The world’s population is growing at an unprecedented rate. In 2020, there were 331 million people recorded living in the United States, a 46% increase since 1980.1 With that, the COVID-19 pandemic has altered many aspects of our country, including the housing industry. To understand the landscape of real estate before the pandemic, we analyzed the historic housing availability in the U.S., specifically which counties have the most improved housing availability.

To understand which counties had the most improvement historically, we looked at available housing units from 2010 – 2019 data from the recorded 3,142 counties in the U.S. We then adjusted the housing difference based on the average size of households in the United States in 2010 and 2019, at 2.59 and 2.52 people per household, respectively.

Learn which counties had the most improved housing plus affordable housing resources to help buy your new home.
