More About Popolation Pyramids

Today in class we reviewed the rest of the population pyramid by TED.  I personally really enjoy watching ted talks which is when successful people talk about things.  In the rest of the video they where talking about how some of the parts in the pyramid represented their history.  For example, when the population in china made a rule that the only one child per woman was allowed.  It showed a fairly large gap in the pyramid.  Later we reviewed countries like Qatar and Saudia Rabia.  There is a huge amount of more men then women. I think this is because of the oil.  Also one thing about the Pyramid was that if there was a huge amount of people in the 0-4 age range and a lot less in the others the birth rate is goin up really high.  The United States is increasing slowly. Although it would probaly be going down if we didn't have so many immagrants.
