Unemployment is down slightly across the city, but a new study released Monday finds the jobless rate varies drastically from neighborhood to neighborhood.

According to new estimates by the Fiscal Policy Institute, unemployment in the third quarter of the year on Manhattan's Upper East Side and Upper West Side was 5.1 percent.

In the South and Central Bronx, it was 15.7 percent, and in Brooklyn's East New York, it was 19.2 percent.

The study also finds a vast unemployment gap among races, with 15.7 percent of blacks out of work, compared to 11.8 percent of Hispanics, 7.3 percent for non-Hispanics, and 6.1 percent for Asians and other New Yorkers.

Unemployment was also higher for men than for women.

The highest gender race/ethnicity unemployment rate in the city was recorded in West Brooklyn, encompassing the area from Brooklyn Heights to Red Hook and Park Slope, where black male unemployment is at 46 percent.

Fiscal Policy Institute Chief Economist James Parrott says the study shatters some previous assumptions about the New York City economy.

“What this indicates is the recession has hit New York City, not just at Wall Street, even though this recession is characterized by the September 2008 meltdown,” Parrott said. “It’s actually affected many parts, in construction, wholesale, retail, in many parts of the city far from Wall Street, both geographically and otherwise, we see hard and persistent unemployment.”

Parrott said he believes the recent reported decrease in unemployment might have been a reflection of people who've gone off the benefit grid and stopped looking for jobs all together.
