In September, Somerset County, MD, had the highest unemployment rate on the Delmarva Peninsula at 5.5 percent, the U.S. Bureau of Labor Statistics reported today. Sheila Watkins, the Bureau’s regional commissioner, noted that 9 of the 14 Delmarva Peninsula counties had jobless rates higher than the 4.1-percent U.S. average. Among the five counties with jobless rates below the national average, Queen Anne’s County, MD, had the lowest rate, at 3.1 percent. (See chart 1 and chart 2. All data in this release are not seasonally adjusted; accordingly, over-the-year analysis is used throughout.)

Eleven of the 14 counties on the Delmarva Peninsula had unemployment rate decreases from September 2016 to September 2017. (See table A.) Four Maryland counties—Caroline, Dorchester, Wicomico, and Worcester—had the largest over-the-year declines at -1.0 percentage point each, above the national decline (-0.7 point). Six counties had over-the-year unemployment rate declines that were smaller than the national decrease with the smallest in  Accomack County, VA (-0.3 percentage point). The three Delaware counties had over-the-year increases of 0.4 percentage point each.

Jobless rates in 12 Delmarva Peninsula counties in September 2017 were lower than in September 2015. The unemployment rates in New Castle, DE, and Sussex, DE, were unchanged since September 2015. Two-year jobless rate decreases in the nine Maryland counties exceeded the national decline of -0.8 percentage point, with the largest decline in Worcester, MD (-2.1 percentage points).

The Metropolitan Area Employment and Unemployment news release for October is scheduled to be released on Thursday, November 30, 2017, at 10:00 a.m. (EDT).

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 12^th 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.

Methods of Estimation. The LAUS program is a hierarchy of non-survey methodologies for indirectly estimating employment and unemployment in states and local areas. Statewide data are produced through a modeling technique that uses estimates of payroll jobs from the Current Employment Statistics survey and unemployment insurance claims counts from the state workforce agencies to mitigate volatility in the direct CPS tabulations of employment and unemployment, respectively. Data for counties are developed through a building-block approach and adjusted proportionally to state model-based totals. For multi-county areas, such as the metropolitan areas and metropolitan divisions delineated by the Office of Management and Budget, estimates are summed from the data for their component counties. Estimates for cities and towns are produced through a disaggregation technique. A detailed description of the LAUS estimation procedures is available in chapter 4 of the BLS Handbook of Methods at www.bls.gov/opub/hom/pdf/homch4.pdf.

Annual revisions. Labor force and unemployment data for prior years reflect adjustments made at the end of each year, usually implemented with January estimates. The adjusted estimates reflect updated population data from the U.S. Census Bureau, any revisions in the other data sources, and model reestimation. All substate estimates are reestimated and adjusted to add to the revised model-based estimates.

The Delmarva Peninsula, located on the east coast of the United States, comprises Delaware and portions of Maryland and Virginia. The Delmarva Peninsula includes Kent, New Castle, and Sussex Counties in Delaware; Caroline, Cecil, Dorchester, Kent, Queen Anne’s, Somerset, Talbot, Wicomico, and Worcester Counties in Maryland; and Accomack and Northampton Counties in Virginia.
