Population-level census

We aimed to exhaustively sample two independent comparison groups across the 13 village clusters to compare population-level outcomes before and after implementation of the intervention. These consisted of all married women of reproductive age (15–49 years) in the catchment area population, who had given birth within the 2 yrs prior to the survey date. These data were collected in the catchment area population before implementation of the intervention through a household census and after a full year of implementation. The pre-implementation survey was conducted from November 2014 to February 2015. The follow-up survey was conducted March 2016 to July 2016.
