More people are riding the subway during non-rush hours, new data released by the MTA shows.

Just 39 percent of straphangers said that they only ride the rails during the morning and evening rush — down from 49 percent in 2010, the MTA’s 2014 Customer Satisfaction Survey revealed.

“While traditional rush-hour ridership is holding steady, the highest subway ridership growth has come outside of 9-to-5 commuting,” said MTA spokesman Adam Lisberg.

“More and more customers are working non-traditional hours and riding the subway as their first choice to get around town outside of work.”

Subway crime has also gone down a lot, making people more comfortable to ride at night, an MTA source added.

Millenials, or people born in the eighties and nineties, are also using cars less and relying more on public transit.

Meanwhile, Metro-North riders’ satisfaction dropped from 93 to 73 percent, according to another MTA survey.

The drop comes after a year where the railroad had five accidents in New York City and Connecticut, including a derailment that killed four people in the Bronx.

Riders were frustrated with the railroad’s on-time performance, schedules, and communications with Metro-North– but liked the ‘Quiet Cars’ that were added onto its train lines in 2012.

“This year’s survey results are sobering but not surprising given the challenges Metro-North has faced during the last 18 months,” said its president Joseph Giulietti, who said the agency was being rebuilt.
