The Consumer Price Index for All Urban Consumers (CPI-U) in the Detroit-Ann Arbor-Flint area declined 1.0 percent from June to August, the U.S. Bureau of Labor Statistics reported today. Regional Commissioner Charlene Peiffer noted that the energy index decreased 6.1 percent while the food index edged up 0.1 percent over the bi-monthly period. The index for all items less food and energy declined 0.4 percent from June to August. Among the indexes within the all items less food and energy category, prices were lower for airline fares, recreation, and household furnishings and operations. (Data in this report are not seasonally adjusted. Accordingly, month-to-month changes may reflect the impact of seasonal influences.)
Over the past 12 months the Detroit all items CPI-U rose 1.0 percent. (See chart 1 and table A.) The energy index fell 1.6 percent over the year due to annual declines in prices for gasoline and electricity. The index for all items less food and energy rose 1.3 percent over the year. (See table 1.)
Food prices edged up 0.1 percent from June to August following a 0.5-percent decline over the previous bi-monthly period. Between the two components of the food index, prices for food at home (groceries) fell 0.4 percent and prices for food away from home (restaurant, cafeteria, and vending purchases) were higher by 0.8 percent. Grocery prices were up 1.7 percent from August a year ago, while prices for food away from home were 2.4 percent higher. From August 2013 to August 2014, overall food prices rose 2.0 percent in the Detroit area.
The energy index for Detroit fell 6.1 percent from June to August. Declines in the categories for gasoline (-10.5 percent) and utility (piped) gas service (-0.9 percent) were contributing factors. Electricity costs edged up 0.2 percent from June to August.
From August 2013 to August 2014, overall energy prices decreased 1.6 percent. Prices for gasoline and electricity fell 4.6 percent and 1.7 percent, respectively, over the year. In contrast, costs for utility (piped) gas service were up 7.1 percent compared to last August.
The index for all items less food and energy fell 0.4 percent from June to August. Among the index’s components, prices were lower for airline fares, recreation (-1.6 percent), and household furnishings and operations (-2.2 percent). In contrast prices for education and communication rose 1.8 percent from June to August.
Over the year, the index for all items less food and energy rose 1.3 percent. Annual increases in costs for shelter (3.2 percent) and education and communication (4.4 percent) were contributing factors.

The October 2014 Consumer Price Index for Detroit is scheduled to be released on Thursday, November 20, 2014, at 8:30 a.m. (ET).
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 88 percent of the total population and (2) a CPI for Urban Wage Earners and Clerical Workers (CPI-W) which covers 29 percent of the total 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 87 urban areas across the country from about 4,000 housing units and approximately 26,000 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 (1982-84) that equals 100.0. An increase of 16.5 percent, for example, is shown as 116.5. This change can also be expressed in dollars as follows: the price of a base period "market basket" of goods and services in the CPI has risen from $10 in 1982-84 to $11.65. For further details see the CPI home page on the Internet at www.bls.gov/cpi and the BLS Handbook of Methods, Chapter 17, The Consumer Price Index, available on the Internet at www.bls.gov/opub/hom/homch17_a.htm.
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-Ann Arbor-Flint, Mich. consolidated area covered in this release is comprised of Genesee, Lapeer, Lenawee, Livingston, Macomb, Monroe, Oakland, St. Clair, Washtenaw, and Wayne Counties in Michigan.
