Is Gas At An All-Time High? Not Even Close
However, gas prices as a percent of income are still way below the early 1980s. In both 1980 and 1981, 1000 gallons of gas at the average price cost 14.1% of per-capita disposable personal income in those years. Gas prices averaged $1.245 and $1.38 in 1980 and 1981 respectively, and per-capita income was $8,822 and $9,765 in those years (see chart above, click to enlarge; source for Personal Income is Bureau of Economic Analysis, Table 2).
Gas is now selling for an average of $3.22 and per-capita disposable personal income in March was about $33,000, so that 1000 gallons of gas now costs 9.76% of per-capita personal disposable income (see chart above, click to enlarge).
