The median income in Fredericksburg has fluctuated over the past decade. It increased from $54,576 in 2013 to a peak of $70,611 in 2021, before decreasing to $59,672 in 2022. The population has grown overall, from 660 in 2013 to 850 in 2022, with some variations in between. The economic trends do not appear to strongly correlate with the minor demographic shifts observed.

Fredericksburg's lack of diversity contrasts with national trends towards increasing diversity in many areas of the United States. The median income of $59,672 in 2022 is close to the national median household income, which was approximately $70,784 in 2021. The community's resistance to diversification over the decade, despite some economic growth and population increase, suggests it may be a relatively isolated or rural area with limited in-migration from diverse populations.

In conclusion, Fredericksburg has experienced economic fluctuations and population growth over the past decade, but its racial composition has remained stable, maintaining its status as a "Low Diversity" community. The brief appearance of a small Hispanic population and the recent emergence of a multi-racial category suggest potential future changes, but as of 2022, these shifts have not significantly altered the community's demographic profile.
