The symptoms of housing crisis are everywhere in evidence today. Households are being squeezed by the cost of living. Homelessness is on the rise. Evictions and foreclosures are commonplace. Segregation and poverty, along with displacement and unaffordability, have become the hallmarks of today’s cities. Urban and suburban neighborhoods are being transformed by speculative development, shaped by decisions made in boardrooms half a world away. Small towns and older industrial cities are struggling to survive.

In America, the housing crisis is especially acute in New York City. The city has more homeless residents now than at any time since the Great Depression. More than half of all households cannot afford the rent. Displacement, gentrification, and eviction are rampant. Two pillars of New York’s distinctive housing system — public housing and rent regulation — are both under threat.

But housing problems are not unique to New York. Shelter poverty is a problem throughout the United States. According to the standard measures of affordability, there is no US state where a full-time minimum-wage worker can afford to rent or own a one-bedroom dwelling.
