Indian economy is estimated to contract 7.7 per cent in 2020-21 compared to 4.2 per cent growth in the previous fiscal, mainly on account of the impact of the Covid-19 pandemic.

As per the first advanced estimates of the national income released by the National Statistical Office (NSO) on Thursday, there was a contraction in almost all sectors with the exception of agriculture.

"Real GDP or GDP at Constant Prices (2011-12) in the year 2020-21 is likely to attain a level of Rs 134.40 lakh crore, as against the Provisional Estimate of GDP for the year 2019-20 of Rs 145.66 lakh crore... The growth in real GDP during 2020-21 is estimated at -7.7 per cent as compared to the growth rate of 4.2 per cent in 2019-20," it said.

In the current fiscal, the manufacturing sector is likely to see a contraction of 9.4 per cent whereas growth was almost flat at 0.03 per cent in the year-ago period.

The NSO estimates significant contraction in 'mining and quarrying', and 'trade, hotels, transport, communication and services related to broadcasting'.

The agriculture sector is estimated to see a growth of 3.4 per cent in 2020-21. However, it will be lower than 4 per cent growth recorded in 2019-20.

The economy contracted 23.9 per cent in the first quarter and 7.5 per cent in the second quarter.
