demographic transition
process that has developed over history. went from high CBR and and CDR and low RNI to low CBR and CDR and high RNI (and now moderate RNI) resulting in a higher population.
demography
study of population characteristics
total fertility rate (TFR)
the average number of children a woman will give birth to
rate of natural increase (RNI)
the percentage in which a population will grow each year
