Nationscape Data Set

December 2021

Democracy Fund + UCLA Nationscape is a partnership between Democracy Fund Voter Study Group and UCLA Political Scientists Chris Tausanovitch and Lynn Vavreck. It is one of the largest public opinion survey projects ever conducted — interviewing people in nearly every county, congressional district, and mid-sized U.S. city in the leadup to the 2020 election. Nationscape was fielded by Lucid, a market research platform that provides access to authentic, targeted audiences.

Phase 1 of the data, released in January of 2020, includes nearly 156,000 cases collected over 24 weeks. Data collection began with the week of July 18, 2019 and concluded the week of December 26, 2019 (last interview on January 1, 2020).

Phase 2 of the data, released in September of 2020, includes a re-release of Phase 1 data and new data from January 2020 to July 2020 (Phase 2 data).

Phase 3 of the data, released in December 2021, includes a re-release of Phase 1 and Phase 2 data and new data from August 2020 to February 2021 (Phase 3 data). This release also contains data from three additional data collections that ran concurrently with weekly surveys on April 2–-11, 2020, and July 15–-25, 2020; and also one additional effort after the Capitol was attacked, January 21–-February 3, 2021. The inclusion of these parallel data collections alongside weekly waves brings the total cases to 494,796.
