Freedom House has ranked North Korea at the very bottom of its "Freedom in the World" ratings since the survey was first launched in 1973. In Freedom House's 2013 survey, North Korea was one of nine countries that earned a 7 (its lowest rating) for both political rights and civil liberties. Its current report on North Korea categorizes it as "Not Free", and states that there are virtually no organizations independent of state control. North Korea has charged that those who make allegations about human rights in the country are interfering with the country's internal affairs and trying to force down their values. Other international NGOs have been established with the purpose of relieving the human rights abuses faced by North Koreans. The North Korea Strategy Center works to provide people living in North Korea with access to videos, music, and other external media that promotes human rights and democracy. An organization called Liberty in North Korea collects charitable donations in order to perform rescue missions for defectors attempting to escape North Korea through China. Still other organizations focus on assisting defectors after they arrive in Southeast Asia, South Korea, the United States, or other destinations. Saejowi, a Seoul-based NGO, aims to provide medical support to defectors in South Korea, because they are often unable to understand the treatment options available to them. With the exception of the international abductions issue regarding Japanese, Americans, and South Koreans, which it says has been fully resolved, North Korea strongly rejects all reports of human rights violations and accuses the defectors of promoting only an anti-North agenda. On September 9, 2020, the Office of the United Nations High Commissioner for Human Rights in Seoul published a report stating that voices of citizens of the Democratic People's Republic of Korea, including women, are being curbed. It urged the United States and South Korea to raise concerns about North Korean human rights abuses, whenever the negotiations with North Korea resumes. Number of victims Estimates based on the North Korean census suggest that 240,000 to 420,000 people died as a result of the North Korean famine and that excess mortality during the whole period 1993 to 2008 was between 600,000 and 850,000. The famine has been described as the result of the economic policies of the North Korean government or as deliberate "terror-starvation".
