The Consumer Financial Protection Bureau (CFPB) has been collecting consumer complaints for 3 years, and has apparently been collecting them into one of the most usable government databases I've ever seen. This is particularly neat given the qualitative nature of many of these complaints. The CFPB was only created in 2011 after the 2010 passage of the Dodd–Frank Wall Street Reform and Consumer Protection Act, which might explain why its website appears far more modern than most federal endeavors. The data has a lot of potential, but here are a few tidbits I grabbed right away.
First, I noticed that each complaint was entered with a zipcode, and I wondered which had seen the most complaints. Here's the top ten, along with their actual location (first town name result based on a quick google search).
Florida and California are both well-represented, although I was surprised to see a Michigan zip code take the top spot. Perhaps these are areas with high concentrations of retired individuals?
In a similar vein, here are the top ten "Issues" reported in the database.
