We defined the “most disadvantaged” in each country to be anyone that is below a given threshold.
Based on an analysis of 54 countries from different regions, the graphs above show the distribution of the number of quintiles “deprived” from Early Childhood Opportunities. In this particular case the threshold has been defined as being at least 1 standard deviation below the mean of the wealthiest quintile (N.B.: this functionality is currently being incorporated into EQUIST). The analysis of the number of quintiles below one standard deviation of Early Childhood DALYs from the richest quintile helps to identify in a more refined way the three different typologies (as described in 2010 Study on Narrowing the Gap namely:
Type A countries: where the richest quintile largely differs from the four poorest quintiles by DALYs comparatively less than 1 SD. This is the most common pattern in the Sahelian countries and the Horn of Africa.
Type B countries: where there is a difference mainly between the two richest quintiles and the three poorest ones. This is the most common pattern in South Asia and the coastal countries in Africa (except the “Horn of Africa)
Type C Countries, where children in the two poorest quintiles are worse off than children in the three richest quintiles. This is the most common pattern in high and middle-income countries in the Middle East, Central Asia, Latin America and the Caribbean.
