Each month interviewers visit about 59,000 of the 98 million households in the U.S. and question the occupants over 14 years of age about their employment status.

What is the population of interest to the Census? What is the size of the population? What is n, the size of the sample? b. What variable is being measured? Is it quantitative or qualitative? e. Is the problem of interest to the Census Bureau descriptive or inferential?
