Consumer Price Index, San Francisco area – December 2013
Area prices were down 0.4 percent over the past two months, up 2.6 percent from a year ago
Prices in the greater San Francisco area, as measured by the Consumer Price Index for All Urban Consumers (CPI-U), decreased 0.4 percent for the two months ending December 2013, the U.S. Bureau of Labor Statistics reported today. (See table A.) Regional Commissioner Richard J. Holden noted that the December decrease was influenced by lower prices for gasoline and apparel. (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 increased 2.6 percent. (See chart 1.) Energy prices advanced 2.4 percent, largely the result of an increase in the price of electricity. The index for all items less food and energy rose 2.5 percent since December 2012.
Food prices edged up 0.1 percent from October to December. (See table 1.) Prices for food away from home increased 0.3 percent, but prices for food at home edged down 0.1 percent for the same period.
Over the year, food prices rose 2.9 percent. Prices for food away from home advanced 4.3 percent since a year ago, and prices for food at from home increased 1.7 percent.
EnergyThe energy index decreased 5.0 percent for the two months ending in December 2013. The decrease was mainly due to lower prices for gasoline (-4.7 percent). Prices for natural gas service declined 8.8 percent, and prices for electricity decreased 5.2 percent since October.
Energy prices advanced 2.4 percent over the year, largely due to higher prices for electricity (5.9 percent). Prices paid for natural gas service advanced 1.1 percent, and prices for gasoline rose 0.9 percent during the past year.
All items less food and energy
The index for all items less food and energy inched down 0.1 percent in the latest two-month period. Lower prices for apparel (-5.3 percent) and recreation (-1.2 percent) were partially offset by higher prices for other goods and services (3.4 percent) and medical care (1.2 percent).
Over the year, the index for all items less food and energy rose 2.5 percent. Components contributing to the increase included medical care (5.7 percent), other goods and services (4.1 percent), and shelter (4.0 percent). Partly offsetting the increases were price declines in recreation (-2.7 percent) and apparel (-2.1 percent).
In December, the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) was 242.602, down 0.5 percent from October. The CPI-W increased 2.6 percent over the year.
The February 2014 Consumer Price Index for the San Francisco-Oakland-San Jose area is scheduled to be released March 18, 2014, at 10:00 a.m. (PST).
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 88 percent of the total population and (2) a CPI for Urban Wage Earners and Clerical Workers (CPI-W) which covers 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 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/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.
