The population data for the zip code 07021, corresponding to Essex Fells in New Jersey, reveals a stable and consistently suburban population density over the past decade. With a land area of 1.48 square miles and a population of 2,670 in 2022, the population density stands at 1,804.05 people per square mile, placing it firmly within the suburban classification range.

Throughout the years from 2010 to 2022, the population has remained relatively steady, fluctuating between a low of 2,401 in 2020 and a high of 2,670 in 2022. This stability suggests a well-established suburban community with minimal significant urban development or drastic demographic shifts during this period.

Given the suburban population density, it can be inferred that the lifestyle in this zip code is likely family-oriented, with access to amenities such as schools, parks, and shopping centers. The estimated 1,022 housing units in 2022, based on the national average household size of 2.61, further support the notion of a predominantly residential area with a mix of single-family homes and some multi-family dwellings.
