Job losses from casinos closings are beginning to show historic impacts on the region’s unemployment rate, according to recently released data.

Atlantic County’s seasonally adjusted unemployment rate in September had the largest monthly increase in at least a quarter century, according to data provided by the Federal Reserve Bank of Philadelphia.

The figures are seasonally adjusted, which reduces fluctuations common in tourist areas.

Atlantic County’s unemployment rate was pegged at 11.4 percent, an increase of 1.3 percentage points from August.

This meant 5,400 more people were counted as unemployed in September than the month prior, with 4,900 of them in the leisure and hospitality industry.

Area economists had expected this for months.

The closings of Showboat Casino Hotel on Aug. 31, as well as the Revel Casino-Hotel and Trump Plaza Hotel and Casino in September, were not fully reflected when August’s unemployment rate was released a month ago.

Other South Jersey counties were not nearly as affected.

Cape May County’s seasonally adjusted unemployment rate in September was 9.9 percent, a nominal increase from the previous month.

And Cumberland County’s dropped slightly, from 9.8 percent to 9.6 percent.

Unemployment rates are only a gauge of joblessness, but do not reflect discouraged workers and those who gave up looking for work.
