Mathematica's evaluation will assess the impacts of the T&D activity and the financing scheme initiative on communities and households using quantitative data from the community and households surveys. Mathematica will investigate whether the compact activities led to improved economic, educational, and health outcomes at the household and community levels. A case study of the relationship between the T&D activity and financial outcomes among enterprises in a sub-set of communities in the Tanga region will be conducted using data from the enterprise survey. For the T&D evaluation, Mathematica is using a difference-in-differences design. For the financing scheme evaluation, a cluster random assignment design (with communities as the unit of assignment) is being used. The National Rural Electric Cooperative Association (NRECA) International, a U.S.-based firm, conducted the baseline community, household and enterprise surveys in 2011. At baseline, NRECA surveyed 725 communities, 10,298 households, and 59 enterprises. Follow-up surveys are expected to be carried out during the summer and fall of 2015. The data files provided here include the cleaned, anonymized data from each survey, as well as files containing the variables constructed for analysis.
