Population
This entry gives an estimate from the US Bureau of the Census based on statistics from population censuses, vital statistics registration systems, or sample surveys pertaining to the recent past and on assumptions about future trends. The total population presents one overall measure of the potential impact of the country on the world and within its region. Note: Starting with the 1993 Factbook, demographic estimates for some countries (mostly African) have explicitly taken into account the effects of the growing impact of the HIV/AIDS epidemic. These countries are currently: The Bahamas, Benin, Botswana, Brazil, Burkina Faso, Burma, Burundi, Cambodia, Cameroon, Central African Republic, Democratic Republic of the Congo, Republic of the Congo, Cote d'Ivoire, Ethiopia, Gabon, Ghana, Guyana, Haiti, Honduras, Kenya, Lesotho, Malawi, Mozambique, Namibia, Nigeria, Rwanda, South Africa, Swaziland, Tanzania, Thailand, Togo, Uganda, Zambia, and Zimbabwe.

note: because of the island's limited economic and educational opportunities, Niueans have emigrated for decades - primarily to New Zealand, but also to Australia and other Pacific island states; Niue's population peaked in 1966 at 5,194, but by 2005 had fallen to 1,508; since then it has rebounded slightly; as of 2013, 23,883 people of Niuean ancestry lived in New Zealand - with more than 20% Niue-born; this means that there are about 15 times as many persons of Niuean ancestry living in New Zealand as in Niue, possibly the most eccentric population distribution in the worldNorfolk Island
