In addition, local indexes are not adjusted for seasonal influences. 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. Local data are then combined to obtain a U.S. For further details see the CPI home page on the Internet at and the CPI section of the BLS Handbook of Methods available on the internet at 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. 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. An increase of 7 percent from the reference base, for example, is shown as 107.000. The index measures price changes from a designated reference date for most of the CPI-U the reference base is 1982-84 equals 100. All taxes directly associated with the purchase and use of items are included in the index.

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. 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. 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. population and (2) a CPI for Urban Wage Earners and Clerical Workers (CPI-W) which covers approximately 29 percent of the total U.S. 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. 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. Additional information is available at Technical Note 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. These factors resulted in an increase in the number of prices considered temporarily unavailable and imputed. Additionally, data collection inВ July 2021В was affected by the temporary closing or limited operations of certain types of establishments. When possible, data normally collected by personal visit were collected either online or by phone. Partly offsetting the increases were falling prices for motor vehicle insurance (-9.3 percent).Дata collection by personal visit for the Consumer Price Index (CPI) program has been suspended since March 16, 2020. Higher prices for new and used motor vehicles (23.5 percent), ownersвЂ™ equivalent rent of residences (3.4 percent) and rent of primary residence (3.1 percent) contributed most to the increase.

Over the year, the index for all items less food and energy rose 4.6 percent. These increases were partially offset by lower prices for apparel (-5.4 percent), household furnishings and operations (-1.1 percent), as well as recreation (-0.4 percent). The latest movement was primarily fueled by higher prices for used cars and trucks (11.0 percent), ownersвЂ™ equivalent rent of residences (0.9 percent) and rent of primary residence (1.3 percent). The index for all items less food and energy rose 0.7 percent in June and July, after rising 1.7 percent in April and May. Prices paid for natural gas service jumped 25.0 percent, while prices for electricity edged up 0.1 percent over the year. The latest increase was mainly due to higher prices for electricity (3.8 percent), but prices for gasoline (1.4 percent) and natural gas service (1.5 percent) also increased for the same period.ДЇrom July 2020 to July 2021, energy prices jumped 22.3 percent, almost entirely due to higher prices for gasoline (45.1 percent). The energy index rose 2.3 percent for the two months ending in July, after rising 4.5 percent in the two months ending in May. The rise reflected an increase in prices for both food at home and food away from home, which rose 3.7 percent and 3.9 percent, respectively. Within the two components of the index, prices for food at home advanced 0.8 percent, while prices for food away from home also advanced 0.8 percent for the same period.Дuring the 12 months ending in July 2021, the index for food rose 3.8 percent.
