How this is calculated
The compound annual rate between the two cited observations is extended to the source-check year as a model baseline, then 5, 10 or 20 years ahead. Score = 50 + twice that projected percentage change, capped at 0–100; grades start at 65, 45 and 25. This measures population momentum, not jobs, safety or overall quality of life.
A continuation scenario, not an official forecast. The model baseline is an extrapolation, not a new observed population count. Migration, housing supply and policy can change the trend.
Time from the model baseline year to a 20% population reduction if the same rate continues. This is a reference line, not the date a place disappears.
