The Consumer Price Index for All Urban Consumers (CPI-U) in the Chicago-Gary-Kenosha area rose 0.3 percent in August, the U.S. Bureau of Labor Statistics reported today. Assistant Commissioner for Regional Operations Charlene Peiffer noted that in August the food and energy indexes increased 0.8 percent and 1.1 percent, respectively. The all items less food and energy index edged up 0.1 percent over the month. Among the indexes within the all items less food and energy category, prices were higher for apparel and education and communication. (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 2.3 percent. (See chart 1 and table A.) Over the year, the food and energy indexes rose 1.1 percent and 6.9 percent, respectively. The all items less food and energy index was 2.1 percent higher over the year. (See table 1.)
Food prices rose 0.8 percent in August. The food at home index (groceries) increased 1.3 percent, while the food away from home (restaurant, cafeteria, and vending purchases) index was unchanged. Within the food at home group, indexes were higher in August for carbonated drinks, citrus fruits, and potatoes.
From August 2016 to August 2017, the food index increased 1.1 percent. Grocery prices rose 0.8 percent over the year, and food away from home prices rose 1.6 percent from August a year ago.
The energy index rose 1.1 percent in August, primarily due to a 2.8-percent increase in gasoline prices. Electricity costs rose 0.5 percent over the month. In contrast, utility (piped) gas service costs fell 1.8 percent.
Over the year, the Chicago area energy index rose 6.9 percent. From August 2016 to August 2017 gasoline prices rose 7.6 percent. Costs for electricity and utility (piped) gas service were up 6.7 percent and 6.1 percent, respectively over the year.
The index for all items less food and energy edged up 0.1 percent in August. Among the index’s components, prices were higher for apparel (2.5 percent) and education and communication (0.6 percent).
Over the year, the index for all items less food and energy increased 2.1 percent. Increases in the indexes for shelter (2.3 percent), recreation (10.0 percent), and medical care (5.6 percent) were major contributing factors.
The September 2017 Consumer Price Index for Chicago is scheduled to be released on Friday, October 13, 2017.
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.
