The bar graph illustrates the relative percentage contributions made by the agricultural, industrial and service sectors to the Indian economy between 1960 and 2000.
Over the whole time period, the significance of agriculture declined steadily while services grew in importance decade by decade. A different patterned emerged for industry, which initially showed a slowly increasing percentage but then plateaued from 1980 onwards.
In 1960, agriculture contributed by far the highest percentage of GDP, peaking at 62%, but it then dropped in steady increments to a low of 12% in 2000. The service sector, on the other hand, had a relatively minor impact on the economy in 1960. This situation changed gradually at first, then its percentage contribution jumped from 28% to 43% between 1980 and 1990. By 2000 it matched the high point reached by agriculture in 1960, showing a reversal in the overall trend.
Industry remained a steady contributor to India’s wealth throughout the period. As a sector, it grew marginally from 16% in 1960 to exactly a quarter in 1980 then remained static for the next two decades, maintaining a constant share of the overall GDP.
