This study examines factors influencing contraceptive use among married women aged 15-49 in Pakistan using data from the Multiple Indicator Cluster Survey (MICS). This research aims to identify the demographic, economic, and sociocultural factors contributing to this disparity, focusing on the four provinces (Punjab, Sindh, KPK, and Balochistan). The study employs secondary analysis of data from over 103,000 women, exploring the association of CPR with variables such as age, education, economic status, fertility preference, and internalized patriarchy. Geographically, 40.9% of the sample was from Punjab, 23% from KPK, 18.8% from Balochistan, and 17.3% from Sindh, with 72.3% residing in rural areas and 27.3% in urban areas. Findings contribute to understanding provincial disparities and highlight the need for localized, culturally sensitive family planning strategies in Pakistan. The study calls for targeted interventions to improve birth control use among rural, less-educated, and poorer women, especially in Sindh and Balochistan.
