Big Rock has maintained its "Low Diversity" status over the past decade. From 2013 to 2020, the white population consistently exceeded 95%. Recent years have shown slight shifts towards increased diversity. In 2021, the white population decreased to 87%, while the Black population rose to 7%.

The median income in Big Rock has fluctuated over the past decade. From 2013 to 2019, it ranged between approximately $56,000 and $71,000. A significant upward trend began in 2020, with the median income rising to $80,127, peaking at $95,640 in 2021, before slightly decreasing to $80,188 in 2022.
The brief increase in diversity in 2021 coincided with the peak in median income. This could suggest that the temporary influx of a more diverse population might have been related to economic opportunities or changes in the local job market.
Population trends show a general decline from 552 in 2010 to 431 in 2019, followed by a slight increase to 473 in 2022. This recent population growth aligns with the increase in median income, possibly indicating improved economic conditions attracting new residents.
Big Rock's racial composition is significantly less diverse than the national average. The U.S. Census Bureau reported that the white alone, not Hispanic or Latino, population was about 59% nationally in 2022, compared to 93% in Big Rock.
The median household income in Big Rock ($80,188 in 2022) is higher than the national median, which was around $70,784 in 2021. This suggests that despite its small size and lack of diversity, Big Rock is relatively affluent compared to national averages.
The community's resistance to significant demographic changes, despite economic fluctuations, might indicate strong local cultural or economic factors that maintain the current population composition. The brief shift in 2021 suggests that the community is not entirely immune to demographic changes. Future years may reveal whether this was an isolated incident or the beginning of a longer-term trend towards increased diversity.
