The Association Between Oldest Son Status and Co-Residence with Parents Across Periods and Cohorts in South Korea
Bibliographic record
Abstract
To explore patriarchal kinship structure centered on the oldest son across cohorts and time periods, this study compares intergenerational co-residence in the Korean War after Liberation Day (KWALD) cohort and the Korean Baby Boomer (KBB) cohort in 2006 and 2014. Participants are 1,763 KLoSA respondents born between 1945 and 1962 who participated in the Korean Longitudinal Study of Aging survey in both 2006 and 2014 and had living parents at both waves of the survey. Using multiple group analyses the results show that the pattern of the patriarchal kinship structure based on the oldest son status tends to remain in both the KWALD and KBB cohorts. However, in the KBB cohort the family structure based on the oldest son status was weakened in 2014 compared to 2006. These results have implications for the social norms that influence family structure in later life by time period and cohort.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
