City of Boston (Analyze Boston) publishes 235 open datasets for United States. Browse them live in Vizzie and turn any one into a map or chart.
City of Boston (Analyze Boston) is the open-data portal for United States, covering Massachusetts. It runs on CKAN, an open catalogue standard used by many national governments. You can browse it directly at data.boston.gov.
On City of Boston (Analyze Boston), most datasets here are clearly licensed — only a small share are undeclared. It's important to know that "no licence declared" is not the same as public-domain or free-to-use. Undeclared data carries no explicit permission to copy, adapt, or redistribute it — so reusers should treat it cautiously and check with the publisher before relying on it. Vizzie flags each dataset's licence (or its absence) so you can see this before you build.
Of the 220 datasets here whose licence Vizzie can identify, essentially all of them can be used commercially; 0% carry a share-alike condition, so work built on them has to be published under the same terms. Attribution is required by almost every open licence — Vizzie writes the attribution line for you when you export or publish.
93% PDDL-1.0 (219/235), measured live 8 Sep 2026. The earlier reading of 230 UNDECLARED was an artefact of PDDL having no alias in this matrix, not the portal's own metadata.
