Population trends in Mantoloking show a recovery and growth pattern. In 2013, the population was 968 residents. It peaked in 2020 with 1,520 residents and slightly decreased to 1,417 residents in 2022. The population growth from 2013 to 2020 may be attributed to recovery efforts following Hurricane Sandy in 2012, which significantly impacted Mantoloking.

Mantoloking is becoming slightly more diverse but remains less diverse than New Jersey as a whole. The high median income and predominantly white population suggest that Mantoloking may be experiencing slower demographic changes compared to more urban or suburban areas of New Jersey. The increase in the Asian population from 2% to 10% is notable and might reflect broader trends of Asian immigration or migration to affluent suburban areas in the Northeast.

The economic resilience of the area, maintaining high median incomes even through national economic challenges, suggests that Mantoloking remains an exclusive and desirable location. This economic stability may be a factor in the slow pace of demographic change, as high property values and living costs could limit accessibility for more diverse populations.

In conclusion, Mantoloking is showing signs of increased diversity but remains a predominantly white, affluent community with a "Low Diversity" classification. The subtle demographic shifts and economic fluctuations over the past decade suggest a community in slow transition, balancing its exclusive character with gradual diversification trends.
