Infographic: Core sector growth slows down

India's annual infrastructure output growth slowed to more than a year's low of 1.8 per cent in January, mainly dragged down by a sharp slowdown in crude oil and natural gas production, government data showed on Monday.

The output had expanded 2.4 per cent year-on-year in December.

The infrastructure sector, which comprises coal, crude oil, oil refining, natural gas, steel, cement, electricity and fertilisers, accounts for 37.9 per cent of India's industrial output.
