Deciphering Population Pyramids
http://www.prb.org/Multimedia/Video/2009/distilleddemographics1.aspx
In this first video, "Deciphering Population Pyramids," PRB senior demographer Carl Haub shows how population pyramids give us a snapshot of a country's demographic profile. But what do they tell us about a country's past and future? "These videos not only show that demography can be exciting, but also highlight how population trends and issues affects the well-being of us all," says Haub. "Fertility, mortality, and migration—along with other demographic issues—play a major role in determining what kind of opportunities and challenges people face in their communities and countries."

Stage OneHigh Birth RateHigh Death RateResult: slow growth ratesPre-industrial, hunter/gatherer societies
in remote areas.

Stage TwoHigh Birth RateLow or Falling Death
RateResult: Rapid Growth
RateVery LOW Standard of
LivingFound In Least

Stage ThreeModerate to High Birth RateLow Death RateResult: Explosive Growth RatesCauses a large population increase, but
standard of living remains low Developing Countries and the Newly
Industrialized CountriesFound In Countries:
MexicoSoutheast AsiaMiddle East

Stage FourLow birth ratesLow death ratesResult: slow or no
growth ratesPopulation slowly
increases, with a high standard of living

Stage FiveNegative Birth Rate
NEGATIVE or NO GROWTH
Low Death RateResult: No growth, even
population lossPopulation begins to
shrink, usually has a high standard of living

Rapid, Slow, Zero and Negative Population Growth

High fertility and mortality = broad base
Low fertility and mortality = narrow base
