Houston 311 Data Explorer
Every time a Houstonian reports a pothole, a missed trash pickup, or a water leak, it becomes a 311 service request. We map and chart that data so you can see how responsive the city is in your neighborhood.

“I'm the Data Detective. I follow the clues in Houston's data to find numbers that don't add up — missing values, duplicates, and impossible dates. Want to crack your first case?”
Data Detective: Across 900 service requests, 101 neighborhoods are represented. I flagged 36 records worth a second look — they're marked red on the map.
