The Wall Street Journal has published a fascinating, in-depth analysis of user data from location sharing app Foursquare for San Francisco and New York. The idea: to look at differences between behaviour patterns in the two cities.
A weeks worth of user data from January 2011 is visualized on an animated series of heat maps highlighting where the most check-ins occurred. Further charts and maps break down details into most popular venues and categories, also comparing the two sexes.
When it comes to the biggest differences between cities:
New Yorkers go for bars, train stations and corporate offices, while Bay Area residents prefer coffee shops, grocery stores, gas stations and light rail.
