$100,000 has a household-income percentile estimate of 55.9 in Gwinnett County, GA under the 2020-2024 ACS grouped distribution. Without assuming where households fall inside the published income group, the supported rank interval is 55.9 to 66.9.
The result is a deterministic estimate from the published ACS county household counts in 16 income groups. Linear interpolation is used only inside a closed published group; the complete published-group percentile interval is always disclosed. ACS B19001 does not subdivide household incomes of $200,000 or more. Values in that open-ended group receive a percentile floor and top-share ceiling, never a fabricated point percentile.
