Levels of contraceptive prevalence rate of the respondents having only daughters is found only 48.4, which is remarkably lower than the national average (62.4) because of son preference. The analysis reveals that son preference is variant regarding of place of residence and socioeconomic background. Son preference is stronger among illiterate, nonworking women and women above 40 years of age. Moreover, Muslim women have a strong son preference than their Non-Muslim counterparts.
