The institutional coverage of the figures for that country corresponds to the budgetary central government. Since it is a federal country, the published figures may have underestimated total social spending to a greater extent than in other countries reporting that coverage. The same is true of Mexico: the available information on the highly-decentralized execution of its spending show that the figures should be studied more carefully than in other cases because the underestimation of social spending levels may be quite considerable. The indicators shown are for overall public social spending and spending by function or sector—education, health, social security and welfare, and housing, sanitation and other functions not included in the previous categories— as percentages of GDP, in dollars per capita and as percentages of total public spending. These proportions are then applied to the GDP series in dollars at 2000 prices so that per capita social spending, expressed in dollars, can be derived.
