This strategy details the work of The Nigeria Urban Reproductive Health Initiative (NURHI) in engaging urban poor citizens to build a base for mobilization for collective action through community-based structures. NURHI was designed to increase contraceptive use in selected urban sites in Nigeria, with a focus on the urban poor. Through a strategic combination of service delivery, communication, social mobilization and advocacy inputs the NURHI project aimed to increase demand for and supply of family planning, ultimately leading to long-term market driven sustainability. In 2012 a midterm evaluation (Measurement, Learning & Evaluation of the Urban Health Initiative: Nigeria 2012 Midterm Survey) showed considerable improvements in Family Planning knowledge and behavior across the four Nigerian cities. The evaluation showed increases in the knowledge of family planning methods from baseline to midterm across all cities for both men and women. More than 98 percent of men and women have correct knowledge (spontaneous or probed) of at least one family planning method at midterm. The largest increases were observed in Kaduna — a 23 percentage-point increase for women and a 19 percentage-point increase for men.
