Thanks so much for posting this! I look forward to your more detailed breakdowns. Exciting news, reinforces what many of us are experiencing anecdotally.

JR,

Thank you for your comment. What you point out is especially important for smaller communities which sometimes have very small sample sizes leading to much larger margins of errors.We will highlight this and other issues with the ACS when we provide the more detailed breakdowns.

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 you cite estimated data (e.g. ACS) it is useful to remind folks that there is a range of values to consider. In some cases the range can be quite large and may affect your analysis.
