About the data & dashboard
Crowd Counting Consortium · Phase 3 · January 2025 onward
The Crowd Counting Consortium (CCC) is a joint project of Harvard Kennedy School and the
University of Connecticut that collects publicly available data on political protest events
reported in the United States, including rallies, marches, demonstrations, and acts of civil
disobedience. This dashboard lets you explore that record: where events happened, when, what
they were about, and how many people took part.
CCC draws on a broad, continually updated set of sources: an automated crawl of print and
broadcast media; regular review of social media accounts run by organizers, activists and
independent journalists, which often surface events commercial outlets miss entirely; Google
News searches to catch what the crawler doesn't; periodic review of organizers' own websites
and calendars; and public submissions through CCC's
online form, added only once
the event is confirmed to have taken place.
Filters apply together, and the map, the figures above it and the charts on the right
update as one. Drag the handles under the date range to narrow the period. Numbered
circles group nearby events — click one to zoom in. When the ring around one turns teal,
every event inside it shares one exact location (including the territory panels along the
bottom), so zooming further won't separate them — click to open a list instead.
Individual points are coloured by political valence and sized by crowd size; hover one for its
date, size, claim and sources. The Legend button in the map's top-right corner explains these
symbols.
Reading the numbers
Crowd size is recorded for about 30% of events, and not at random —
larger, more widely covered gatherings are far more likely to have an estimate. The
participant total sums only those events; the coverage figure beside it shows what share of
the current selection it rests on.
Events are located to their city or town, not a street address, so many
events in the same place share identical coordinates.
Absence of events isn't evidence of absence. The record depends on what
the sources above surfaced. Know of something missing or wrong? CCC accepts corrections
through the submission form above.
Getting the data
The full dataset and its codebook are published openly on Harvard Dataverse, along with the
earlier phases covering 2017–2024, which are not shown here.
If you use the data in published work, please cite the Crowd Counting Consortium as the
