C - Above AverageWhat drives the Adams County index
The FDR Index combines five measured parts into one 0 to 100 score. Each part is scored 0–100 against all Illinois counties.
Buck Index
90→ out of 100. How this county ranks on the Buck Index against every county we cover. 100 is the top. Land is measured as what a hunter can actually hunt (10 m estimate).
Hunting pressure
Pressure Index 4.7 / 10 (Middle). About 5.3 deer hunters per square mile of huntable land: 47th percentile of 3,051 rated counties in 48 states, 63rd percentile within Illinois. How often deer run into people, 0 to 10 on one scale across every rated state; 10 is the most crowded county in the country.
Modeled. Illinois does not publish hunter numbers by county, so FDR places this county within Illinois from deer harvest per huntable acre (2020 to 2024 seasons) and population density. The model was checked against agency hunter counts in Michigan, Indiana and Missouri, and against agency hunter surveys by hunting unit in 10 more states. It estimates crowding; it is not a hunter count. Illinois averages 5.2 deer hunters per square mile of huntable land (state wildlife agency count, 2023-24 season).
