Consumer Price Index, Detroit-Warren-Dearborn area – August 2024

Area prices were up 0.8 percent over the past two months, up 3.5 percent from a year ago

Prices in the Detroit-Warren-Dearborn area, as measured by the Consumer Price Index for All Urban Consumers (CPI-U), increased 0.8 percent for the two months ending in August 2024, the U.S. Bureau of Labor Statistics reported today. (See table A.) Regional Commissioner Jason Palmer noted that the indexes for shelter, apparel, and education and communication were higher over the June-August period. The medical care index was lower. (Data in this report are not seasonally adjusted. Accordingly, bi-monthly changes may reflect seasonal influences.)

Over the last 12 months, the CPI-U rose 3.5 percent. (See chart 1 and table A.) The index for all items less food and energy rose 4.2 percent over the year. Energy prices declined 0.1 percent, and food prices increased 0.4 percent. (See table 1.)


Food

Food prices fell 0.7 percent for the two months ending in August. (See table 1.) The food at home index (groceries) declined 1.1 percent, and the food away from home index (restaurant, cafeteria, and vending purchases) increased 0.1 percent for the same period.

Over the year, food prices increased 0.4 percent. The food at home index decreased 0.8 percent since a year ago. Five of the six major grocery store food group indexes were lower over the year. The index for fruits and vegetables was down 2.6 percent; the index for other food at home (includes sugar, sweets, fats, and oils, for example) fell 0.4 percent; the index for meats, poultry, fish, and eggs decreased 1.1 percent; the dairy and related products index declined 0.7 percent; and the nonalcoholic beverages and beverage materials index decreased 0.2 percent. Prices for food away from home rose 2.8 percent over the year.

Energy

The energy index increased 0.2 percent for the two months ending in August. Gasoline prices rose 0.2 percent over the June-August period. For the same period, utility (piped) gas service prices increased 0.5 percent and electricity prices decreased 0.1 percent.

Energy prices declined 0.1 percent over the year. Gasoline prices fell 6.1 percent while electricity prices increased 4.8 percent, and prices for utility (piped) gas service rose 1.4 percent during the past year.

All items less food and energy

The index for all items less food and energy advanced 1.1 percent in the latest two-month period. Higher prices for shelter (+1.3 percent), apparel (+11.1 percent), and education and communication (+1.5 percent) were partially offset by lower prices for medical care (-1.4 percent).

Over the year, the index for all items less food and energy rose 4.2 percent. A 6.7 percent increase in the shelter index was a contributing factor.

The October 2024 Consumer Price Index for the Detroit-Warren-Dearborn area is scheduled to be released on November 13, 2024.


Technical Note

The Consumer Price Index for Detroit is published bi-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 atwww.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 Detroit-Warren-Dearborn, MI, Core Based Statistical Area includes Lapeer, Livingston, Macomb, Oakland, St. Clair, and Wayne Counties in Michigan.
