Consumer Price Index, West Region — January 2017

Area prices were up 0.5 percent over the past month, up 2.5 percent from a year ago

Prices in the West Region, as measured by the Consumer Price Index for All Urban Consumers (CPI-U), advanced 0.5 percent in January, the U.S. Bureau of Labor Statistics reported today. (See table A.) The January increase was influenced by higher prices for shelter and gasoline. (Data in this report are not seasonally adjusted. Accordingly, month-to-month changes may reflect seasonal influences.)

Over the last 12 months, the CPI-U advanced 2.5 percent.  (See chart 1 and table A.) Energy prices increased 4.3 percent, largely the result of an increase in the price of gasoline. The index for all items less food and energy rose 2.9 percent over the year. (See table 1.)

Food

Food prices increased 0.3 percent for the month of January. (See table 1.) Prices for food away from home increased 0.7 percent, while prices for food at home were virtually unchanged for the same period.

Over the year, food prices inched down 0.1 percent. Prices for food at home declined 2.2 percent since a year ago, but prices for food away from home rose 2.9 percent.

Energy

The energy index advanced 2.4 percent over the month. The increase was mainly due to higher prices for gasoline (5.1 percent). Prices for electricity decreased 0.4 percent, and prices for natural gas service decreased 1.1 percent for the same period.

Energy prices increased 4.3 percent over the year, largely due to higher prices for gasoline (6.0 percent). Prices paid for electricity rose 2.6 percent, and prices for natural gas service increased 1.3 percent during the past year.

All items less food and energy

The index for all items less food and energy advanced 0.4 percent in January. Higher prices for recreation (0.9 percent) and apparel (0.6 percent) were partially offset by lower prices for education and communication (-0.5 percent).

Over the year, the index for all items less food and energy rose 2.9 percent. Components contributing to the increase included shelter (5.3 percent) and medical care (3.3 percent). Partly offsetting the increases were price declines in used cars and trucks (-3.9 percent) and education and communication (-1.8 percent).

The February 2017 Consumer Price Index for the West Region is scheduled to be released on March 15, 2017.


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 West Region covered in this release is comprised of the following thirteen states: Alaska, Arizona, California, Colorado, Hawaii, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming.

Information in this release will be made available to sensory impaired individuals upon request. Voice phone: (202) 691-5200; Federal Relay Service: (800) 877-8339.
