The Consumer Price Index for All Urban Consumers (CPI-U) for Philadelphia-Camden-Wilmington decreased 0.4 percent from August to October, the U.S. Bureau of Labor Statistics reported today. Regional Commissioner Sheila Watkins noted that the recent two-month decline reflected a 0.2-percent decreased in the all items less food and energy index and a 2.3-percent decline in the energy index, while the food index rose since August, up 0.2 percent. (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 CPI-U increased 1.9 percent. (See chart 1 and table A.) The over-the-year rise was led by an increase in the all items less food and energy index (2.5 percent). The food index also advanced since October 2018, up 2.0 percent, while the energy index declined 3.6 percent. (See table 1.)

Food

The food index edged up 0.2 percent over the last two months. Prices for food away from home increased since August, up 0.8 percent, while those for food at home declined 0.2 percent. Within the food at home component, prices were lower for chicken and bacon, breakfast sausage, and related products; while prices were higher for breakfast cereal and fresh fish and seafood.

Over the year, the food index increased 2.0 percent. Prices for food away from home rose 2.6 percent, and those for food at home were up 1.5 percent.

Energy

The energy index, which includes prices for household and transportation fuels, decreased 2.3 percent since August. The two-month decline was led by a 4.0-percent decrease in gasoline prices. Prices were also lower for electricity and utility (piped) gas service, down 1.9 and 1.3 percent, respectively.

Over the year, the energy index declined 3.6 percent, due to lower gasoline prices, down 9.8 percent. Prices were higher for utility (piped) gas service (6.9 percent) and electricity (2.1 percent) since October 2018.

Technical Note

The Consumer Price Index for Philadelphia-Camden-Wilmington is published bi-monthly. 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 93 percent of the total population and (2) a CPI for Urban Wage Earners and Clerical Workers (CPI-W) which covers approximately 29 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 75 urban areas across the country from about 5,000 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 (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 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.
