Fairfax County could soon see a spike in the population of senior residents. New demographic data from the county estimates that the population of those age 65 and older is expected to grow by almost 68%, from 190,000 in 2025 to 320,000 by 2045, FFXNow first reported.
This is a significant surge in comparison to the overall county population growth. In that same time frame, the county’s complete population is expected to grow about 12%, from 1.2 million to 1.34 million.
By 2045, seniors age 65 and up are expected to account for 23.9% of all Fairfax County residents. Those age 55 and up will account for 35.1% of the county.
Median Household Income Nearly Double National Median
In addition to the growing senior population, the 2025 report highlighted other aspects of how the county has changed.
Between January 2024 and January 2025, the Fairfax County population increased 0.3% to 1,199,660. The median value of owned housing increased by 6.2% to $752,378.
And, according to the Census Bureau’s 2024 American Community Survey, the median household income was $154,545, an increase of 9.2% from 2023. That’s nearly double the national median of $81,604 and 1.5 times the state median of $92,090.
The report also uses a metric called the Gini index to track income inequality. It ranges from 0, indicating perfect equality, to 1, indicating inequality. In 2024, Fairfax County’s Gini index declined slightly from 0.43 to 0.42, indicating less income inequality.
