In this study unmet need for family planning in Turkey is analyzed employing the standard formulation of unmet need with a different approach. The purpose of the study is to explore the difference in the size of unmet need when it is estimated for non-users and for users of traditional method who have intention for using a modern method. An alternative approach is preferred in view of the fact that the method-mix of the country affects the magnitude of the estimated unmet need. Thus, to take country-specific situation in family planning method use into account enables to estimate the extent of potential demand for family planning in a more realistic way. The analyses in this study is based on married women aged 15-49 from the 2003 Turkey Demographic and Health Survey. The results put out that in general, the unmet need estimated with the inclusion of women who want to replace their traditional family planning method with a modern one (18.9 percent) reflects a relatively large group of unmet need for contraception compared to that of estimated with the standard formulation (7.1 percenta). Difference reveals itself not only in the magnitude of unmet need but also for the selected background variables such as region, type of place of residence, education and age. It is observed that the method-mix of the country affects the magnitude of the estimated unmet need.
