The main focus of this analysis is the economic impacts of the KALAHI-CIDSS project. It looks at the costs and benefits of seven major subproject (SP) categories that cover 1,175 completed and ongoing subprojects (e.g., domestic water supply [both pump and gravity], roads construction and improvement, elementary school buildings, barangay health centers, and day care centers). These seven major categories accounted for 82 percent of total subproject costs.
