Before revision:  By contrast, average increases in HAZ above a country's starting point, which we define as accrued HAZ , show strong correlations with these same variables, suggesting that low accrued HAZ captures standard definitions of stunting as impaired growth due to undernutrition. Using these two components, we show how universal cutoffs can underestimate stunting in specific world regions (e.g., sub-Saharan Africa and the Caribbean), where children in even very deprived situations start off taller .

Population-sensitive estimates suggest that universal cutoffs can underestimate stunting in specific world regions (e.g., sub-Saharan Africa and the Caribbean), where children in even very deprived situations start off taller .
