The bar graph illustrates the contributions to India's economy made by three categories: agriculture, industry, and services from 1960 to 2000.
Looking at the chart in more detail, agriculture declined its importance gradually every decade, meanwhile, a reverse pattern was observed in the service sector.
In 1960, the percentage contribution of farming reached a peak of over 60%, which was about three times higher than that of the industrial and service sector. This figure lost its momentum and dropped steadily throughout 40 years and accounted for about 12% at the end of the survey.
By contrast, the significance of services went up slightly over the first 20 years, at 23% and 27% in 1970 and 1980. Then, this figure rose dramatically to around 45% in 1990 and peaked at over 60% in 2000, which was as high as that of the agricultural sector in 1960.
From 1960 to 1980, the contribution of industry to India's GDP increased modestly to about 25%, which was 8% and 4% higher than that of itself in 1960 and 1970 respectively. This proportion remained stable over the final 20 years of the survey.
