Riva remains a predominantly white, affluent community with "Low Diversity." There are subtle signs of demographic shifts. The area's high incomes and growing population suggest it remains economically robust. The gradual increase in Hispanic residents and the emergence of multi-racial identities indicate a slow but steady diversification, potentially reflecting broader national trends towards increased suburban diversity. These changes are occurring at a much slower pace than in many other suburban areas across the country.
