The study was conducted by the Center for Responsive Politics, a non-partisan, non-profit research organization that tracks money in U.S. politics.
The study analyzed data from the Federal Election Commission (FEC) and the Internal Revenue Service (IRS) to identify the political contributions made by individuals and organizations at the county level. The data was then organized by political party and compared across counties.
The data used in the study is from the 2020 election cycle, which includes contributions made from January 1, 2019 to December 31, 2020.
No, the study includes data on contributions to both major political parties in the United States, the Democratic and Republican parties.
The study found that there is a correlation between certain demographic factors, such as income and education levels, and political contributions. Counties with higher income and education levels tend to contribute more to political campaigns, and there are also variations in contribution patterns based on race and ethnicity. However, the study does not provide a definitive explanation for these findings and more research is needed to fully understand the relationship between demographics and political contributions.
