What the Evidence Shows
The claim that 10% of housing in the U.S. Is artificially vacant requires unpacking. Data from multiple authoritative sources, including the U.S. Census Bureau and housing research organizations, indicate that the overall vacancy rate for housing units hovers around 10% to 10. 5% in recent years.usafacts.orgusafacts.orgHow many vacant homes are there in the US?

However, this vacancy rate encompasses all vacant units regardless of reason, including homes for sale, homes for rent, seasonal or vacation homes, homes under repair, and those genuinely unoccupied for other reasons. The term 'artificially vacant' implies intentional withholding from the market or purposeful vacancy to manipulate supply or prices, which is a narrower subset of total vacancies and is not directly quantified in these statistics.
For example, about one-third of vacant homes are vacation properties,census.govcensus.govIn 2020, 9.7% of Housing Was Vacant, Down From 11.4% in 2010 which may be intentionally left unoccupied seasonally but are not necessarily 'artificially' vacant in an economic manipulation sense. Additionally, some vacancies reflect normal market dynamics such as turnover periods between tenants or sales.
Therefore, while the overall vacancy rate is close to 10%, labeling all these as 'artificially vacant' overstates the case without further specification or evidence. The claim is mostly accurate regarding the percentage but misleading in implying all vacancies are artificial.
