Substantial inequalities in healthcare utilisation are reported in Indonesia. To develop appropriate health policies and interventions, we need to better understand geographical patterns in inequalities and any contributing factors. This study investigates geographical inequalities in healthcare utilisation across 497 districts in Indonesia and whether compositional factors - wealth, education, health insurance - contribute to such inequalities. Using data from a nationally representative Basic Health Research survey, from 2013 (N = 694,625), we applied multilevel logistic regressions, adjusted for need, to estimate associations of compositional factors with outpatient and inpatient care utilisation and to assess variability at province and district levels. We observed large variation of healthcare utilisation at district level and smaller variations at province level. Cities had higher utilisation rates than rural districts. Compositional factors contributed only modestly to geographical inequalities in healthcare utilisation. The effect of compositional factors on individual healthcare utilisation was stronger in rural areas as compared to cities and other areas with higher population densities. Unexplained district variation was substantial, comparable to that associated with health insurance. In policies to tackle inequalities in healthcare utilisation, addressing geographical factors such as service availability and infrastructures may be as important as improving compositional factors like health insurance.
