Ethnic Collective Action in Contemporary Urban United States -- Data on Conflicts and Protests, 1954-1992 (ICPSR 34341)
This project seeks to identify sources of ethnic and racial conflict and protest in urban America from 1954 through 1992. The data on collective events are coded using The New York Times. Detailed coding rules produced a chronological dataset that allows researchers to:
Analyze the location and timing of both conflicts (confrontations between two or more ethnic populations) and protests (marches, mass meetings, demonstrations on behalf of one ethnic group, expressing grievances related to discrimination or racial policy).
Specifically analyze a type of protest (e.g., civil rights movement activity, or urban race riots) and the potential dynamic relationship of different types of protests and conflicts.
Identify any ethnic, nationality, or racial characteristics of participants who were the targets and/or instigators of each protest and conflict.
Analyze information on each event's location, size, targets, police presence, arrests, damage or injuries, and the content of claims directed against government authorities, police, and other groups.

#MeToo Tweet IDs, October 15-28, 2017 (ICPSR 37447)
This collection of tweet IDs pertains to the first two weeks of the #MeToo hashtag campaign in October 2017. During this time period there were over 1.5 million tweets with the #MeToo hashtag. Tweets containing the hashtag #MeToo were collected retroactively from a full historical Twitter Firehose (100%) collection, and reply threads in response to those tweets were separately collected from Twitter. According to Twitter Terms of Service, full tweet objects cannot be disseminated, but the tweet IDs can be rehydrated through Twitter's public GET statuses/lookup API endpoint.
The available data for this study exist in one zipped folder containing 28 files. There are 14 .csv files, one for each day, between October 15th to October 28th, containing the tweet ID with one tweet ID appearing per line. Each file only contains a single column of data (tweet_id). There were on average 109,237 tweets per day during this two-week period ranging between 16,074 to 528,143 tweets per day. Tweets must have been public and not deleted or taken down at the time of collection in order to appear in this dataset.
The other 14 .csv files correspond to the reply threads for each day in response to tweets containing the hashtag #MeToo. Each line indicates the tweet ID of a reply in a thread of replies to a #MeToo tweet (tweet_id) and the tweet ID of the tweet immediately preceeding that tweet in the reply thread (in_reply_to_tweet_id) as comma-separated values. There were on average 21,072 replies to tweets per day during this period with a range of 2,388 to 110,789 replies per day.
