Comparability — South Korea [top]

In 2004 and 2009, child and son/daughter-in-law were not able to be distinguished in nearly 250 cases. In case there are only two people (men and women) coded as the married child/in law of the reference person in the same household, and both stated that they are married, then we imputed them as partners. Just under 150 cases were matched up as couples. The partners of siblings of main reference person were not able to be identified, because married siblings and their partners were coded as ‘others’ in Korean data.

In 2009, under 700 people answered ‘married’, but no partner was recorded in the household. We coded them as CVISTAT=1, with PARTID= -8 (partner unidentifiable). This could be the case that these people do not live together, or the partner did not participate in the survey (e.g, not available or refused to participate), but we cannot distinguish which is the case.

In 1985, there is no household roster; therefore, PARTID along with PARNTID2, PARNTID1, and RELREFP are constructed based on the following logic.

• For single-person households, no partner or parents are present.
• For two-person couple households, no parents are present and PARTID is easily assigned.
• For households containing couples with children or couples and others AND only one diarist reports being married and another diarist is missing or two people report being married and no one else in the household reports being married, the couples are considered married.
• In cases where there are multiple eligible partners or an odd number of married individuals, we privilege age similarity in partnering couples.
