The table illustrates the percentage of population growth, the number of average birth per woman and life expectancy in countries with different income levels over a 4-year period from 2000 to 2004.
A notable feature is that percentage of population growth, the number of average birth per woman decreased modestly. In 2000, high income countries had a 0.8% population growth, which is slightly lower than 2% in low income countries. After that, both proportions fell to 0.7% and 1.8% respectively. Meanwhile, the population growth in middle income countries retained at 0.9% throughout the period. As for average birth per woman, middle income countries are 2.2 in 2000, slightly lower than 3.9 in low income countries. Subsequently, both value saw a mere decrease reaching 2.1 and 3.7 respectively, while that of high income countries stayed the same at 1.7.
Regarding the life expectancy, it changed dramatically. In 2000, it was 78-year-old for high income countries, considerably higher than that of low income countries at 58.1. Followed by a modest increase to more than 0.4 years. Middle income countries, in contrast, showed a dramatic increase from 69.1 to 70 during the 4-year period.
Overall, it is evident that low income countries’ percentage of population growth, and the number of average birth per woman ranked first throughout the period. Furthermore, all the figures climbed except for population growth.
