Prices in the St. Louis area, as measured by the Consumer Price Index for All Urban Consumers (CPI-U), increased 0.8 percent for the two months ending in December 2021, the U.S. Bureau of Labor Statistics reported today. Regional Commissioner Michael Hirniak noted that a 0.7-percent increase in the index for all items less food and energy was the leading factor in the rise, but higher prices for energy and food also contributed. (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 8.3 percent. (See chart 1.) The index for all items less food and energy increased 6.3 percent over the year. Energy prices jumped 34.1 percent, largely the result of an increase in the price of gasoline. The food index advanced 8.3 percent. (See table 1.)

Food

Food prices rose 0.6 percent for the two months ending in December. The index for food at home (grocery store prices) increased 1.1 percent, mainly due to price increases for fruits and vegetables. Prices for food away from home (restaurant, cafeteria, and vending purchases) were unchanged for the same period.

During the 12 months ending in December 2021, food prices increased 8.3 percent. Prices for food away from home jumped 11.0 percent, and prices for food at home advanced 6.2 percent since a year ago.

Energy

The energy index rose 2.5 percent for the two months ending in December. The increase was almost entirely due to higher prices for natural gas service (+16.1 percent). Prices for electricity increased 1.3 percent, while prices for gasoline decreased 0.6 percent for the same period.

Energy prices jumped 34.1 percent over the year, largely due to higher prices for gasoline (+56.7 percent), but all components contributed. Prices paid for natural gas service jumped 31.5 percent, and prices for electricity advanced 7.5 percent during the past year.

All items less food and energy

The index for all items less food and energy advanced 0.7 percent in November and December, after rising 1.1 percent in September and October. Higher prices for owners’ equivalent rent of residences (+1.4 percent), new and used motor vehicles (+3.6 percent), and recreation (+2.2 percent) were partially offset by lower prices for apparel (-3.7 percent), rent of primary residence (-0.7 percent) and other goods and services (-1.0 percent).

Over the year, the index for all items less food and energy increased 6.3 percent. Components contributing to the increase included shelter (+5.4 percent), new and used motor vehicles (+20.1 percent), and household furnishings and operations (+6.6 percent).

The February 2022 Consumer Price Index for the St. Louis area is scheduled to be released on Thursday, March 10, 2022.

Technical Note

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.
