Each month the Census Bureau carries out the Current Population Survey (CPS) (which has been carried out every month since 1940). A total of households are contacted every month.

The answer is 60,000 households are contacted.

Explanation:

The Current Population Survey is conducted by both the U.S. Census Bureau and the U.S. Bureau of Labor Statistics. It is the source that the United States government uses to keep track of labor statistics and the employment situation from week-to-week and month-to-month in the United States. It thus gives insight into one of the most important measures of economic health for the population at large and general trends can be monitored and measured using the results.  The survey also tracks other indicators like health insurance coverage.
