title: Factors affecting fertility of natives and migrants in urban Brazil.
abstract: Abstract   Modernization is expected to change the patterns of population growth of developing countries. The primary reason explaining the fast rate of population growth of these nations has been established as that of the reductions of mortality! which marks the first stage of demographic transition. The second stage in this process is the reduction in fertility which counterbalances lowered mortality and therefore reduces the rate of population growth. This latter phase has been achieved in modern industrial societies.
