The tables provides readers information about the growth of population, average birth per female, and life span at birth in nations with three types of income levels, namely high income, middle income, and low income countries in the years 2000 and 2004.
Overall, low income nations had the highest figures in terms of population growth and average birth per woman, with an exception of life expectancy at birth in all the two years examined, while an opposite trend was true for high income countries throughout the period. It is also clear that life expectancy at birth and population growth witnessed an increase in all the three kinds of countries given, while different trends were seen in the figures for the remaining categories.
Looking first at the population growth, this data in low income countries remained the highest in 2002 and 2004, at 2.0% and 1.8% respectively. While the figure for middle income nations remained unchanged throughout the period, increasing 0.9%, this data in high income countries in 2002 was slightly higher than that in 2004, with respective figures of 0.8% and 0.7%.
Regarding average birth per woman, this figure remained stable in high income countries, at 1.7. It is important to note that the average birth per female in low income countries were always higher than that in middle income ones in both years, with respective figures being 3.9 compared to 2.2 in 2002 and 3.7 in comparison with 2.1 in 2004.
Finally, 78.0 was the life expectancy at birth in high income countries in 2002, followed by a slight rise to 78.7 in the next 2 years. Interestingly, the trend of this data was reversed with that of average birth per woman, when the life expectancy in middle income nations were always higher than that in low income ones, with respective figures of 69.1 compared to 58.1 in 2002 and 70.0 in comparison with 58.8.
