United Nations Development Program
An incredible set of demographic data put together by the United Nations. Their mission statement:
Human Development Reports (HDRs) have been released most years since 1990 and have explored different themes through the human development approach. They have had an extensive influence on development debate worldwide. The reports, produced by the Human Development Report Office for the United Nations Development Programme (UNDP), are ensured of editorial independence by the United Nation's General Assembly. Indeed they are seen as reports to UNDP, not of UNDP. This allows each report greater freedom to explore ideas and constructively challenge policies. The reports have also inspired national and regional analyses which, by their nature, usually address issues that are more country – or regionally - specific.
