Consumer Price Index, Portland – First Half 2015

Area prices up 0.1 percent over the past six months, up 1.3 percent from a year ago

Prices in the greater Portland area, as measured by the Consumer Price Index for All Urban Consumers (CPI-U), edged up 0.1 percent in the first half of 2015, the U.S. Bureau of Labor Statistics reported today. (See table A.) Regional Commissioner Richard J. Holden noted that this latest six-month increase was influenced by higher prices for shelter and medical care, but partially offset by lower prices for gasoline. (Data in this report are not seasonally adjusted. Accordingly, six-month-to-six-month changes may reflect seasonal influences.)

Over the past 12 months, the CPI-U rose 1.3 percent.  (See chart 1 and table A.) Energy prices fell 14.4 percent, mainly due to an increase in the price of gasoline. The index for all items less food and energy increased 2.6 percent over the year. (See table 1.)

Food

Food prices advanced 0.7 percent in the first half of 2015. (See table 1.) Prices for food away from home rose 1.5 percent for the past six months. Prices for food at home increased 0.5 percent for the same period. 

For the year ending in the first half of 2015, food prices rose 3.6 percent. Prices for food away from home advanced 4.4 percent during the past 12 months, and prices for food at home increased 3.3 percent.

Energy

Energy prices fell 12.6 percent since the second half of 2014. A drop in gasoline prices (-22.5 percent) offset higher prices for natural gas service and electricity (0.8 percent each).

Energy prices dropped 14.4 percent over the year, largely due to a decrease on gasoline prices (-25.0 percent). Prices for electricity moved up 0.7 percent, and prices for natural gas service increased 1.7 percent during the same period.

All items less food and energy

The index for all items less food and energy increased 1.2 percent from the second half of 2014 to the first half of 2015. Among the index components, price increases were recorded for medical care (3.1 percent), shelter (2.3 percent), and apparel (1.0 percent). In contrast, prices declined for education and communication (-1.4 percent), household furnishings and operations (-0.4 percent), and other goods and services (-0.3 percent).

Over the year, the index for all items less food and energy advanced 2.6 percent. Prices increased for shelter (5.1 percent), medical care (5.1 percent), and apparel (2.0 percent). Partially offsetting the increases were lower prices for alcoholic beverages (-1.6 percent) and education and communication (-0.7 percent).

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 www.bls.gov/opub/hom/homch17_a.htm.

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 Portland-Salem, OR, WA metropolitan area covered in this release consists of Clackamas, Columbia, Marion, Multnomah, Polk, Washington, and Yamhill Counties in the State of Oregon and Clark County in the State of Washington.
