A more reasonable indicator of this commitment would be the proportion of public spending or public revenues that is allocated to social protection since this would (to an extent) neutralise the fact that public revenues as a proportion of GDP differ widely even among countries at the same income level. Looking at spending in absolute terms also demonstrates that per capita spending can increase substantially in a fast-growing economy even when expenditure is declining relative to GDP or public expenditure. However, this is not an ideal basis for long-term projections, especially in a context where the future plans of development partners are not clear and expenditure by new programmes, such as CBHI, is difficult to predict.
