About

This analysis examines geographic gaps in public electric vehicle charging infrastructure across the United States. Using validated data from 81,428 active stations with 253,672 public charging ports, we compare infrastructure density against EV registration demand and state demographics to identify underserved regions and market segments. Key finding: while the national average of 74 ports per 100,000 residents exceeds the median state benchmark of 55 ports per 100,000, half of all states fall below this threshold, indicating sharp geographic inequality in charging access.
