Prices in the St. Louis area, as measured by the Consumer Price Index for All Urban Consumers (CPI-U), increased 0.3 percent for the two months ending in December 2024, the U.S. Bureau of Labor Statistics reported today. Assistant Commissioner of Regional Operations Michael Hirniak noted that the index for all items less food and energy advanced 0.4 percent. The energy index rose 0.6 percent, led by higher prices for electricity. The index for food fell 0.1 percent over the two-month period. (Data in this report are not seasonally adjusted. Accordingly, bi-monthly changes may reflect seasonal influences.)

Over the last 12 months, the CPI-U advanced 3.1 percent. The index for all items less food and energy increased 3.4 percent, largely due to a rise in index for shelter over the year. The index for food was up 2.3 percent, and the index for energy rose 1.5 percent over the same period. (See chart 1 and table 1.)

Food prices decreased 0.1 percent for the two months ending in December. Prices for food at home (grocery store prices) were down 0.4 percent; declines were led by the indexes for other food at home (-1.4 percent) and cereals and bakery products (-2.2 percent). The food away from home index (restaurant, cafeteria, and vending purchases) increased 0.3 percent for the same period.

Over the year, food prices rose 2.3 percent. Prices for food away from home advanced 4.1 percent since a year ago. Prices for food at home increased 1.1 percent, led by a rise in the indexes for fruits and vegetables (+3.0 percent) and meats, poultry, fish, and eggs (+1.7 percent).

The energy index was up 0.6 percent for the two months ending in December. The increase was entirely due to a rise in the price for electricity (+4.7 percent). Partly offsetting the rise, the index for natural gas service fell 2.2 percent, and the index for gasoline declined 0.7 percent for the same period.

From December 2023 to December 2024, energy prices advanced 1.5 percent, led by an increase in the index for electricity (+3.6 percent). Prices paid for natural gas service rose 5.7 percent, while prices paid for gasoline declined 0.4 percent during the past year.

The index for all items less food and energy increased 0.4 percent in the latest two-month period. Higher prices for public transportation, medical care (+1.9 percent), and owners’ equivalent rent of residences (+0.5 percent) were partially offset by lower prices for apparel (-5.8 percent), lodging away from home, and recreation (-0.6 percent).

Over the year, the index for all items less food and energy increased 3.4 percent. Components contributing to the increase included owners’ equivalent rent of residences (+5.9 percent), medical care (+5.6 percent), and rent of primary residence (+7.5 percent). Partly offsetting the increases were price decreases in education and communication (-3.9 percent), apparel (-4.3 percent), and new and used motor vehicles (-1.4 percent).

The February 2025 Consumer Price Index for the St. Louis area is scheduled to be released on Wednesday, March 12, 2025.

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.
