Demographic transitions: occurrence of prolonged and relatively permanent changes in population growth rates
The fundamental equation of demography indicates that a population grows or decreases in size as the result of the combined influence of births, deaths, in-migration, and out-migration
components method: birth and the other vital events are the components of—the “parts that constitute”—change
-
linear growth model: assumes that an equal percentage of persons is added to (or subtracted from) a population each and every year in the interval
-
-
r = (proportionate growth)/n, or as a percent, (percentage growth)/n
-
-
(B – D), births minus deaths, term is referred to as natural increase
(I – O), in and out migration, makes up net migration
upward, a shift from low to high rates of growth
stage 1 to stage 2: founding of modern science by Sir Isaac Newton and the widespread introduction of the earliest modern technologies of mortality control
downward, a shift from high to low rates
-
-
In Asia, Africa, and Latin America, mortality rates continue to decline much faster than birth rates, and this pattern is expected to continue for many years
-
-
-
The presence of easily accessible family-planning programs is an essential component in meeting the new demand for birth control method
