The Fire Department of New York is making headway three years into a process that has changed recruitment and hiring.

Minorities now make up 17 percent of its uniformed ranks at the nation's largest fire department, compared to about 10 percent in 2012.

Still, it's far from representative of a city where over half of residents are members of minority groups. Minority firefighter leaders say the department needs to do more, and demographic shifts haven't always changed firehouse culture.

A current of antipathy spilled into the forefront recently, when a fire chief was docked 50 days' pay amid an investigation into leaks of damaging information about minority firefighters' performance.

But FDNY Commissioner Daniel Nigro (NIGH'-gro) says he is pushing for a more diverse department and won't tolerate anyone thwarting it.
