Gentrification occurs when three things happen: 1. new people move into a community, 2. that community is not building enough housing to absorb the new people, and 3. the now-apparent shortage means that those with the ability to pay the highest rents are the ones that remain.

Because the entire Bay Area has a housing shortage, there’s almost nowhere you can move where you won’t be contributing to gentrification. But it can be more or less acute. The greater the disparity between the incomes of the people moving in and the people already there, the faster displacement will occur in that community and the more acute the impacts of gentrification will be there.
