More than 95% of the natural increase is clustered in developing nations
Why is Global Population increasing?
Total Fertility Rate- amount of children a woman will have in their child bearing years.
2.42 is the worlds Total Fertility Rate
TFR exceeds 5 in some African countries, while its only about 2 in European countries.
Infant Mortality Rate- deaths of infants under one year of age
expressed as per 1,000 births instead of a percentage
IMR usually about 50 in sub-Saharan countries and about 5 in developed countries
Developed countries have lower rates of natural increase, crude birth rate, total fertility rate, and infant mortality compared to developing countries
Fertility and mortality vary not only between countries but within a country
Population pyramids explain a countries population structure
Dependency Ratio- Number of people too young or too old to work compared to the population eligible to be a part of the work force
