India’s economy is expected to grow by 6.9% in 2011-12, the slowest pace of expansion in three years, dragged down by sluggish industrial growth and a decline in the mining sector. Data released by the Central Statistics Office on Tuesday showed growth in 2011-12 is estimated to be a shade below the 7%-7.5% being projected by policymakers and well below the 9% estimated last year. This is the slowest pace of growth since the 2008-09 global financial crisis, which pushed down India’s gross domestic product growth to 6.7%.
