10/7 class

today we discussed birthrate, death rate, TFR, immigration/emigration, net migration rate, and pull/push factors.
notes from class:
1.8 people die per second.
there are over 6 billion people in the world.
US birthrate is 14 births per 1000 people.
US death rate- 8 per 1000 people.
TFR- average number of children a woman will have in her lifetime.
if the TFR is 2.1 then the population will stay the same.
immigration/emigration can change the population.
US net migration rate is 4.32.
Canada's net migration rate is 5.63.
Mexico's net migration rate is -3.61 (more people leave than enter).
pull factor- makes you want to come to a country (example: freedom of speech, political freedom).
push factor- something that makes you want to leave the country (example: bad health care).
