1.

The population of interest in the CPS is the civilian noninstitutionalized population, which includes individuals who are 16 years and older, not in the military, and not living in institutions such as prisons or nursing homes.

2.

The sample used is about 60,000 households or approximately 110,000 individuals each month. The CPS methodology is unique that it uses a rotating panel design, where households are interviewed for a maximum of 8 months, and then replaced by a new household.

3.

I think it is quite convincing.
