Using anchored rank distribution to benchmark country leveland performance on child-related SGDs

Anchored rank percentiles allow us to benchmark a country’s performance by anchoring or fixing specific reference values and then identifying the percentile or average percentiles where a country or specific countries rank. This method provides a relative sense of how far each country is from the best-performing one measured in the group – e.g., income group, region – while retaining an absolute reference by anchoring the percentiles in historical data.
