Population Pyramids :D

There are different types of Pyramid Shapes:


Stage 1 Expanding: High CBR, rapid fall in each upward age group due to high CDR, short life expectancy.


Stage 2 Expanding: High CBR, fall in CDR as more individuals live to middle age, slightly longer life expectancy.


Stage 3 Stationary: Declining CBR, low CDR, more individuals live to old age.


Stage 4 Contracting: Low CBR, low CDR, higher dependency ratio (those that cannot work), longer life expectancy.


LECD tend to be stage 1 or 2, while MEDC are in stages 3 or 4.
