Today in class we talked about measuring population. Here are my notes:

crude birth rate- number of births per 1000 of the population
crude death rate: number of dearhs per 1000 of the population

rate of natural increase

•       prodiced by subtracting the death rate from the nirth rate
•       this gives us the annual natural growth rate- in percentage form- for a country or region

net migration rate: the difference between the numberof persons entering and leaving a country

IMMigration-entering a country

EMMigration-leaving a country

We also explored the CIA factbook. 

Mr. Schick's powerpoint said that in 2013 the US had 3.62 migrants. I found that in 2014 the US had 2.45 migrants. (in net migration rate)

Mr. Schick's powerpoint said that in 2013 Mexico had -3.11 migrants. I found that in 2014 Mexico had -2.99 migrants. (in net migration rate)

What I found interesting on the CIA factbook was that the smallest country in the world according to population is the Pitcairn Islands. The population there is 48 people. The industries there are postage stamps, handicrafts, bee-keeping, and honey. They do not have a military, their defense is the responsibility of the UK. I think we should go on a field trip there.
