How does BEA measure household production?
We use data from surveys that ask people how they spend their time. The United States is the only country that collects these statistics every year; the U.S. Bureau of Labor Statistics has been conducting its American Time Use Survey since 2003. To track long-term trends, BEA combines that survey's data with less comprehensive studies that have been conducted occasionally since 1965. BEA uses the wages of general-purpose domestic workers to estimate the value of this unpaid work that people do at home.
