Nicole Gelinas joins Seth Barron to discuss her research on New York subway ridership, the future of the city's subways, and the decriminalization of fare-jumping, a reversal of a critical policing strategy that helped fight crime.

Subway ridership in New York has nearly doubled since 1977, but it's not tourists packing the trains: it's city residents. And New York's poorest neighborhoods have seen the biggest growth in annual ridership over the last 30 years.

The subway's future looks uncertain, though. Decades of storm damage, insufficient maintenance, and inadequate system upgrades have led to mounting delays and declining reliability. If city leadership doesn't address the crisis, New York's poorest residents will be most affected.
