Consequent to gentrification, the average income increases and average family size decreases in the community, which sometimes results in the eviction of lower-income residents because of increased rents, house prices, and property taxes. This type of population change reduces industrial land use when it is redeveloped for commerce and housing. In addition, new businesses, catering to a more affluent base of consumers, tend to move into formerly blighted areas, further increasing the appeal to more affluent migrants and decreasing the accessibility to less wealthy natives.
Urban gentrification occasionally changes the culturally heterogeneous character of a community to a more economically homogeneous community that some describe as having a suburban character. This process is sometimes made feasible by government-sponsored private real estate investment repairing the local infrastructure, via deferred taxes, mortgages for poor and for first-time house buyers, and financial incentives for the owners of decayed rental housing. Once in place, these economic development actions tend to reduce local property crime, increase property values and prices and increase tax revenues.
