(N.Y. TIMES) The number of New Yorkers classified as poor in 2010 increased by nearly 100,000 from the year before, raising the poverty rate by 1.3 percentage points to 21 percent — the highest level and the largest year-to-year increase since the city adopted a more detailed definition of poverty in 2005.

The recession and the sluggish recovery have taken a particularly harsh toll on children, with more than one in four under 18 living in poverty, according to an analysis by the city’s Center for Economic Opportunity that will be released on Tuesday.

Families with children were also vulnerable. They had a poverty rate of 23 percent, and a significant number of households were struggling to remain above the poverty line. Even families with two full-time earners were more likely to be considered poor in 2010; their ranks swelled by 1.3 percentage points to 5 percent compared with 2009.
