Boston has lost about a third of it’s population. San Fran the same. They are depopulating.
I’m not sure of the demographics but I believe Boston anyways, is getting older. In short young people are not moving in and having young children.
Boston might not be dying, but it’s fading.

Furthermore many of the poor overpopulated neighborhoods have been gentrified by less populated wealthier people. Compared to my youth during the 60’s and 70’s, Boston is thriving. Boston is getting younger as well. San Francisco population 808,976. Highest ever.
