Prices in the Denver-Aurora-Lakewood area, as measured by the Consumer Price Index for All Urban Consumers (CPI-U), increased 0.4 percent for the two months ending in September 2023, the U.S. Bureau of Labor Statistics reported today. Assistant Commissioner for Regional Operations Michael Hirniak noted that the all items less food and energy index rose by 0.3 percent in August and September, largely due to an increase in the owners’ equivalent rent of residences index. The energy index was up 1.6 percent, while the food index increased 0.6 percent over the past two months. (Data in this report are not seasonally adjusted. Accordingly, bi-monthly changes may reflect seasonal influences.)

Over the last 12 months, the CPI-U advanced 5.4 percent. The index for all items less food and energy also increased 5.4 percent over the year. Food prices rose 3.9 percent, while energy prices advanced 8.6 percent. (See chart 1 and table 1.)

Food prices rose 0.6 percent for the two months ending in September. Prices for food at home (grocery store prices) increased 0.7 percent, and prices for food away from home (restaurant, cafeteria, and vending purchases) advanced 0.3 percent for the two-month period. Within the food at home category, an increase in the index for meats, poultry, fish, and eggs (+6.3 percent) was partially offset by declines in the indexes for cereals and bakery products (-2.5 percent) and dairy and related products (-2.1 percent).

Over the year, food prices advanced 3.9 percent, mainly driven by prices for food away from home, which increased 7.8 percent. Prices for food at home advanced 1.4 percent, with the indexes for fruits and vegetables (+4.0 percent) and meats, poultry, fish, and eggs (+3.0 percent) contributing most to the rise in the index for the same period.

The energy index increased 1.6 percent for the two months ending in September. The increase was mainly due to higher prices for gasoline (+2.2 percent). Electricity prices were unchanged for the two-month period.

From September 2022 to September 2023, energy prices advanced 8.6 percent. Prices increased for gasoline (+7.2 percent), while prices decreased for electricity (-3.0 percent) over the past year.

The index for all items less food and energy rose 0.3 percent in the latest two-month period. Higher prices for owners’ equivalent rent of residences (+0.7 percent), tuition, other school fees, and childcare (+5.9 percent), and apparel (+7.4 percent) were partially offset by lower prices for lodging away from home, public transportation, and used cars and trucks (-6.8 percent).

Over the year, the index for all items less food and energy advanced 5.4 percent. Components contributing to the rise included owners’ equivalent rent of residences (+8.7 percent), rent of primary residence (+7.9 percent), and education and communication (+4.6 percent). Prices for used cars and trucks declined 8.6 percent over the same period, partially offsetting these increases.

The November 2023 Consumer Price Index for the Denver-Aurora-Lakewood area is scheduled to be released on Tuesday, December 12, 2023.

The Consumer Price Index (CPI) measures 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 Denver-Aurora-Lakewood, CO, Core Based Statistical Area is comprised of Adams, Arapahoe, Broomfield, Clear Creek, Denver, Douglas, Elbert, Gilpin, Jefferson, and Park counties in Colorado.
