The average price of gasoline dropped 5.4% in the 12 months ended June as compared to the 0.2% decrease in May, according to the most recent inflation data published July 11, 2019 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 most recent CPI report. Gasoline inflation is a component of the CPI’s "all items" index, as well as the Energy index of course, and so they are part of the data set that is used in calculating inflation rates. Because gas prices tend to be more volatile, they are stripped out when calculating core inflation rates.
This chart shows U.S. gasoline inflation on an annual basis over the last decade:
*For 2019, the most recent inflation monthly data (12-month based) is displayed in the chart.
