In this installment of my “By the Numbers” feature, I am looking at the location-based social network foursquare.

foursquare began as a gamified check-in app and has evolved into a discovery engine of sorts mixing in a social aspect to local search.

foursquare was the darling of SXSW shortly after it launched in 2009 and they enjoyed rapid expansion during their first year or so of existence. Since then, the momentum has slowed somewhat, but foursquare has a very loyal user base and businesses of all sizes have embraced the platform’s very useful marketing features.

So how many people and businesses are using foursquare these days? Here are those foursquare stats and a bunch more:

Please note that some of these numbers are easier to find than others. A few of these stats come from foursquare’s own reports, but some are based on news reports and not official company tallies. Basically, this is the best I can find and I don’t guarantee anything to be 100% accurate.
