Helping to meet the housing demand in the U.S.
Unit starts—also known as housing starts—refer to the number of new residential construction projects on which ground has already been broken. In the United States, the number of multifamily housing starts, which includes the development of apartments, has been increasing in the past ten years. In comparison, the number of single-family housing starts in the United States was much higher at over a million units in 2024.Â
