Literacy rate in India after Independence


A report based on the graph can be like this:
The above bar graph represents the literacy rate in India after independence. Spread over a duration of 60 years (from 1951 to 2011), the rate of literacy has attained a steady growth from just 16.7 percent in 1951 to a considerable 74.04 in 2011. As can be ascertained from the graph, in the initial years of independence, i.e, during the first 30 years , the growth rate has been below ten percent.
There is a big leap in the 1980s as there is an all time increase of 14 percent. The next decade has also witnessed a growth of about 13 percent. The rate has witnessed a fall in the next decade as it is less than 10 percent. The policies of the Governments and their implementation might be the reason for the unsteady trend in the growth of literacy rate. However, the overall growth is promising since it is about to cross 75 percent in 2011.
