To identify the price of gas the year you were born, 24/7 Wall St. reviewed the inflation-adjusted annual average price of a gallon of regular gasoline (leaded pre-1990) from the U.S. Energy Information Administration’s May 2017 Monthly Energy Review (table 9.4).
The average price of a barrel of crude oil and annual gasoline consumption also came from the EIA. Annual U.S. crude oil imports and production also came from the EIA.
Per-capita gas consumption was calculated using population estimates from the U.S. Census Bureau. All inflation-adjusted prices are tied to 2016 dollars.
