Precision
Never spread state data into fake district values
Map Methodology & Precision
Every analytical map states what is shown, data source and year, unit, aggregation, classification, boundary version, limitations and update date.
Colour must not create false certainty.
Aggregation
Store sum, mean, median, rate or population-weighted method
Classification
Document quantile, equal interval, natural breaks or policy threshold
Confidence
Keep evidence strength separate from severity
No data
Show “No reliable data available”—never “low”
