The vast majority of the country's population (97%) is Muslim, but the constitution does not declare an official religion and all major political forces in the country are secularist. Azerbaijan is a developing country and ranks 88th on the Human Development Index. It has a high rate of economic development, literacy, and a low rate of unemployment. The ruling party, the New Azerbaijan Party, in power since 1993, has been accused of authoritarian leadership and the deterioration of the country's human rights record, including increasing restrictions on civil liberties, particularly on press freedom and political repression.
