Consumer Price Index, Chicago-Naperville-Elgin — June 2018

Local prices rose 2.2 percent over the year

The Consumer Price Index for All Urban Consumers (CPI-U) in the Chicago-Naperville-Elgin area fell 0.2 percent in June, the U.S. Bureau of Labor Statistics reported today. Assistant Commissioner for Regional Operations Charlene Peiffer noted that the energy index decreased 1.0 percent while food prices rose 0.5 percent in June. The all items less food and energy index declined 0.2 percent over the month. Within the all items less food and energy category, prices were lower for recreation and apparel. The shelter index rose over the month. (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 2.2 percent. (See chart 1 and table A.) Over the year, the energy index rose 11.0 percent. The rise in the energy index was primarily due to higher gasoline prices. Both the food index and the all items less food and energy index were up 1.6 percent over the year. (See table 1.)

Food

Food prices increased 0.5 percent in June. The food at home index (groceries) rose 0.5 percent, while the food away from home (restaurant, cafeteria, and vending purchases) index increased 0.6 percent. Within the food at home group, indexes were higher in June for uncooked beef steaks; other pork including roasts and picnics; and citrus fruits. Prices were lower for eggs and bacon, breakfast sausage and related products.

From June 2017 to June 2018, the food index increased 1.6 percent. Over the year, costs for food away from home rose 3.6 percent, while grocery prices were 0.1 percent lower.

Energy

The energy index declined 1.0 percent in June, primarily due to a 2.2-percent decrease in gasoline prices. Utility (piped) gas service costs fell 2.2 percent and electricity costs increased 2.5 percent in June.

Over the year, the Chicago area energy index rose 11.0 percent. From June 2017 to June 2018, gasoline prices rose 26.8 percent. The utility (piped) gas service index and the electricity index declined 7.7 percent and 0.4 percent, respectively, over the year.

All items less food and energy

The index for all items less food and energy declined 0.2 percent in June. Among the index’s components, prices were lower for recreation (-1.1 percent) and apparel (-1.6 percent) but higher for shelter (0.3 percent).

Over the year, the index for all items less food and energy rose 1.6 percent. A 4.0-percent increase in the index for owners’ equivalent rent of primary residence was the major contributing factor.

The July 2018 Consumer Price Index for Chicago is scheduled to be released on Friday, August 10, 2018.


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 93 percent of the total population and (2) a CPI for Urban Wage Earners and Clerical Workers (CPI-W) which covers approximately 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 75 urban areas across the country from about 5,000 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 (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.
