The average price of gasoline fell 15.4% in the 12 months ended September compared to the 16.8% decline in August, according to the most recent inflation data published October 13, 2020 by the U.S. Labor Department’s Bureau of Labor Statistics (BLS).
Gasoline is an important category reported within the BLS’s monthly report on consumer inflation, the Consumer Price Index (CPI). "Gasoline (all types)" is listed as a subcategory under the overall "Energy" index for commodities.
The above chart shows some of the most important figures reported in the latest CPI report. Gasoline inflation as a component of the CPI’s "all items" index is a part of the data set used in calculating inflation rates. However, because gas prices tend to be more volatile, they along with food prices are stripped out when calculating core inflation rates.
This chart shows U.S. gasoline inflation on an annual basis over the last decade:
*For 2020, the most recent monthly inflation data (12-month based) is displayed in the chart.
