Colors are relative to what’s currently on screen, so they adjust as you switch time ranges.

Zoomed into a neighborhood or zip? Same colors group nearby reports, and a bright dot means that exact spot’s been reported more than once.

Why Chicago keeps score on its rats

Chicago has topped national rankings of the rattiest U.S. cities for over a decade running — a reputation the city itself takes seriously enough to run one of the country’s most active 311 rodent-complaint programs. Every baiting request, burrow report, and complaint filed with the city becomes a public record. RatCity turns that record, plus reports from people who live here, into a map you can actually use: is this block bad? Is it getting worse? Which neighborhood is winning (or losing) the fight this month?

What’s actually on the map

Most of the data is Chicago’s own — every “Rodent Baiting/Rat Complaint” filed through 311, pulled in automatically once a day so the map never goes stale. Layered on top are sightings reported directly by visitors, matched to the same neighborhood and zip-code boundaries the city uses, so a resident’s report and an official 311 complaint carry equal weight on the map.

Reading the map

Circles are sized and colored by how many reports a neighborhood has racked up — blue is quiet, red means trouble. The Day / Week / 30 Days / Year toggle up top changes the window, so you can see whether a neighborhood’s rat problem is a one-week blip or a year-long trend. Whoever’s in the lead gets crowned the neighborhood Rat King in the sidebar, a title that changes hands as new reports come in.

Noticed a rat that isn’t on the map yet? Use “Report a sighting” above — it takes under a minute and goes live as soon as it’s reviewed. Curious about where the data actually comes from or how reports are moderated? See the About page for the full breakdown.
