The Consumer Price Index for All Urban Consumers (CPI-U) for Philadelphia-Wilmington-Atlantic City was unchanged from February to April, the U.S. Bureau of Labor Statistics reported today. Regional Commissioner Sheila Watkins noted that lower prices for all items less food and energy (-0.3 percent) were offset by higher prices for energy (2.6 percent) and food (1.0 percent) since February. (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 1.3 percent. (See chart 1 and table A.) The over-the-year rise was led by increases in the energy index (8.1 percent) and the all items less food and energy index (0.7 percent). Prices for food also rose since April 2016, up 1.3 percent. (See table 1.)

Food

Following a 0.7-percent rise from December to February, the food index increased 1.0 percent over the last two months. Prices were higher for both food at home (1.3 percent) and food away from home (0.5 percent) since February. Within the food at home component, higher prices for various items including nonfrozen noncarbonated juices and drinks and uncooked beef steaks were moderated by lower prices for ice cream and related products and uncooked ground beef, among others.

Over the year, the food index increased 1.3 percent. Prices for food away from home rose 2.1 percent and those for food at home increased 0.8 percent.

Energy

The energy index, which includes prices for household and transportation fuels, advanced 2.6 percent since February. This was due largely to higher prices for gasoline, up 4.1 percent over the last two months. Prices for utility (piped) gas service also increased since February, up 5.6 percent, while those for electricity declined, down 0.3 percent.

Over the year, the energy index rose 8.1 percent, led by an 18.0-percent advance in gasoline prices. Prices were also higher for utility (piped) gas service (6.5 percent), while those for electricity declined 3.1 percent over the year.

All items less food and energy

The index for all items less food and energy edged down 0.3 percent from February to April, led by lower prices for education and communication (-3.7 percent) and new vehicles. Higher prices for shelter (0.4 percent) moderated the decrease in the all items less food and energy index since February.

Since April 2016, the index for all items less food and energy increased 0.7 percent. This was largely due to higher prices for shelter (2.4 percent). Lower prices for education and communication (-3.1 percent), among others, moderated the 12-month increase in the all items less food and energy index.

Technical Note

The Consumer Price Index for Philadelphia-Wilmington-Atlantic City 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 89 percent of the total population and (2) a CPI for Urban Wage Earners and Clerical Workers (CPI-W) which covers approximately 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 4,000 housing units and approximately 26,000 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.
