The Freedom in the World political rights and civil liberties ratings are determined through a multi-layered process of research and evaluation by a team of regional analysts and eminent scholars. The analysts used a broad range of sources of information, including foreign and domestic news reports, academic studies, nongovernmental organizations, think tanks, individual professional contacts, and visits to the region, in conducting their research. The methodology of the survey is derived in large measure from the Universal Declaration of Human Rights, and these standards are applied to all countries and territories, irrespective of geographical location, ethnic or religious composition, or level of economic development.
