The State of the Nation's Housing 2018. Harvard Joint Center for Housing Studies, June 28, 2018, Paper, "As we mark the 30th anniversary of the State of the Nation’s Housing series, this year’s report presents an opportunity to reflect on how housing market conditions in the United States have evolved over the decades. In addition to our usual look at current trends, the analysis examines how some of today’s conditions echo the past and are a yardstick for the progress we as a nation have and have not made in fulfilling the promise of a decent, affordable home for all."
