## What it is

US Voter Turnout maps participation across states and presidential election years. Visitors can move through the timeline, inspect state values, and compare each state's highest- and lowest-turnout presidential elections.

The interface offers two public data sources with different definitions and coverage. United States Elections Project data includes state-level voting-eligible-population turnout through 2024. Census Bureau tables report voting and registration percentages for voting-age and citizen voting-age populations through 2020. The source switch is preserved because the measures should not be presented as interchangeable.

Raw CSV and spreadsheet inputs are cleaned and normalized with Python and pandas, then served as static JSON to a D3.js map.
