Trends and sociodemographic inequalities in the use of caesarean section in Indonesia, 1987-2017.

This study provides evidence of increasing trends in CSRs and widening absolute inequalities in CSRs across different sociodemographic groups of women in Indonesia. The context of increasing CSRs across society, however, may have resulted in more stable relative inequalities. Improving understanding of the drivers of these trends in Indonesia and, particularly, of women's and providers' perspectives and preferences for childbirth, should be prioritised to optimise the use of CS.
