The Consumer Price Index for All Urban Consumers (CPI-U) in the Northeast edged up 0.2 percent in September, the U.S. Bureau of Labor Statistics reported today. Sheila Watkins, the Bureau’s regional commissioner, noted that the all items less energy index and the energy index increased over the month, up 0.1 and 1.3 percent, respectively. Food prices also rose since August, inching up 0.1 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 Northeast all items CPI-U increased 1.3 percent, due to a 1.8-percent advance in the all items less food and energy index. (See chart 1 and table A.) The energy index declined 2.6 percent, while the food index was unchanged. (See table 1.)

Food

The food index inched up 0.1 percent over the month. Prices for food away from home edged up 0.3 percent, while prices for food at home were unchanged.  

From September 2015 to September 2016, the food index was unchanged as a 1.8-percent decrease in prices for food at home was offset by a 2.6-percent increase in those for food away from home.

Energy

The energy index, which includes prices for household and transportation fuels, rose 1.3 percent since August, due largely to a 1.9-percent increase in gasoline prices. Prices also increased for electricity and utility (piped) gas service, up 0.8 and 0.7 percent, respectively.

The energy index declined 2.6 percent since September 2015, led by a 5.9-percent decrease in gasoline prices. Prices for utility (piped) gas service and electricity advanced over the year, up 3.6 and 0.3 percent, respectively.

All items less food and energy

The index for all items less food and energy inched up 0.1 percent in September, led by a seasonal increase in apparel prices (3.9 percent). Prices for education and communication also increased, up 0.3 percent over the month. These and other increases were moderated by a 0.8-percent decline in prices for new and used motor vehicles.

Over the year, the index for all items less food and energy increased 1.8 percent, led by higher prices for shelter (2.6 percent). Prices were also higher over the year for medical care (4.2 percent), among others.

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 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.

The Northeast region is comprised of Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, and Vermont.
