Gentrification is a process where wealthier people move into a neighborhood, often leading to rising property values and living costs. This can improve local amenities, like parks and shops, but it can also push out long-time residents who can no longer afford to live there. As new businesses open and the area becomes more desirable, the original character of the neighborhood may change. This can create tension between newcomers and existing residents, as the cultural landscape shifts. Communities like Brooklyn and San Francisco have experienced significant gentrification, sparking discussions about housing, equity, and community identity.
