There&#x27;s a lot of history, even if sometimes accidental history, in why certain industries are so concentrated where they are. But there does seem to be a natural tendency to concentrate in many cases. For example, the Kendall Square area of Cambridge is pretty much non-stop pharma&#x2F;biotech construction. MIT is part of the reason in that case but I&#x27;m sure it&#x27;s not the only one.<p>Of course, there are often Tier 2 locales for a given industry that have less of a concentration but still have a reasonable hiring pool and&#x2F;or people willing to relocate there (plus remotes). They may not be as in-demand as the center of the given industry, but they can be a lot cheaper or attractive in other ways. In tech, the housing pains of the Bay area are arguably the perfect storm of historical happenstance, a great climate for the most part, and constrained geography.
