Estimating intergenerational health transmission in Taiwan with administrative health records

Abstract

We use population-wide administrative health records from Taiwan to estimate intergenerational persistence in health, providing the first estimates for a middle-income country. We measure latent health by applying principal components analysis to a set of indicators for 13 broad ICD categories and quintiles of visits to a general practitioner. We find that the rank–rank slope in health between adult children and their parents is 0.22 which is broadly in line with results from other countries. Maternal transmission is stronger than paternal transmission and sons have higher persistence than daughters. Persistence is also higher at the upper tail of the parent health distribution. Persistence is lower when complete data on outpatient care is unavailable. Health transmission is almost entirely unrelated to household income levels in Taiwan. We also find that there are small geographic differences in absolute health mobility across townships and that these are modestly correlated with area-level income and doctor availability.
