While Bengaluru tops the charts, Hyderabad has been ranked number 7 and makes a surprise entry, scoring highly on long-run growth potential, although it scores less on other socio-economic factors and does not yet match Bengaluru as a source of talent. As per Colliers Research, about 56 million square feet (5.2 million sq m) of office space, Hyderabad is only about 40% of Bengaluru’s size. However, development is proceeding apace, with total stock set to increase by 33 million sq ft or 60% by 2021.
