Staten Islanders Keep it in the Borough
Freemark's data digging reveals that the majority of Staten Island commuters don't leave the island for their jobs, commuting internally only:
"Those that don't generally work in downtown and midtown Manhattan and on the western edge of Brooklyn. A few work in Bayonne, Hoboken, and Queens' Long Island City."
"The light rail line is destined to serve an increasingly important role as a north-south connector on the west side of the Hudson River. But just how useful would an expansion into Staten Island be?"
