Greater Boston continues to be further defined as a dense urban core surrounded by a large collection of growing, mixed-use environments served by high capacity alternatives to auto transportation. Data suggests this trend, now also observed in most other major American urban agglomerations, has been underway in Boston for the entirety of the 21st century. Since 2014, essentially all major occupant activity in Greater Boston has been transit-accessible. 

The development community has responded quickly to a desire of medium and high income earners to live near transit, in percentages not seen in more than 100 years. Larger tenants are increasingly advised at the highest levels by human resources managers emphasizing the importance of selecting locations that appeal to workers who prefer alternatives to private car commuting. A thriving job market and record low unemployment have empowered employees, which allows them to align their work settings with their accessibility preferences. 

Developers and investors increasingly view this shift toward transit as not just a phase, but a long term trend, with universal auto dependency likely having been the phase.
