The data illustrates population growth, average birth per women, and life expectancy at birth for high, low, and middle income countries in 2002 and 2004.
Looking from an overall perspective, population growth in countries with low income accounted for the highest percentage, while residents in high income countries have the most life span. Notably, in spite of having low income, the highest birth per woman was recorded in these countries.
To begin with, the population growth for low income nations decreased from 2% to 1.8% between 2002 and 2004, whereas that of high income countries increased by 0.1% during the same period. It is evident that in middle income countries population growth remained constant at 0.9%.
Remaning average birth, countries with low income experienced decrease from 3.9 to 3.7 per woman, similarly middle income states saw a drop of 0.1 per women. However, this average stayed roughly the same at 1.7 per women in high income countries. Finally, in terms of life expectancy, as expected high income countries had the largest life span at just under 80, followed by middle income and low income countries with almost 70 and 60 years, respectively.
