Greenwich remains a densely populated urban neighborhood. The current density suggests a compact urban environment, likely featuring mid-rise and high-rise residential buildings. This density typically supports various amenities within walking distance.

The neighborhood's population dynamics indicate potential factors influencing changes. Initial growth from 2010 to 2014 may be attributed to urban renewal efforts or increased urban living desirability. The subsequent decline could be due to changing housing preferences, economic shifts, or gentrification.

Greenwich has a historical context as a Philadelphia neighborhood. It is known for its diverse community and proximity to the Delaware River waterfront. These factors may influence its appeal and development patterns.

The estimated 791 housing units for the 2022 population, based on the national average household size, suggests a mix of housing types. Given the high density, these are likely predominantly apartments and condominiums.

Greenwich presents a dynamic urban neighborhood that has undergone significant changes. While densely populated, the population decline trend may be altering the community's character. This could impact local businesses, services, and community cohesion. Future urban planning and community development initiatives in Greenwich may need to address these demographic shifts.
