Note on coverage rates
Population data from the UN Population Division, alongside recipient numbers, is used to calculate the percentage of the population aged 60 and over covered. Coverage rates of above 100 per cent are either the result of innacuracies in population data or reflect pensions being recieved by those aged under 60.
Note on the poverty line
The International Poverty Line is set at PPP$1.25 a day according to the latest estimations from the World Bank.
