Data notes

NGOs are only included if they say they work in fewer than 50 countries. This is because some organisations claim they are working in every single country in the world, or very large numbers of countries. This is unlikely. So we can exclude them by restricting the number of countries organisations work in.

The figures for income and spending include the total income and spending of the organisations in all the countries they work in.

Religious organisations refers to those organisations which self-describe themselves as undertaking "religious activities" in their causes.
