A huge portion of northern, eastern and southern queens, eastern brooklyn, and staten island is more than a 10 minute walk from the subway. I live in Queens and am a 40 minute bus ride from the nearest subway station. Swaths of brooklyn are the same.

Here's a map showing the tiny portion of Queens in walking distance of subways. https://cwhong.carto.com/viz/6dfca01c-47e5-11e6-9fd3-0ee66e2.... And yes, it's almost all residential zoned, filled brick to brick with houses and apartments.

Based on this density map (https://www.google.com/search?q=pppulation+densoty+map+nyc&o...) I'd peg it at 35% of the city's pop.

35% is higher than I would have guessed but not out of bounds of my expectations. Also like a typical New Yorker I'm completely ignoring Staten Island. In terms of commuting patterns and geography it would make more sense to unify PATH with the subway, make Hoboken a borough, and cede SI to NJ in exchange.
