In addition to maintaining peace, the UN aims to protect human rights and provide humanitarian assistance when needed. In 1948, the General Assembly adopted the Universal Declaration of Human Rights as a standard for its human rights operations. The UN currently provides technical assistance in elections, helps to improve judicial structures and draft constitutions, trains human rights officials, and provides food, drinking water, shelter, and other humanitarian services to peoples displaced by famine, war, and natural disaster.
Finally, the UN plays an integral part in social and economic development through its UN Development Program. This is the largest source of technical grant assistance in the world. In addition, the World Health Organization, UNAIDS, The Global Fund to Fight AIDS, Tuberculosis, and Malaria, the UN Population Fund, and the World Bank Group to name a few play an essential role in this aspect of the UN as well. The UN also annually publishes the Human Development Index to rank countries in terms of poverty, literacy, education, and life
