The country is an archipelago with a land area of 288 square miles and a population of 101,000. According to the last published census data from 1996, membership by percentage of population of major religious groups was: Free Wesleyan Church of Tonga, 41 percent; Roman Catholic Church, 16 percent; Church of Jesus Christ of Latter-day Saints (Mormons), 14 percent; Free Church of Tonga, 12 percent; and all other groups, 17 percent. However, both Roman Catholics and Mormons stated that the number of their adherents is higher than reported, and a 2006 survey conducted by the Free Wesleyan Church put its membership at only 35 percent of the population. The Tokaikolo Church (a local offshoot of the Methodist Church), Seventh-day Adventists, Assemblies of God, Anglicans, the Baha'i Faith, Islam, and Hinduism have small numbers of adherents.
1. The Religious Characteristics of States Dataset Project: Government Religious Preference (GRP) measures government-level favoritism toward, and disfavor against, 30 religious denominations. A series of ordered categorical variables index the state's institutional favoritism in 28 different ways. The variables are combined to form five composite indices for five broad components of state-religion: official status, religious education, financial support, regulatory burdens, and freedom of practice. The five components' composites in turn are further combined into a single composite score, the GRP score.

3. The U.S. State Department's International Religious Freedom Report is submitted to Congress annually by the Department of State in compliance with Section 102(b) of the International Religious Freedom Act (IRFA) of 1998. This report supplements the most recent Human Rights Reports by providing additional detailed information with respect to matters involving international religious freedom. It includes individual country chapters on the status of religious freedom worldwide. A dataset with these and the other international measures highlighted on the country pages can be downloaded from this website. These State Department reports are open source.
