"Commuter-adjusted populations tell us a lot about where the jobs are and which communities do little more than give people a place to sleep. Count people where they work, and not where they live, and the resulting picture also further blurs the divide between cities and suburbs (and how we think about who is invested in which places)."

See the recent article on The Atlantic Cities on "The Most Important Population Statistic That Hardly Ever Gets Talked About". The article discusses about the underscored importance of the "commuter-adjusted population" metric which can be obtained from the American Community Survey Data.
Some insightful statistics:
- Total number of trips in the 1st quarter 2013 was 46,598 while the total number of trips in the 2nd quarter 2012 was 572,919. More than 12 times larger. Showing the seasonal effect of bike-sharing demand.
- Most of the trips were between 10 to 20 minutes. Trip duration could be a function of the pricing policy and the actual length of a trip.
- In the 1st quarter 2013, average trip duration was 14 minutes while in the 2nd quarter 2012, the average trip duration was 19 minutes.
- In the 1st quarter 2013, only about 1% of the trips started and ended at the same station, while in the 2nd quarter 2012, 5% of the trips started and ended at the same station. Starting and ending a trip at the same location could be an indication of a leisure trip.
- In the 1st quarter 2013, about 6% of the trips were longer than 30 minutes but smaller than 60 minutes while in the 2nd quarter 2012, about 10% of the trips violated the 30 minute limit of the free ride policy.

A recent article on the Atlantic Cities on "Bike-Share May Not Take Many Cars Off the Road, But That's OK" suggests that bike-share programs can actually work as an extension to public transit and make less accessible by transit places, more accessible by transit-and-bike. Putting bike-share stations at transit stations sounds like a good idea.
