gentrification index
Standardizes current-minus-baseline change by a supplied scale, applies an explicit direction and weight, clips extreme components, and maps the weighted result to a 0–100 descriptive index. Metric selection and interpretation remain with the caller. It does not obtain data, identify individuals, establish causation, rank residents or justify displacement decisions.
