The ZIP code 10021 in Manhattan, New York, has demonstrated a consistently high population density over the past decade, with the most recent data from 2022 showing a population of 39,118 and a density of 102,942.11 people per square mile within its 0.38 square mile area. This population density places the area firmly in the hyper-urban classification, which is characterized by extremely dense living conditions, skyscrapers, and extensive infrastructure.

The lifestyle in this hyper-urban environment is highly urbanized and cosmopolitan, catering to professionals and affluent residents who prioritize luxury, convenience, and proximity to major business districts. The area likely features high-end shopping, exclusive entertainment venues, and gourmet dining options. Living spaces in such densely populated areas are typically very small, often less than 500 square feet, emphasizing vertical living and premium amenities.

Given the estimated 14,987 housing units corresponding to the 2022 population and the national average household size of 2.61, it is evident that the area is dominated by multi-family residential buildings, such as apartments and condominiums, rather than single-family homes. This further reinforces the hyper-urban nature of the area, where space is at a premium and the focus is on maximizing the use of vertical space.
