Today was a ketchup day! (makes me hungrey thinking about it)

Mr. Schick told us to go in our books to pg. 22 and look for Demographic Transition.

Well i found it and i found out what it is. Demographic Transition is a four-stage conceptualization that tracks changes in birthrates and death rates through time as a population urbanizes.

Stage one is characterized by birthrates and death rates. Stage two as death rates decline. Stage three is characterized by a decline in birthrates. The transition ends with low growth from a relative balance between low birhtrates and death rates.
