AAA publishes a daily county average behind the county map on each state page; this reads that payload for all 50 states and joins it to Census county FIPS. The District of Columbia is a single county-equivalent, so its district-wide average is its county figure.
AAA covers only Anchorage and Mat-Su in Alaska. The other 8 boroughs shown come from the Alaska DCCED community fuel survey, aggregated to borough and drawn with a dashed outline — that survey is semi-annual rather than daily.
3,089 of 3,142 county-equivalents carry a price (98.3%). The remaining 53 are hatched: almost all are among the least populated counties in the country, where no survey reports a pump price.
The history behind the chart is 431,263 observations across 3,128 counties and 140 dates, 2020-04-06 to 2026-11-02. Everything before 2026-11-02 was reconstructed from archived copies of AAA’s county payload, sampled one capture per state-week; each daily refresh adds a point from here on.
