Abstract
This study investigates associations between internal migration and health among middle-aged and older adults in China, including variations associated with type of migration (rural-to-urban, urban-to-rural, rural-to-rural, urban-to-urban). Data were drawn from China's Health and Retirement Longitudinal Study (2011, 2013, 2015). Lagged panel and fixed-effect regression models address associations between migration and health outcomes (self-rated health, depression) while controlling for pre-migration and post-migration selection effects. The results reveal the positive implications of rural-to-urban migration for the self-rated health of middle-aged but not older adults. They also point to the positive effects of migration within and to rural areas for the self-rated and mental health of older adults. Overall, although migration may be beneficial to the health of internal migrants in China, complexities associated with age, type of migration, and the health outcome involved need to be taken into account.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
