today in class we watched a video about global health. we learned that the world used to have a very low income and life expectancy. the life expectancy is the x-axis and it goes from 25-75 years. the y-axis is the income and it starts at 400-40,0000.400 means they at sick and poor. 40,000 means they are rich and healthy. the life expectancy in 1810 was under 40 yrs. in every country besides U.K. and Netherlands. when a countries industrialization increases so does the life expectancy and income.in 1948 the graph was as wide spread as it has ever been and there is countries that there life expectancy is over 75 and has an income average of 40,000 and there is some areas that have a life expectancy just over 25 and the only make 400 dollars of income.

U.S. #42 79.68 total- 77.32 men and 81.97 women. lowest Chad 49.81 total- 48.64 men and 51.03 women. we also learned about crude birth rate, which means the number of births per 1,000 of the population. Also we learned about the crude death rate, which means the number of deaths per 1,000 of the population. we learned about rate of natural increase which is produced by subtracting the death rate from the birth rate. this gives us the annual natural growth rate in percentage form-for a country or region. the net migration rate is 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. this is written as a...
