This growth represents an 8.4% change from the previous population count of 6,020 people.

Each year, about 15.6 people moved to the area for each dwelling built during these years. This high demand relative to supply typically drives price growth and increased buyer competition. New homes are constructed at an average cost of $626,000, indicating a focus on premium market properties.
