This document summarizes check-in data from Foursquare over a one week period in September 2012. It finds that there were over 22 million total check-ins during the week, with about 2.7 million per day. 56% of check-ins were by males. An analysis of check-in locations in New York and California shows that health conscious individuals checked in more frequently in New York per capita. An examination of check-in data from a football game reveals an unusually high number of check-ins that was ultimately explained by a new Foursquare badge promotion for the team.
