For 2016-17, factory output grew by 5 per cent as against 3.4 per cent in the year-ago period.
On the other hand, IIP growth based on the old series (2004-05 base year) was 2.5 per cent in March compared to 0.3 per cent a year ago. Similarly, the figure for 2016-17 was 0.7 per cent as against 2.4 per cent in the previous fiscal.

Electricity generation too slowed to 6.2 per cent, from 11.9 per cent in March 2016.
The mining sector, however, expanded by 9.7 per cent in March 2017 compared to a growth of 4.7 per cent in the year- ago month.
This, it said, is attributable to shifting of base to a more recent period, increase in number of factories in panel for reporting data, exclusion of closed ones and inclusion of new items and exclusion of old ones.
The coverage of the new series of IIP is limited to the organised sector only.
At a broad level, the new series has a total of 809 items in the manufacturing sector.
In the item basket, 149 new products like steroids and hormonal preparations, cement clinkers, medical or surgical accessories, pre-fabricated concrete blocks and refined palm oil have been added.
