The index that serves as the standard measure of inflation rose 2.2 percent in Boston over the past year, the federal government announced Friday.

The Consumer Price Index in the Boston metropolitan area edged up 0.1 percent during the two months ending July 2017, with higher prices for food and shelter almost offset by a decrease in energy prices, according to the U.S. Bureau of Labor Statistics, which tracks prices of goods and services.

Looking back over the past year, local consumers coped with energy prices that were up 7.2 percent and food prices that rose 1.5 percent over the year. In the energy realm, electricity prices in the Boston area were up 9.7 percent over the past year. Restaurant prices are up 2.2 percent since July 2016.

There are seven metropolitan areas for which inflation measures are available this month. Among those, Boston was tied with the Chicago area for the second-highest annual rate of CPI growth. Prices increased over the past year by 2.5 percent in Los Angeles.

According to the BLS, the CPI is based on prices of food, clothing, shelter, fuels, transportation fares, charges for doctors’ and dentists’ services, drugs and the other goods and services that people buy for day-to-day living.
