Prices in the Midwest Region, as measured by the Consumer Price Index for All Urban Consumers (CPI-U), advanced 0.2 percent in May, the U.S. Bureau of Labor Statistics reported today. (See table A.) The May increase was largely influenced by higher prices for all items less food and energy, which rose 0.2 percent. The food index and energy index were also both up 0.2 percent.  (Data in this report are not seasonally adjusted. Accordingly, month-to-month changes may reflect seasonal influences.)

Over the last 12 months, the CPI-U increased 2.7 percent. (See chart 1.) The index for all items less food and energy advanced 3.0 percent and the food index rose 1.5 percent. Energy prices were up 1.4 percent, largely the result of increasing prices for electricity. (See table 1.)

Food prices rose 0.2 percent for the month of May. Prices for food away from home (restaurant, cafeteria, and vending purchases) increased 0.3 percent, and prices for food at home (grocery store prices) advanced 0.1 percent for the same period. Within the index for food at home, cereals and bakery products had the largest influence on the rise, up 0.6 percent over the month.

The food index rose 1.5 percent over the year, largely the result of increasing prices for food away from home (+3.4 percent). The index for food at home advanced 0.4 percent, led by an advance in the nonalcoholic beverages and beverage materials index (+2.9 percent). Somewhat offsetting grocery store price increases, the index for fruits and vegetables declined 2.2 percent in the same period.

The energy index was up 0.2 percent over the month, mainly due to higher prices for electricity (+1.9 percent), but rising natural gas service prices also contributed (+0.3 percent). Decreasing prices for gasoline (-0.6 percent) mostly offset rising prices in the other categories over the same period.

From May 2023 to May 2024, the energy index advanced 1.4 percent, largely due to higher prices for electricity (+5.0 percent). The index for gasoline fell 0.2 percent, and prices for natural gas service declined 3.2 percent during the past year.

The index for all items less food and energy rose 0.2 percent in May. Higher prices for shelter (+0.8 percent), public transportation, other goods and services (+0.3), and used cars and trucks (+0.5 percent) were largely offset by lower prices for recreation (-0.9 percent), household furnishings and operations (-0.4 percent), and apparel (-0.4 percent).

Over the year, the index for all items less food and energy advanced 3.0 percent. The main contributors to the increase included owners’ equivalent rent of residences (+6.5 percent), rent of primary residence (+6.1 percent), and medical care (+2.5 percent). Partly offsetting the increases were price decreases in used cars and trucks (-8.8 percent) and household furnishings and operations (-3.4 percent).

The June 2024 Consumer Price Index for the Midwest Region is scheduled to be released on Thursday, July 11, 2024.

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, 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 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 Midwest region is comprised of Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, and Wisconsin.
