The Consumer Price Index for All Urban Consumers (CPI-U) in the Detroit-Ann Arbor-Flint area rose 0.1 percent from October to December, the U.S. Bureau of Labor Statistics reported today. Assistant Commissioner for Regional Operations Charlene Peiffer noted that over the bi-monthly period the food index and energy index rose 0.4 percent and 2.0 percent, respectively, while the index for all items less food and energy decreased 0.2 percent. Among the indexes within the all items less food and energy category, prices were lower for apparel, shelter, and recreation. (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 increased 2.7 percent. (See chart 1 and table A.) The food index and the energy index rose 2.0 percent and 3.6 percent, respectively, from December 2016 to December 2017. The index for all items less food and energy rose 2.7 percent over the year. (See table 1.)
Food prices rose 0.4 percent from October to December. Of the two components within the food index, prices for food at home (groceries) increased 0.2 percent and prices for food away from home (restaurant, cafeteria, and vending purchases) were 0.8 percent higher.
Over the year, food prices in the Detroit area were up 2.0 percent. Prices for groceries and food away from home rose 0.8 percent and 3.8 percent, respectively, from December 2016.
The energy index for Detroit was 2.0 percent higher from October to December, primarily due to gasoline prices rising 2.8 percent. Electricity prices increased 1.1 percent, while utility (piped) gas service costs declined 0.3 percent.
From December 2016 to December 2017, overall energy prices rose 3.6 percent. Gasoline prices increased 11.7 percent over the year. In contrast, the electricity and utility (piped) gas service indexes declined 6.1 percent and 1.5 percent, respectively.
The index for all items less food and energy decreased 0.2 percent from October to December. Among the index’s components, prices were lower for apparel (-6.5 percent), shelter (-0.4 percent), and recreation (-1.8 percent). Prices were higher for new and used motor vehicles and medical care (0.6 percent).
Over the year, the index for all items less food and energy rose 2.7 percent. A 5.4-percent increase in the index for shelter was a major contributing factor.
The February 2018 Consumer Price Index for Detroit is scheduled to be released on Tuesday, March 13, 2018.
In January 2018, BLS will introduce a new geographic area sample for the Consumer Price Index (CPI). As part of the new sample, the index for this area will be renamed. The first indexes using the new structure will be published in February 2018. Additional information on the geographic revision is available at: www.bls.gov/cpi/additional-resources/geographic-revision-2018.htm.
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 89 percent of the total population and (2) a CPI for Urban Wage Earners and Clerical Workers (CPI-W) which covers 28 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 6,000 housing units and approximately 24,000 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/pdf/homch17.pdf.
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.
