The Côte Sud Initiative’s Integrated Baseline Assessment is a multidisciplinary study that covers social and economic aspects of rural dwellers in Haiti. This report provides an integrated multi-sector analysis for ten communes in the southwest coast of the South Department of Haiti, designed to serve as a baseline for a larger ongoing monitoring platform. The purpose of the baseline study is to collect statistically significant evidence of the social and economic conditions of the population at the microscale (household) level. It will also provide evidence of the current state of the infrastructure and services offered, at the regional scale. The new data contained within this study is meant to inform decision makers, guide policymakers and support ongoing project design.
