Income group tables For operational and analytical purposes the World Bank’s main criterion for classifying economies is gross national income (GNI) per capita . Each economy in The Little Data Book is classified as low income, lower middle income, upper middle income, or high income . Note: Classifications are fixed during the World Bank’s fiscal year (ending on June 30), thus countries remain in the categories in which they are classified irrespective of any revisions to their per capita income data . Low-income economies are those with a GNI per capita of $1,045 or less in 2014 . Lower middle-income economies are those with a GNI per capita of more than $1,046 but less than $4,125 . Upper middle-income economics are those with a GNI per capita of more than $4,126 but less than $12,735 . High-income economies are those with a GNI per capita of $12,736 or more .
