A brief comparision of the fertility and mortality rates of Africans in various countries
MetadataShow full item record
The most frequently used measures of the fertility and mortality of a population are the crude birth and death rates and the infant mortality rate. These are normally based on (i) the number of births and deaths obtained from a comprehensive birth and death registration system; and (ii) census figures, or estimates based on censuses, of the total population. The reliability of the resulting crude birth and death and infant mortality rates depends on the completeness of the registration system and the accuracy of the basic population total.
