Five Stages of Demographic Transition ° Stage2 High birth rates, declining death rates rising growth rates More food supplies, improved sanitation(water) and access to basic health care, which increase life span and reduce childhood mortality Started since the Industrial Revolution in the late 18th century and ended in the mid-20th century in Europe Started in developing countries since the 1950s 60s and developed substantially faster much of Sub-Saharan Africa today some countries of asia (Afghanistan etc)
