Hidalgo County covers a massive 1,583 square miles, making voter accessibility a constant logistical hurdle for organizing efforts. When a voter is motivated, they will vote. But when a voter is newly registered or on the fence, friction—such as distance to a polling site—acts as a significant deterrent.
This analysis calculates the straight-line geographic drive distance (Haversine formula approximation) from the center of every precinct to the exact coordinates of its nearest Early Voting polling location. The goal is to identify "Access Deserts"—high population areas where voters face the highest friction to cast a ballot before Election Day.
Interactive Accessibility Map
The map below visualizes these distances along with the actual turnout. Darker red precincts have the longest trips to an early voting location. The blue radial circles represent the early voting location itself, with the size of the circle corresponding to the total number of ballots cast at that location during the 2024 General Election.
The Distance Penalty: Top 10 EV Deserts
We ranked all precincts by their geographic distance to the nearest Early Voting center. The northernmost rural sectors of the county naturally top the list. For these precincts, getting out the vote requires targeted transportation efforts rather than just digital nudges.

Strategic Recommendation for Precinct Chairs
For precincts located more than 7 miles from an early voting site, standard phone banking scripts must shift their primary call-to-action to Election Day voting—or proactively offer transportation coordination if voting early is essential. Attempting to drive high early voting numbers in these specific zones without addressing the logistical friction will yield low conversion rates.
