Boston 311 Service Requests (2025)
A year of Bostonians asking the city for help — every 311 service request from 2025, with type, neighborhood, and resolution timestamps.
Every 311 service request made to the City of Boston during 2025: request type, opened/closed timestamps, neighborhood, source channel, and outcome. Self-hosted copy of the export from Analyze Boston, the city’s open data portal.
This is the course’s flagship “real, messy, civic” dataset — big enough that you feel the size, real enough that every analysis suggests a policy question. Missing values, inconsistent categories, and timestamp quirks included, free of charge.

Citing this dataset
Course style guide rule: cite the dataset name, provider, and the date you accessed it — e.g. "Boston 311 Service Requests (2025). Course data catalog, courses.langd0n.com. Accessed [date]." If the entry names an upstream source (a city portal, a public agency), cite that too.
