Fertility preferences in Cambodia are examined with data from Cambodia Demographic and Health Surveys 2000, 2005, 2010 and 2014. The chapter contains brief reviews of trends in actual fertility during 1960s to 2014; measures of fertility preference used in Cambodia and extant studies on fertility preference in the country. It examines trends in wanted total fertility rate (WTFR) by age and education of women and men, province, and household wealth quintile. WTFR is lower than actual total fertility rate (TFR), but the gap between the two has narrowed down over time. However, large gaps between WTFR and TFR still exist in some of the provinces. WTFR is found to be a strong predictor of TFR when the provincial TFRs are regressed against provincial WTFRs. The chapter provides policy recommendations to further reduce desired fertility, increase the uptake of effective contraceptives and reduce unmet need for family planning.
