Food prices fell 0.3 percent for the month of June. Prices for food at home (groceries) declined 0.5 percent, and prices for food away from home (restaurant, cafeteria, and vending purchases) were unchanged for the same period. Within the food at home group, indexes were lower in June for citrus fruits, other fresh vegetables, and coffee. In contrast the indexes for other miscellaneous foods (includes easy-to-prepare canned or non-frozen packaged foods excluding fruits, vegetables or soups), canned fruits and vegetables, and fresh fish and seafood were higher.

Over the year, food prices advanced 3.3 percent. Prices for food at home advanced 2.4 percent over the year. Four of the six major grocery store food group indexes advanced over the year. The index for other food at home (includes sugar, sweets, fats, and oils, for example) rose 5.4 percent, cereals and bakery products advanced 5.1 percent, and nonalcoholic beverages and beverage materials increased 4.6 percent. Prices for food away from home rose 4.8 percent.

The energy index decreased 1.5 percent over the month. The decrease was mainly due to lower prices for electricity (-6.6 percent). Prices for gasoline increased 2.1 percent, while prices for utility (piped) gas service fell 2.2 percent for the same period.

Energy prices decreased 23.3 percent over the year, largely due to lower prices for gasoline (-25.9 percent). Prices paid for electricity advanced 14.4 percent, while prices for utility (piped) gas service declined 45.7 percent during the past year.

The index for all items less food and energy advanced 0.3 percent in June. Higher prices for shelter (0.6 percent) and new and used motor vehicles (0.5 percent) were partially offset by lower prices for recreation (-0.8 percent) and education and communication (-0.6 percent).

Over the year, the index for all items less food and energy increased 5.1 percent. Components contributing to the increase included shelter (7.1 percent) and recreation (12.0 percent).

The July 2023 Consumer Price Index for the Chicago-Naperville-Elgin area is scheduled to be released on Thursday, August 10, 2023.

The Consumer Price Index for Chicago is published monthly. The Consumer Price Index (CPI) is a measure of the average change in prices over time in a fixed market basket of goods and services. The Bureau of Labor Statistics publishes CPIs for two population groups: (1) a CPI for All Urban Consumers (CPI-U) which covers approximately 93 percent of the total population and (2) a CPI for Urban Wage Earners and Clerical Workers (CPI-W) which covers 29 percent of the total population. The CPI-U includes, in addition to wage earners and clerical workers, groups such as professional, managerial, and technical workers, the self-employed, short-term workers, the unemployed, and retirees and others not in the labor force.

The CPI is based on prices of food, clothing, shelter, and fuels, transportation fares, charges for doctors' and dentists' services, drugs, and the other goods and services that people buy for day-to-day living. Each month, prices are collected in 87 urban areas across the country from about 4,000 housing units and approximately 26,000 retail establishments--department stores, supermarkets, hospitals, filling stations, and other types of stores and service establishments. All taxes directly associated with the purchase and use of items are included in the index.

The index measures price changes from a designated reference date (1982-84) that equals 100.0. An increase of 16.5 percent, for example, is shown as 116.5. This change can also be expressed in dollars as follows: the price of a base period "market basket" of goods and services in the CPI has risen from $10 in 1982-84 to $11.65. For further details see the CPI home page on the Internet at www.bls.gov/cpi and the BLS Handbook of Methods, Chapter 17, The Consumer Price Index, available on the Internet at www.bls.gov/opub/hom/homch17_a.htm.

In calculating the index, price changes for the various items in each location are averaged together with weights that represent their importance in the spending of the appropriate population group. Local data are then combined to obtain a U.S. city average. Because the sample size of a local area is smaller, the local area index is subject to substantially more sampling and other measurement error than the national index. In addition, local indexes are not adjusted for seasonal influences. As a result, local area indexes show greater volatility than the national index, although their long-term trends are quite similar. Note:Area indexes do not measure differences in the level of prices between cities; they only measure the average change in prices for each area since the base period.
