The line graph indicates the percentage of the literacy rate in North America, Asia, and Africa between 1930 and 2000.
Overall, it is clear that the three countries had increase points from 1930 to 2000. North America made up the largest proportion during the seventy-year period and Africa had the smallest number of people that can read and write their languages. The rate in Asia increased rapidly over the same period.
Looking at the graph more closely, one can see that the percentage of literacy people in North America accounted for the largest point among the three countries in 1930, at just under 70%. There was an increasing trend to 83% by 1980, but since 1980, the percentage started to decline slightly at the end of the period. The literacy rates in Asia was 39% in 1930. It is noticeable that the number of people in Asia who are literacy went up the most. As a result of that, in 2000, the rate of the literate people was almost the same with that in North America. Lastly, the percentage of Africa recorded the lowest point at the front of the research year at 15%. From 1950 to 1960, the figure was stable and slightly dropped from 1980 to 1990. At the end of the period, the proportion made up 40% of the total people in the country, which was about a half of the percentage of both North America and Asia.
