Consumer Price Index, Chicago-Naperville-Elgin — November 2020

Area prices were down 0.4 percent over the past month, up 0.8 percent from a year ago

Prices in the Chicago-Naperville-Elgin area, as measured by the Consumer Price Index for All Urban Consumers (CPI-U), decreased 0.4 percent in November, the U.S. Bureau of Labor Statistics reported today.  Regional Commissioner Jason Palmer noted that the food index decreased 0.5 percent and the energy index fell 1.2 percent in November. The all items less food and energy index declined 0.3 percent in November. Among the indexes within the all items less food and energy category, prices were lower for apparel and new and used motor vehicles. (Data in this report are not seasonally adjusted. Accordingly, month-to-month changes may reflect seasonal influences.)

Over the last 12 months, the CPI-U increased 0.8 percent. (See chart 1 and table A.) Food prices rose 4.9 percent. Energy prices fell 8.3 percent, largely the result of a decrease in the price of gasoline. The index for all items less food and energy increased 0.8 percent over the year. (See table 1.)

Food

Food prices decreased 0.5 percent for the month of November.  Prices for food at home (groceries) fell 0.7 percent, and prices for food away from home (restaurant, cafeteria, and vending purchases) declined 0.2 percent for the same period. Within the food at home group, indexes were lower in November for nonfrozen noncarbonated juices and drinks, other fresh fruits, other fresh vegetables, and fresh fish and seafood. In contrast, the indexes for candy and chewing gum and eggs were higher.

Over the year, food prices rose 4.9 percent. Prices for food at home rose 4.8 percent since a year ago, and prices for food away from home rose 5.0 percent.

Energy

The energy index declined 1.2 percent over the month. The decrease was mainly due to lower prices for gasoline (-3.4 percent). Prices for utility (piped) gas service advanced 1.8 percent, and prices for electricity were unchanged for the same period.

Energy prices decreased 8.3 percent over the year, largely due to lower prices for gasoline (-18.7 percent). Prices paid for utility (piped) gas service rose 5.8 percent, and prices for electricity advanced 0.4 percent during the past year.

All items less food and energy

The index for all items less food and energy declined 0.3 percent in November. Lower prices for apparel (-3.2 percent) and new and used motor vehicles (-1.3 percent) were partially offset by higher prices for shelter (0.1 percent) and household furnishings and operations (0.2 percent).

Over the year, the index for all items less food and energy increased 0.8 percent. Components contributing to the increase included shelter (2.3 percent), medical care (1.7 percent), and used cars and trucks (11.4 percent). Partly offsetting the increases were price decreases in apparel (-6.7 percent) and motor vehicle insurance (-8.7 percent).

Coronavirus (COVID-19) Pandemic Impact on November 2020 Consumer Price Index Data

Data collection by personal visit for the Consumer Price Index (CPI) program has been suspended since March 16, 2020. When possible, data normally collected by personal visit were collected either online or by phone. Additionally, data collection in November was affected by the temporary closing or limited operations of certain types of establishments. These factors resulted in an increase in the number of prices considered temporarily unavailable and imputed.

While the CPI program attempted to collect as much data as possible, many indexes are based on smaller amounts of collected prices than usual, and a small number of indexes that are normally published were not published this month. Additional information is available at www.bls.gov/covid19/effects-of-covid-19-pandemic-on-consumer-price-index.htm.   


Technical Note

The Consumer Price Index (CPI) is a measures 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 U.S. population and (2) a CPI for Urban Wage Earners and Clerical Workers (CPI-W) which covers approximately 29 percent of the total U.S. 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 6,000 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; for most of the CPI-U the reference base is 1982-84 equals 100. An increase of 7 percent from the reference base, for example, is shown as 107.000.  Alternatively, that relationship can also be expressed as the price of a base period market basket of goods and services rising from $100 to $107. For further details see the CPI home page on the Internet at www.bls.gov/cpi and the CPI section of the BLS Handbook of Methods available on the internet at www.bls.gov/opub/hom/cpi/.

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-Naperville-Elgin, IL-IN-WI, Core Based Statistical Area covered in this release is comprised of Cook, DeKalb, DuPage, Grundy, Kane, Kendall, Lake, McHenry, and Will Counties in Illinois; Jasper, Lake, Newton, and Porter Counties in Indiana; and Kenosha County in Wisconsin.

Information in this release will be made available to sensory impaired individuals upon request. Voice phone: (202) 691-5200; Federal Relay Service: (800) 877-8339.
