Where do data in the indicator tables of HDR come from?
The Human Development Report Office is primarily a user, not a producer, of statistics. To allow comparisons across countries and over time in the HDR, it relies on international data agencies with the resources and expertise to collect and compile international data on specific statistical indicators. Sources for all data used in the indicator tables are given in short citations at the end of each table. When an agency provides data it has collected from another source, both sources are credited in the table notes. But when an agency has built on the work of many other contributors, only the ultimate source is given. The source notes also show the original data components used in any calculations by the Human Development Report Office to ensure that all calculations can be easily replicated.
