The number of New York City residents receiving food stamps more than doubled over the past decade under Mayor Bloomberg, according to data released yesterday.

Now, 1.8 million receive food stamps, a jump from 800,000 in 2002, the Independent Budget Office data show.

IBO spokesman Doug Turetsky cited more aggressive outreach to enroll eligible recipients by the Bloomberg administration, in comparison to his predecessor, Rudy Giuliani.

The cost of the federally funded food-stamp program in the city skyrocketed to $3.4 billion from $1.28 billion over the past decade.
