•  over 6.8 billion people on the planet right now
• 90% of this population growth takes place in the developing countries of Africa, South and East Asia, and Latin America
• increasing by over 80 million per year
• by 220,980 per day(in 2009)
• 14,000 births per hour
• As time went on since the first billion people it started rearching then next billion people faster.
• women are expected to live longer because they don't have as hard jobs. Women are more likely to go to the doctor when something is wrong cause men just try and suck it up.     
• Life expectancy- the average number of years to be lived by a group of people born in the same year
• High:  Japan  (82.6 total:     79.0 men,  86.1 women)
• # 38:  U.S.    (78.2 total:     75.6 men,  80.8 women)
• Low:  Swaziland  (31.9 total:     31.6 men,  32.2 women)
• crude birth rate: number of births per 1000 of the population
• crude death rate: number of deaths per 1000 of the population
• rate of natural increase (RNI) 
  • produced by subtracting the death rate from the birth rate, then dividing by 10
  • this gives us the annual natural growth rate - in percentage form -  for a country or region
• Net Migration Rate: the difference between the number of persons entering and leaving a country during a year
• an excess of persons entering the country is net immigration 
  • written as a positive number
  • example: Canada has 5.63 migrants per 1,000 population
• an excess of persons leaving the country is net emigration
• written as a negative number
• example: Mexico has -3.61 migrants per 1,000 population
• More immigrants the number is positive.
• More emigrants the number is negative
•  push forces
  
  • civil war
  • environmental degradation
  • unemployment
  • religious or ethnic persecution
  • Don't have good medicine or vaccines.
• pull forces
  • better economic opportunity
  • better health services
  • religious freedom
  • political freedom
  • education
• More people migrating today because there are some many more people.
• TFR: average number of children born per woman
• for a population to remain the same, the TFR must be 2.1
• higher than 2.1: population rises
• lower than 2.1: population falls
• World TFR: 2.54
• US TFR: 2.05 Our population is going up because more people are moving to the US.
• Europe's TFR: 1.45 This is low, they don't have people to fill the jobs.
• Africa's TFR: 5.14
• Germany is begging people to have kids. They realize what serious problems they will have if they don't have enough people.
