• The one country with a negative RNI is Germany
• In most African nations the total fertility rate is high becuase most children don't survive, and so they have 4 or 5 in hopes that some will survive
• One can be an immigrant and emigrant, by moving to one country (immigrant) and leaving their own.(emigrant)
• Why do you migrate? Push and Pull factors: people are "pushed" out their own country by laws or resricted freedom, and they are "pulled" into a better country 
• Pull factors are the reason that the net migration is so high in some countries
• Population pyramid
• determines the age of the people in a population
• when you have a low amount of people in the lower age range that are the work forces nad have the timportant jobs, and a high amount of people in the bigger age ranges that need help, then it causes problems in the economy
• Germany had a low population rate, and they don't have as many people pouring into their country
