The Consumer Price Index for All Urban Consumers (CPI-U) for Miami increased 1.0 percent over the September-October pricing period, the U.S. Bureau of Labor Statistics reported today. Regional Commissioner Janet S. Rankin noted that the energy index advanced 6.3 percent over the two months. The all items less food and energy index rose 0.5 percent and the food index increased 0.8 percent over the pricing period. (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 rose 2.7 percent. The all items less food and energy index increased 2.3 percent and the energy index advanced 10.5 percent over the year. The food index was up 1.4 percent since October 2016. (See chart 1 and table 1.)

Food

The food index was up 0.8 percent during the September-October pricing period, led by a 1.3-percent increase in prices for food at home. Prices for food away from home edged up 0.2 percent over the two months.

Since October 2016, the food index rose 1.4 percent, reflecting price increases for food away from home (2.5 percent) and food at home (0.6 percent).

The energy index was up 6.3 percent during the two month pricing period—largely contributed to a 12.7-percent increase in motor fuel prices. Over the two months, prices for utility (piped) gas service were unchanged, while prices for electricity edged down 0.2 percent.

Over the year, the energy index advanced 10.5 percent, led by price increases for motor fuel and electricity, up 11.3 and 10.0 percent, respectively. Since October 2016, prices for utility (piped) gas service edged up 0.3 percent.

All items less food and energy

Since October 2016, the index for all items less food and energy increased 2.3 percent. Several indexes recorded increases, most notably shelter (4.6 percent) and medical care (8.8 percent). In contrast, the education and communication index declined 4.9 percent over the year.

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/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 Miami-Fort Lauderdale, Fla. consolidated area covered in this release is comprised of Broward and Miami-Dade Counties in Florida.
