Consider this Boston Business 101 — your guide to our region’s key industries and major employers.

The key industries

There are five key industries that represent ~62% of Boston’s economy, based on the most recent 2021 data from the City of Boston. We’ve listed them in order of employment numbers.

Healthcare and Social Assistance | 152,936 employees
This one comes as no surprise, considering that Boston is home to top research and teaching hospitals — we’re looking at you Boston Medical Center, Boston Children’s Hospital, and Brigham and Women’s Hospital. There are also plenty of community-based centers keeping Bostonians healthy.

Professional, Scientific, and Technical Services | 116,365 employees
Since this sector requires a high degree of expertise, this is where many graduates from Boston’s higher education institutes wind up working. Think: Cambridge’s strong biotech scene or the many tech startups around Boston.

Finance and Insurance | 102,050 employees
This industry saw significant job growth prior to the pandemic, as its companies tend to require commercial office space. Still, the finance and insurance space employs lots of Bostonians across companies like Fidelity Investments and State Street Corporation.

Government | 74,665 employees
That’s a whole lot of folks working for our local government. These jobs range from Boston’s City Council members and public health staff to archaeologists and school traffic crossing guards.

Educational Services | 66,981 employees
Considered an area of specialization for Boston, our city has an employment share three times the national average for education services. Area colleges include Boston University, Northeastern University, Boston College, and Tufts University — just to name a few.
