Incorrect prices for prescription drugs were used for the CPI-U and CPI-W indexes from May through August 2016 in a number of areas. Several indexes were affected, including the all items and medical care indexes. A list of the series affected can be found at www.bls.gov/bls/errata/cpi-price-corrections-10182016.htm, and the corrected data are available in the CPI database (www.bls.gov/cpi/data.htm).

Consumer Price Index, Chicago-Gary-Kenosha — July 2016

Local prices down 0.1 percent over the year

The Consumer Price Index for All Urban Consumers (CPI-U) in the Chicago-Gary-Kenosha area fell 0.8 percent in July, the U.S. Bureau of Labor Statistics reported today. Assistant Commissioner for Regional Operations Charlene Peiffer noted that energy prices declined 4.5 percent and food prices fell 0.3 percent in July. The all items less food and energy index decreased 0.6 percent over the month. Among the indexes within the all items less food and energy category, prices were lower for shelter, recreation, and apparel. (Data in this report are not seasonally adjusted. Accordingly, month-to-month changes may reflect the impact of seasonal influences.)

Over the last 12 months, the Chicago area all items CPI-U was down 0.1 percent. (See chart 1 and table A.) The energy index fell 12.2 percent over the year as prices declined for gasoline, electricity, and utility (piped) gas service. The all items less food and energy index was 1.1 percent higher over the year. (See table 1.)

Food

Food prices fell 0.3 percent in July following a 0.4-percent decrease in June. Between the two components within the food index, prices for food at home (groceries) decreased 0.6 percent, while prices for food away from home (restaurant, cafeteria, and vending purchases) were up 0.1 percent over the month. Within the food at home group, prices were lower for nonfrozen noncarbonated juices and drinks; breakfast cereal; and milk. In contrast, the indexes for tomatoes, potatoes, and lettuce increased.

From July 2015 to July 2016, the food index was unchanged. Prices for food eaten away from home rose 3.7 percent over the year, while grocery food prices fell 2.4 percent.

Energy

The energy index was down 4.5 percent in July primarily due to gasoline prices falling 11.5 percent. Utility (piped) gas service costs increased 5.0 percent over the month and the electricity index rose 1.1 percent.

Over the year, the Chicago area energy index declined 12.2 percent. The major contributing factor in the energy index’s decline was a 20.6-percent decrease in gasoline prices from July 2015. The electricity index fell 4.4 percent and utility (piped) gas service costs edged down 0.1 percent during the same period.

All items less food and energy

The index for all items less food and energy decreased 0.6 percent in July. Prices were lower for shelter (-0.5 percent), recreation (-2.3 percent), and apparel (-3.3 percent).

Over the year, the index for all items less food and energy increased 1.1 percent. Increases in the indexes for shelter (2.6 percent) and medical care (2.1 percent) were major contributing factors. In contrast, prices were down for household furnishings and operations (-4.1 percent), recreation (-2.3 percent), and apparel (-3.7 percent).

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 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 Chicago-Gary-Kenosha, Ill.-Ind.-Wis. consolidated area covered in this release is comprised of Cook, DeKalb, DuPage, Grundy, Kane, Kankakee, Kendall, Lake, McHenry, and Will Counties in Illinois; Lake and Porter Counties in Indiana; and Kenosha County in Wisconsin.
