In 2012, Cambridge witnessed groundbreakings for over 1.8 million square feet of new construction, almost all of it in Kendall Square.
Meanwhile across the river in Boston, three million square feet of new construction is underway right now in their innovation district, with another 20 million planned.
This deserves an exclamation point! These are very large numbers in very small geographic areas. If ever there were statistics that screamed "Cities are the 'it' thing in 2013", these would be them.
We're a long way from 1975.
