How to read it: each call is a resident’s report to dispatch that police logged, placed at the hundred-block (for example “9XX 15th St”), not at a house; a call is not a finding that the law was broken. The one address that produced a tenth of the city’s calls from a single dispute is shown but flagged in the methods FAQ. Source: City of Boulder open data, NOISEB call type, downloaded Aug. 15, 2026.
