Reporting unit classification, round record


[ PRELIMINARY VARIABLE: Variable description may change once we confirm the universe and assess the comparability of this variable over time. ]

RUCLAS is a round-level variable that reports whether a RU is Standard, New, or a Student.
A Reporting Unit (RU) is a person or group of persons in the sampled DU (Dwelling Unit) who are related by blood, marriage, adoption, foster care, or other family association.

Standard RUs are the original RUs from the National Health Interview Survey. A New RU is created when members of the household leave the primary RU and are followed according to the rules of the survey. A Student RU is an unmarried college student (under 24 years of age) who is considered a usual member of the household, but was living away from home while going to school, and was treated as a Reporting Unit separate from his or her parents' RU for the purpose of data collection.
