Politics of the Marshall Islands takes place in a framework of a parliamentary representative democratic republic, and of an emerging multi-party system, whereby the President of the Marshall Islands is both head of state and head of government. Executive power is exercised by the government. Legislative power is vested in both the government and the Nitijela (Legislature). The Judiciary is independent of the executive and the legislature.
The people of the Marshall Islands face considerable challenges to maintain the health of its citizens. Recently, high population growth and crowded conditions in urban areas, have given rise to diseases, such as tuberculosis and leprosy. These conditions typically come about in rapid growth areas of the world that have limited economic and medical resources. In addition, exposure to the influence of Western culture has brought about a rise in the levels of adult obesity, non-communicable diseases, teenage pregnancy, suicide, and alcoholism, and tobacco use.
In traditional Marshallese society, the youth learned essential skills, concepts, and attitudes through direct involvement with family and community. Persons with special knowledge or skills trained selected apprentices to preserve the skills and cultural knowledge. In 1857, the Boston Missionary Society arrived to establish church schools on 22 atolls. The missionary schools continued to exist through German and Japanese occupations of the islands until shortly before World War II.
