The population comprises all persons represented by the sample of a survey. In the AGF system, the population depends on the selected market standard. In the TV market standard, it consists of persons aged 3 and over in private households with a German-speaking main income earner and at least one TV set in use. In the moving image market standard, people in private households who do not have a TV set but have at least one streaming-capable device in the household, so-called non-TV households, are added.
