The median income in Belmar has shown overall growth, albeit with some fluctuations. From 2013 to 2019, there was a steady increase from $56,029 to $72,954, representing a 30% growth. However, there was a drop in 2020 to $63,777, likely influenced by the economic impacts of the COVID-19 pandemic. Since then, income levels have slightly recovered but remain below the 2019 peak. The population growth and increasing diversity coincided with the period of rising median incomes up to 2019.
