The demographic transition model consists of five stages:
 * 1) __Low-growth stage :__high birth rate and high death rate lead to a population that varies over time, with little long-term population growth.
 * 2) __High-growth stage:__high birth rate and declining death rate lead to sustained and significant population increase.
 * 3) __Moderate-__g__rowth stage:__declining birth rate combined with already low death rate lead to continuing population growth.
 * 4) __Low-growth or stationary stage:__ low birth rate and low death rate lead to a very low rate of growth.
 * 5) __Declining population:__ very low birth rate and low death rate lead to decreasing population.


 * “The __transition__ in the demographic transition occurs in stages 2 and 3, when death rates decline and then birth rates decline. When the death rate and birth rate fall, the country transitions from a high growth rate to a low or sustained growth rate. “ textbook __Human Geography: People, Place, and Culture__ De Blij, page 52.**


 * __ Further break down: __**
 * ** Stage 1: **
 * ** Epidemics and plaques keep death rates high **
 * ** Famines **


 * ** Stage 2: **
 * ** Population explosion (less deaths, birth rates still high) **
 * ** Life improvement : ex. Industrial Revolution **


 * ** Stage 3: **
 * ** Continuing decreasing death rates, birth rates also decline **
 * ** Greater urbanization, wealth, medical advances **
 * ** Women delay marriage and child bearing **
 * ** Contraceptives and abortion **


 * ** Stage 4: **
 * ** Low TFR **
 * **Women are the most educated and involved in the labor force**
 * ** Stage 5: **
 * ** Very low TFR **
 * ** Low death rate **
 * ** Family planning and good health **
 * ** Improved status for women **
 * ** Later marriages **
