The Consumer Price Index for All Urban Consumers (CPI-U) for the South was up 0.4 percent in April, the U.S. Bureau of Labor Statistics reported today. The energy index advanced 3.2 percent over the month and the all items less food and energy index edged up 0.3 percent. The food index was unchanged in April. (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 all items CPI-U rose 0.9 percent. The all items less food and energy index increased 2.1 percent over the year reflecting price increases for shelter, medical care, and education and communication. (See chart 1.)

Food

The food index was unchanged in April. Prices for food away from home inched up 0.1 percent over the month, while those for food at home were unchanged.

Since April 2015, the food index rose 0.7 percent, reflecting higher prices for food away from home (2.1 percent). The food at home index edged down 0.3 percent over the year.

Energy

The energy index advanced 3.2 percent in April, led by an 8.1-percent rise in motor fuel prices. The electricity and utility (piped) gas service indexes each declined over the month, down 0.6 and 0.8 percent, respectively.

Over the year, energy prices declined 9.7 percent, reflecting a 15.0-percent drop in motor fuel prices. Prices for electricity (-3.8 percent) and utility (piped) gas service (-6.3 percent) also declined over the year.

All items less food and energy

The all items less food and energy index edged up 0.3 percent in April led by an increase in the shelter index (0.3 percent).

The Consumer Price Index for May 2016 is scheduled to be released on Thursday, June 16, 2016.

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 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 https://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.

The South region is comprised of Alabama, Arkansas, Delaware, District of Columbia, Florida, Georgia, Kentucky, Louisiana, Maryland, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, Virginia, and West Virginia.
