Despite the population decrease, Shelltown maintains a high population density, indicating that it remains an urban neighborhood. The estimated 1,240 housing units for the 2022 population suggest a mix of housing types, likely including apartments and multi-family dwellings, to accommodate the dense population in a relatively small area.

Shelltown, being part of San Diego, benefits from the city's mild climate and proximity to the coast. This geographical advantage may influence the lifestyle of residents, potentially offering opportunities for outdoor activities and a blend of urban living with coastal amenities.

The demographic shifts observed in Shelltown over the past decade reflect broader trends seen in many urban areas, where population dynamics can be influenced by factors such as changing economic conditions, housing market fluctuations, and evolving preferences for urban or suburban living. As the neighborhood continues to evolve, it will be important to monitor how these population changes impact the local community, infrastructure, and overall character of Shelltown.
