A methodology for segregating rural-urban mortality estimates

" This study deals mainly in estimating rural/urban mortality differentials in countries where death registration by place of residence is nonexistent or inadequate. The methodology was applied to Philippine death registration data of 1975 and the result was compared to those estimates obtained by applying Brass, Sullivan and Trussell techniques on the 1978 World Fertility Survey data of children ever born and children still living. Basically, the methodology allocates death registration data to rural and urban areas by applying to each geographic unit several indices of urbanization. This is possible when death registration in developing nations is tabulated by geographic units, such as province, region, state, island, etc. The underlying assumption is that some geographic units are more urbanized than others. The process involves identification of these units and combining them into urban areas. This likewise implies that the remaining areas can be combined as rural." (SUMMARY IN FRE AND ITA)
