CONSUMER PRICE INDEX FOR ENERGY AND FOOD DETROIT-ANN ARBOR-FLINT, MI CMSA MARCH 2009

 

Energy costs in the Detroit-Ann Arbor-Flint Metropolitan area increased 0.7 percent in March, the U.S. Department of Labor’s Bureau of Labor Statistics reported today.  Overall energy costs decreased 22.5 percent over the past year, following an increase of 17.5 percent during the previous 12-month period.

 
The largest contributor to the monthly gain in energy costs was gasoline which rose 3.1 percent from February to March.  Costs for electricity, another component of the energy index, rose 1.1 percent.  Prices for utility (piped) gas service fell 2.7 percent over the month, partially offsetting these gains.  The 22.5 percent over-the-year decline in energy costs was mostly due to a 39.7 percent drop in prices at the gasoline pumps.  Costs for electricity rose 10.6 percent over the year, while costs for utility (piped) gas service fell 5.5 percent.

The cost of grocery food (food at home index) rose 0.2 percent during March.  Over the year, grocery food prices in the Detroit metro area were up 5.5 percent.  This follows increases of 0.4 and 3.1 percent during the previous two 12-month periods ending in March (2008 and 2007).

BRIEF EXPLANATION OF THE CPI

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 87 percent of the total population and (2) a CPI for Urban Wage Earners and Clerical Workers (CPI-W) which covers 32 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. Prices are collected in 87 urban areas across the country from about 50,000 housing units and approximately 23,000 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. Prices of food, fuels, and a few other items are obtained every month in all 87 locations. Prices of most other commodities and services are collected every month in the three largest geographic areas and every other month in other areas. Prices of most goods and services are obtained by personal visits of the Bureau's trained representatives.

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. Separate indexes are also published by size of city, by region of the country, for cross-classifications of regions and population-size classes, and for 27 local areas. Area indexes do not measure differences in the level of prices among cities; they only measure the average change in prices for each area since the base period.

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.
