+# DIME: Database on Ideology, Money in Politics, and Elections (Parquet Format)
+
+This dataset is a Parquet conversion of the [Database on Ideology, Money in Politics, and Elections (DIME)](https://data.stanford.edu/dime) Public version 4.0, originally compiled by Adam Bonica at Stanford University.
+
+## Dataset Description
+
+The DIME database provides a comprehensive resource for the study of campaign finance and ideology in American politics. It contains over **850 million itemized political contributions** made by individuals and organizations to local, state, and federal elections from 1979 to 2024.

+### Key Features
+
+- **Data Processing:** Names, addresses, occupation, and employer titles have been cleaned and standardized
+- **Unique Identifiers:** Entity resolution assigns unique IDs for all donors, enabling tracking across election cycles and government levels
+- **Geocoding:** Records are geocoded and placed into congressional districts
+- **Ideological Measures:** Common-space DIME scores (CFscores) allow direct comparison of ideal points across political actors
+- **Candidate/Committee Data:** Includes fundraising statistics, election outcomes, gender, and other characteristics
+
+### Coverage
+
+- **Time Span:** 1979-2024
+- **Geographic Coverage:** United States (local, state, and federal elections)
+- **Records:** 850M+ itemized contributions, 156K+ candidates, 37K+ committees, 36M+ individual donors
