نظراً لأهمية المسح البعدي لتعديل بيانات التعداد السكاني ونظراً لعدم إجراؤه في اليمن تقترح الدراسة بالاستعاضة عنه بالبديل الذي تقترحه وهو استخدام التوزيعات الاحتمالية لتعديل بيانات التعدادات السكانية وخاصة توزيع وايبل في تعديل بيانات التعداد السكاني لليمن لعام 2004، ومن ثم يمكن تقدير بعض المعلمات الديموجرافية في ضوء بيانات التعداد المصححة التي تساعد في عملية التخطيط والتنمية في جميع القطاعات الاقتصادية والتعليمية والقوى العاملة والصحة وتنظيم الأسرة.
Census date are always subject to sampling and non-sampling errors. Non-sampling errors always exist in census data and they are usually due to lack of coverage and to insufficient contents. Thus, census data should be "corrected via Post enumeration surveys (PES), which are difficult to conduct due to cost and effort factors. Thus, some alternative techniques have to follow to correct census data. Probability distributions could be used for this process, and could be used for the estimation and projection of demographic indices that could be used in the economic, education, labor, health and family planning. Using ARENA program, and using four goodness of fit teats, the Weibull probability distribution proved to fit the 1994 census data for the Republic of Yemen. Data were corrected for age composition for both males and females for 1994. Projection of some demographic and vital statistics rates when the objective is a total fertility rate 2.8/ woman and for age composition are obtained for 1994 to2034 .Projected indices for 2004 are compared to indices obtained from the 2004 census, differences between projected values and actual indices of 2004 were negligible.
