todays class

today in class we went over the population pyramid some more and looked at each state or countries birth rate and population growth. the united states population in the 1950s was as low as 200 million people including its birth rate which this all was after world war 2. we looked at the worlds population in that time and its population was 2 billion and the birth rate was at 7.2% which is very high. now today its population is at 7 billion which the birth rate wasn't as big but it was consistent for the past 10 years.
