The Chicago-Naperville-Elgin Consumer Price Index for All Urban Consumers (CPI-U), was unchanged in June, the U.S. Bureau of Labor Statistics reported today. (See table A.) Regional Commissioner Jason Palmer noted that the indexes for shelter, other goods and services, and education and communication increased in June. Indexes for apparel and recreation were lower. (Data in this report are not seasonally adjusted. Accordingly, month-to-month changes may reflect the impact of seasonal influences.)

Over the last 12 months, the CPI-U increased 3.0 percent. (See chart 1 and table A.) The index for all items less food and energy rose 3.4 percent over the year. Food prices increased 1.9 percent. Energy prices fell 0.2 percent, largely the result of a decrease in the price of gasoline. (See table 1.)

Food prices increased 0.1 percent for June. The food at home index (groceries) was unchanged, and the food away from home index (restaurant, cafeteria, and vending purchases) rose 0.2 percent for the same period. Within the food-at-home group, categories experiencing increases included snacks, other fresh vegetables, and uncooked other beef and veal. Indexes were lower for chicken, pork chops, and other dairy and related products.

Over the year, food prices increased 1.9 percent. The food at home index rose 1.7 percent as five of the six major grocery store food group indexes increased over the year. Increasing indexes included other food at home (includes sugar, sweets, fats, and oils, for example) (+2.1 percent), nonalcoholic beverages and beverage materials (+4.2 percent), cereals and bakery products (+3.1 percent), fruits and vegetables (+1.0 percent), and dairy and related products (+1.4 percent). Prices for food away from home advanced 2.2 percent.

The energy index declined 3.6 percent over the month. The decrease was mainly due to a decline in the electricity index (-9.5 percent). The index for utility (piped) gas service increased 3.2 percent, while gasoline prices declined 1.9 percent for the same period.

Energy prices fell 0.2 percent over the year, largely due to lower gasoline prices (-4.1 percent). The index for utility (piped) gas service rose 7.2 percent, and the electricity index advanced 1.1 percent during the past year.

The index for all items less food and energy rose 0.3 percent in June. Higher prices for shelter (+0.9 percent), other goods and services (+2.1 percent), and education and communication (+0.4 percent) were partially offset by lower prices for apparel (-4.2 percent) and recreation (-1.6 percent).

Over the year, the index for all items less food and energy rose 3.4 percent. Components contributing to the increase included shelter (+5.6 percent) and other goods and services (+12.2 percent).

The July 2024 Consumer Price Index for the Chicago-Naperville-Elgin area is scheduled to be released on August 14, 2024.

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 U.S. population and (2) a CPI for Urban Wage Earners and Clerical Workers (CPI-W) which covers approximately 29 percent of the total U.S. 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, 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 75 urban areas across the country from about 6,000 housing units and approximately 22,000 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; for most of the CPI-U the reference base is 1982-84 equals 100. An increase of 7 percent from the reference base, for example, is shown as 107.000. Alternatively, that relationship can also be expressed as the price of a base period market basket of goods and services rising from $100 to $107. For further details see the CPI home page on the internet at www.bls.gov/cpi and the CPI section of the BLS Handbook of Methods available on the internet at www.bls.gov/opub/hom/cpi/.

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.

The Chicago-Gary-Kenosha, IL-IN-WI Core Based Statistical Area includes Cook, DeKalb, DuPage, Grundy, Kane, Kendall, Lake, McHenry, and Will Counties in Illinois; Jasper, Lake, Newton, and Porter Counties in Indiana; and Kenosha County in Wisconsin.
