The oppposite is true statewide, where the birthrate has steadily decreased since 1998. As a result, the Somerville birth rate has consistently exceeded the Massachusetts rate since 2007.

Collision Safety

Safety on the streets of Somerville is a priority for both the City and its residents. The following maps shows the location of collisions involving pedestrians and cyclists from 2010 through August of 2015. A larger dot, which indicates an intersection with more crashes than others, is usually indicative of more activity at that intersection. The City takes this data seriously, and strives to eliminate as many safety hazards as possible.
