WHAT IS THE DIFFERENCE BETWEEN THE SURVEY POPULATION SIZE AND THE SURVEY SAMPLE SIZE?
The survey population size refers to the size of the population that is eligible to be included in the survey (e.g., for the CHS, all non-institutionalized New Yorkers age 18 and older who live in households with landline telephone service). The sample size refers to the size of the population that is actually contacted by phone and surveyed.
