Consumer Price Index, Chicago-Gary-Kenosha — May 2017

Local prices up 1.8 percent over the year

The Consumer Price Index for All Urban Consumers (CPI-U) in the Chicago-Gary-Kenosha area increased 0.2 percent in May, the U.S. Bureau of Labor Statistics reported today. Assistant Commissioner for Regional Operations Charlene Peiffer noted that food prices increased 0.9 percent and energy prices were down 2.0 percent in May. The all items less food and energy index increased 0.2 percent over the month. Among the indexes within the all items less food and energy category, prices were higher for shelter and medical care. (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 increased 1.8 percent. (See chart 1 and table A.) Energy costs rose 3.9 percent over the year, primarily due to an increase in the index for utility (piped) gas service. The all items less food and energy index was 1.9 percent higher over the year. (See table 1.)

Food

Food prices rose 0.9 percent in May mostly due to a 1.4-percent increase in the food at home index (groceries). The food away from home index, which includes restaurant, cafeteria, and vending purchases, rose 0.2 percent. Within the food at home group, indexes were higher in May for carbonated drinks, pork chops, and flour and prepared flour mixes.

From May 2016 to May 2017, the food index increased 0.4 percent. Food away from home prices rose 2.0 percent over-the-year, while grocery prices were down 0.6 percent compared to May a year ago.

Energy

The energy index fell 2.0 percent in May primarily due to a 4.5-percent drop in gasoline prices. To a lesser extent, a 0.5-percent decline in the index for electricity also contributed. Utility (piped) gas service costs were up 1.7 percent in May.

Over the year, the Chicago area energy index rose 3.9 percent. Utility (piped) gas service costs rose 23.8 percent and were responsible for most of this increase. Gasoline prices were up 1.5 percent compared to May 2016 and the electricity index declined 3.1 percent on an annual basis.

All items less food and energy

The index for all items less food and energy increased 0.2 percent in May. Among the index’s components, prices were higher for shelter (0.7 percent) and medical care (0.5 percent). Recreation prices fell 1.8 percent over-the-month and apparel costs were down 0.8 percent compared to April.

Over the year, the index for all items less food and energy increased 1.9 percent. Increases in the indexes for shelter (2.9 percent) and medical care (4.0 percent) were major contributing factors.

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.
