MIT grads often choose Cambridge for startups

CAMBRIDGE – While Boston's colleges and universities are thought to provide engines for much of the city's urban and economic development, across the Charles River, the Massachusetts Institute of Technology has, of course, backed up assertions of its impact with numbers.
In an updated Entrepreneurship and Innovation at MIT report, the school says its alumni have started 30,000 active companies since the 1930s, and nearly a third of the domestically based enterprises were set up in the Bay State. Respondents to a survey of more than 100,000 alumni reported starting 1,691 companies in Massachusetts, which indicates MIT grads have founded about 7,000 businesses in the state over the years, according to the report.
