Objective: The aim of this study is to assess the performance of Lincoln – Petersen,Chapman and Bailey two source Capture Recapture methods. Material and Methods: TheCapture Recapture methods were applied with simulation studies on data obtained from surveyto estimate the population size of families with at least one disabled individual in Turkey withsmall, medium and large samples, and to compare the performance of these estimators with differentsample sizes with Root Mean Squared Error (RMSE) measure. Results: From the comparisonpart of the mentioned Capture Recapture methods, the Lincoln - Petersen method providesmore reliable results than Chapman and Bailey methods in small sample size one and two, butundefined when there were no element recaptured in sample two. Chapman and Bailey methodsprovides better estimates than Lincoln – Petersen method when dealing with big sample oneand small sample two. When working with big samples are all the three estimators mentioned inthis study provides better estimates with least RMSE. Conclusion: At the conclusion part of thisstudy we remark that, when dealing with small samples I and II Lincoln – Petersen should beconsidered but when no element recaptured in the second sample researchers should considerChapman and Bailey methods as alternative. When dealing with big size sample I and small sizesample II Chapman and Bailey methods should be considered and when both samples are largeall the methods discuss in this study can be considered.
