Today in human geo class we talked about life expectancy. The life expectancy is the average number of years to be lived by a group of people born in the same year. In Monaco the population is very high. Woman have a longer life expectancy then men because men take more risks, they work more dangerous jobs and military. The crude birth rate: number of births per 1000 of the population. The crude death rate: number of deaths per 1000 of the population. Rate of natural increase (RNI) is produced by subtracting the death rate from the birth rate. This gives us the annul natural growth rate. Net migration rate is the difference between the number of persons entering and leaving a country durning the year. An excess of a persons entering the country is net immigration. An excess of persons leaving the country is a net emigration.
Today in human geo we watched another video. It was Hans Rosling he teaches global health. He made of graph. The X axis was life span and the Y axis was income. He showed the world separated by color dots. Europe was brown. Asia was red. Middle East was green. Sub-Saharan was blue. Americas was yellow. The graph started in year 1810. In 1810 all people were sick and poor and the life expectancy were 40 years old except for U.K. and Netherlands. As the years went on the life expectancy got higher and people got more money.
