
-Worked at home

If there is a bike-centric collection of data from the US Census online I´d appreciate any pointers to that.

Thx

And apparently this is up 43% from 2000.
