   Harvard Dataverse (Erica Chenoweth and Jeremy Pressman). Crowd Counting Consortium. (2018). The Crowd Counting Consortium's public data repository, where its event-level records of US protests are published monthly. This is a repository landing page listing datasets, not a document, and it could not be read: dataverse.harvard.edu sits behind an AWS WAF challenge that returns HTTP 202 with an empty body to non-browser clients, and the Wayback Machine holds no successful capture of it. No claim in this entry rests on it. A superseded note credited it with 'the number of March for Our Lives locations on 24 March 2018 and the participation range' — figures this entry does not state and which a collection landing page could not carry in any case.

   Ash Center for Democratic Governance and Innovation, Harvard Kennedy School. Crowd Counting Consortium. (2018). The consortium's own programme page: a joint Harvard Kennedy School and University of Connecticut project, begun by Jeremy Pressman and Erica Chenoweth to count participants in the January 2017 Women's March, that collects publicly available data on US protest events. Source for the scale figure used here: 'CCC data were used to demonstrate that, at that time, the 2018 March for Our Lives and #Enough Walkouts were the broadest single day demonstration if U.S. history (occurring in over 4400 distinct locations)' — a combined figure for the march and the walkouts, not for the march alone. A superseded note credited this page with describing the consortium's method and why its estimates are ranges; it does neither, and the words 'range' and 'method' do not appear on it.
