2.) It took about 10,000 years for the world population to reach about 1 billion
      In 2011, the population of the world will be about 7 billion

3.) Japan has the highest life expectancy in the world (82.6 years)
     United States is #38 in the world (78.2 years)
     Switzerland has the lowest life expectancy in the world (31.9 years)
     In almost every country, women live (a little bit) longer than men do.

4.) The rate of natural increase (RNI) can be produced by subtracting the death rate from the birth rate, then dividing by 10; this gives us the annual natural natural growth rate for a country or region. (in percentage form)

5.) A person entering the country is net immigration

      for a population to remain the same, the TFR must be 2.1 (higher: population rises; lower: population falls)
     the world TFR: 2.54; US TFR: 2.05
