New York City is notoriously crowded, and it's only getting more so. The city estimates it will have 1 million more people by the year 2030, many of them single. Where to place all these newcomers is a major challenge.
Mayor Mike Bloomberg has announced plans to put up an experimental building of micro-apartments that could be replicated throughout the city. And the Museum of the City of New York is looking at ways to make better use of the city's housing stock.
