摘要

The NAHB Research Centers Builder Practices Reports provide a comprehensive look into new home characteristics and the products and materials purchased by home builders nationwide. The reports are based on data obtained through the Annual Builder Practices Survey, a nationally disseminated paper survey of home builders. The resulting data are tabulated using a robust methodology that includes balancing on geographic and demographic variables to provide an accurate picture of the characteristics of homes built each calendar year. The Builder Practices Reports present data on materials purchased for single-family detached homes and Multifamily dwelling units. These data are shown as coefficients, which are perhouse averages, and product usage, which is the total volume of homes with certain characteristics built in each geographic area.
