Gentrification is typically the result of investment in a community by local government, community activists, or business groups, and can often spur economic development, attract business, deter crime, and have other benefits to a community.  Oh yeah…, despite these potential benefits, urban gentrification often, intentionally or unintentionally, is generally believed to result in population migration as poor residents of a neighborhood are displaced by wealthier newcomers, though studies have shown this not necessarily to be the case.
