How these measures work
Resolved in 7 days is the default because it can’t be gamed by a backlog: it counts every request old enough to have had a week, and a request still open past that deadline counts as a miss. A closed-cases-only average makes backlogged areas look fast, because their slowest cases haven’t closed yet.
Median days to close covers closed cases only — read it alongside the other two views for exactly that reason. Open-case backlog age is the median time the still-open requests have already waited, often the sharper equity story.
Source: City of Chicago 311 service requests (open data). Each request is placed in its community area and ward by the City’s own recorded assignment. See methodology for the window, freshness, and suppression details. Community areas with too few requests show as “insufficient data” rather than a noisy number.
