Main Article Content
The present research deal with post two stratification analysis for vaccinations data of MICS5 in Sudan. In order to guarantee more precision for estimated indicators: percentage of Child ever given BCG, Polio, PENTA and Measles or MMR vaccination. State and mother education level are determined as two stratification variables since the correlation between them is small and the correlation with target indicators are some of size. So the two way stratification analysis for the four indicators gives more precise estimates the post stratification with high relative efficiency.
