In September, Chester County, Pa., recorded the lowest unemployment rate in the Philadelphia-Camden-Wilmington, Pa.-N.J.-Del.-Md. Metropolitan Statistical Area (MSA) at 5.9 percent, followed by Montgomery County, Pa., at 6.5 percent, the U.S. Bureau of Labor Statistics reported today. Sheila Watkins, the Bureau’s regional commissioner, noted that Philadelphia County, Pa., at 10.9 percent, registered the highest unemployment rate among the 11 counties that make up the metropolitan area. Three New Jersey counties—Camden, Salem, and Gloucester—also recorded jobless rates that exceeded the U.S. average of 8.8 percent. (See chart 1 and chart 2. The Technical Note at the end of this release contains metropolitan area definitions. All data in this release are not seasonally adjusted; accordingly, over-the-year analysis is used throughout.)

Ten counties in the Philadelphia metropolitan area had unemployment rates that were lower in September 2011 than a year earlier, led by a 0.8-percentage point decline in Cecil County, Md. The nine other over-the-year decreases in the area ranged from 0.2 percentage point to 0.6 percentage point. Nationally, the unemployment rate decreased 0.4 percentage point since last year. The only county with an over-the-year increase in its unemployment rate was Philadelphia, Pa, up 0.2 percentage point since September 2010. (See table A.)

Unemployment rates in nine Philadelphia-area counties were lower in September 2011 than in September 2009. All of these decreases were 0.5 percentage point or less, below the national average decline of 0.7 percentage point. Only Philadelphia, Pa., had a higher unemployment rate from September 2009 to September 2011, up 0.6 percentage point. The unemployment rate was unchanged in Delaware County, Pa., over the last two years.
The September 2011 unemployment rates for the three metropolitan divisions in the Philadelphia-Camden-Wilmington MSA were 8.2 percent in the Philadelphia, Pa., division, 8.3 percent in the Wilmington, Del.-Md.-N.J., division, and 9.3 percent in the Camden, N.J., division. Since September 2010, all three divisions posted small unemployment rate declines ranging from 0.1 to 0.4 percentage point.  

Technical Note

This release presents unemployment rate data for states and counties from the Local Area Unemployment Statistics (LAUS) program, a federal-state cooperative endeavor.

Definitions. The labor force and unemployment data are based on the same concepts and definitions as those used for the official national estimates obtained from the Current Population Survey (CPS), a sample survey of households that is conducted for the Bureau of Labor Statistics (BLS) by the U.S. Census Bureau. The LAUS program measures employment and unemployment on a place-of-residence basis. The universe for each is the civilian noninstitutional population 16 years of age and over. Employed persons are those who did any work at all for pay or profit in the reference week (the week including the 12th of the month) or worked 15 hours or more without pay in a family business or farm, plus those not working who had a job from which they were temporarily absent, whether or not paid, for such reasons as labor-management dispute, illness, or vacation. Unemployed persons are those who were not employed during the reference week (based on the definition above), had actively looked for a job sometime in the 4-week period ending with the reference week, and were currently available for work; persons on layoff expecting recall need not be looking for work to be counted as unemployed. The labor force is the sum of employed and unemployed persons. The unemployment rate is the number of unemployed as a percent of the labor force.

Method of estimation. Estimates for the substate areas in this release are prepared through indirect estimation procedures using a building-block approach. Employment estimates, which are based largely on "place of work" estimates from the Current Employment Statistics (CES) program, are adjusted to refer to place of residence as used in the CPS. Unemployment estimates are aggregates of persons previously employed in industries covered by state unemployment insurance (UI) laws and entrants to the labor force data from the CPS. The substate estimates of employment and unemployment, which geographically exhaust the entire state, are adjusted proportionally to ensure that they add to the independently estimated state or balance-of-state totals. A detailed description of the estimation procedures is available from BLS upon request.

Annual revisions. Labor force and unemployment data for prior years reflect adjustments made at the end of each year. The adjusted estimates reflect updated population data from the U.S. Census Bureau, any revisions in the other data sources, and model reestimation. In most years, historical data for the most recent five years (both seasonally adjusted and not seasonally adjusted) are revised near the beginning of each calendar year, prior to or coincident with the release of January estimates.
