Despite overall population decrease, the neighborhood maintains a high density, characteristic of urban areas in historic cities like Savannah. This density could be attributed to the neighborhood's location and city efforts to preserve historic charm while accommodating modern urban living.

Population fluctuations may be influenced by changes in housing availability, economic conditions, or shifts in demographic preferences. The drop from 857 residents in 2015 to 574 in 2020 could relate to broader urban trends or specific local events affecting housing and population distribution in Savannah.

Sackville's location in Savannah, known for historic districts and tourism, may influence these population dynamics. The neighborhood could experience pressures from tourism-related development or gentrification, often leading to changes in residential patterns in historic urban areas.

The estimated 239 housing units for the 2022 population, based on the national average household size, suggests a compact living environment. This setup likely promotes a lifestyle balancing urban convenience with historic charm, possibly attracting a mix of long-term residents and newcomers.

In conclusion, while Sackville has seen a general population decline in recent years, it remains a densely populated urban neighborhood. This density, combined with Savannah's historical significance, likely creates a distinctive living experience blending urban amenities with historical ambiance, despite challenges indicated by population trends.
