Chinatown is the 2nd most densely populated neighborhood in the U.S., Manhattan being the most densely populated, but Chinatown doesn't have high-rise buildings like Manhattan does. A key contributor to Chinatown's density is that a majority of its population lives in SRO's. Occupants of an SRO rent a single room, usually less than 100 sq ft in size, and share bathrooms and kitchens, usually 1 per floor... now that's compact living! Consequently, outdoor public spaces are the "living room" of the neighborhood. There are a couple large public squares and parks that are well used, but in addition to those spaces, the alleyways have become essential community spaces.

This map is in the middle of Waverly Alley. There are 41 alleys, and recently there has been an effort to enhance the usability of those alleys through lighting, seating, plantings, re-paving, etc. It's a fascinating, San Francisco original experience, complete with a stop at the Golden Gate Fortune Cookie Factory.
