The development and structure of Brazils population.

An almost insuperable obstacle to the studies on Brazilian demography is the incomplete registration of births and deaths and the negligence of registration officers who often omit to notify the central statistical service. However the data collected in the 1940 and 1950 censuses and the information obtained in some areas where registration is adequate have been successfully used to give an adequate picture of the demographic position. The principles and methods of this work have been already explained in international publications and will therefore not be discussed here; only the main results will be given. (excerpt)
