In the USA, annual production of new housing has declined dramatically since 2006. 
The decline began more than two years before the near collapse of the financial system in September 2008. By mid 2010, per capita production of new housing stood at levels not seen since the depths of the Great Depression in 1933 and in 1944 during World War II.
More recent data shows that per capita sales of new housing have declined further since 2008.
