On a monthly basis we track the numbers of housing units authorized by permits, started, sold or completed. We measure the dollar value of all construction put in place each month. We track residential construction in 30 metropolitan areas across the country each quarter, and the sales of new one-family houses in those areas each year. We tabulate and publish the dollar value of residential improvement and repair work each quarter. Our Census of Construction Industries, taken every five years, provides the most comprehensive overview of the construction industry available.
