Abstract
Recent studies of migration and the left-behind have found that elders with migrant children actually experience better health outcomes than those with no migrant children, yet these studies raise many concerns about self-selection. Using three rounds of panel survey data from the Indonesian Family Life Survey, we employ the counterfactual framework developed by Rosenbaum and Rubin to examine the relationship between having a migrant child and the health of elders aged 50 and older, as measured by activities of daily living (ADL), self-rated health (SRH), and mortality. As in earlier studies, we find a positive association between old-age health and children’s migration, an effect that is partly explained by an individual’s propensity to have migrant children. Positive impacts of migration are much greater among elders with a high propensity to have migrant children than among those with low propensity. We note that migration is one of the single greatest sources of health disparity among the elders in our study population, and point to the need for research and policy aimed at broadening the benefits of migration to better improve health systems rather than individual health.

Notes
Our results for rural respondents hold for urban areas, although models that combine both rural and urban populations tend to be driven by the rural results.
The four-category general health question yielded little variation between the poor versus nonpoor dichotomy. In the study group, 95% of respondents were either “somewhat healthy” or “somewhat unhealthy,” 4% were unhealthy, and 1% were healthy.
The term district refers to the kabupaten, or regency: the unit of government below province.
Deciles cover the following ranges in U.S. dollars: 0–225; 227–588; 589–1,000; 1,009–1,506; 1,507–2,197; 2,203–3,069; 3,072–4,466; 4,470–6,714; 6,769–12,608; 12,667–42,000.
For child characteristics, we use data from IFLS-2 (1997) to ensure comparability to our independent migration variable, which is calculated from IFLS-2. For household asset variables, we use data from IFLS-1 (1993) to capture socioeconomic predisposition over a longer time span.
Separate counts for male and female children were not included because they did not improve model fit. This conforms with previous research, suggesting that male and female migration patterns are comparable in this population (Frankenberg and Kuhn 2004).
While statistical power is limited in our low propensity block, with only 56 treatment cases of 560 total, the effects are well below the level of statistical significance.
These are predicted probabilities derived from separate models; thus, the results are not directly comparable.
