Among the countries with freedom of religion protected both on paper and in daily life, a familiar set of names comes up repeatedly: the United States, Canada, Australia, Germany, South Korea, Taiwan, New Zealand, Japan, and the United Kingdom. What links them is not a shared structure but a shared outcome. Some maintain strict separation between church and state, others keep an established church, and a few take a hands-off approach that barely regulates religious life at all. All of them combine legal guarantees with independent courts and a social climate that tolerates difference.
Around 80 countries include explicit religious freedom protections in their constitutions, and more than 170 are parties to the International Covenant on Civil and Political Rights, whose Article 18 bars coercion in matters of belief.1Office of the United Nations High Commissioner for Human Rights. International Covenant on Civil and Political Rights The gap between that legal universe and lived reality is wide, which is why comparing countries requires more than reading constitutions.
How Religious Freedom Is Measured Across Countries
Two tools do most of the comparative work. The Pew Research Center publishes a Government Restrictions Index and a Social Hostilities Index covering 198 countries and territories. The first uses 20 indicators to score how national and local governments restrict religion, including laws limiting conversion, registration burdens, and outright bans on certain faiths. The second uses 13 indicators to measure private hostility, from religiously motivated violence to organized efforts to shut certain groups out.2Pew Research Center. Restrictions Methodology A country can score well on one and badly on the other. The countries that genuinely protect religious freedom score low on both.
The U.S. Commission on International Religious Freedom takes the opposite tack, spotlighting the worst offenders rather than ranking every state. In its 2025 Annual Report, USCIRF recommended 16 countries for designation as “Countries of Particular Concern”: Afghanistan, Burma, China, Cuba, Eritrea, India, Iran, Nicaragua, Nigeria, North Korea, Pakistan, Russia, Saudi Arabia, Tajikistan, Turkmenistan, and Vietnam.3United States Commission on International Religious Freedom. 2025 USCIRF Annual Report
Countries With the Strongest Legal Protections
The strongest constitutional frameworks share two features. They keep the government from favoring one religion over another, and they protect the individual’s right to practice freely. Several countries stand out.
United States
The First Amendment contains two distinct protections. It bars Congress from establishing a religion and separately prohibits the government from restricting the free exercise of religion.4Congress.gov. U.S. Constitution – First Amendment The government can neither promote a particular faith nor penalize people for practicing theirs. Court challenges under these clauses typically turn on whether a government action places a substantial burden on someone’s sincerely held religious beliefs.
Canada
Section 2 of the Canadian Charter of Rights and Freedoms lists freedom of conscience and religion as a fundamental freedom belonging to everyone.5Department of Justice Canada. Charterpedia – Section 2(a) – Freedom of Religion Canadian courts read this broadly, covering the right to hold any religious belief, to declare it openly without fear of reprisal, and to practice it through worship and teaching. The Charter is the main vehicle citizens use to challenge government interference with religious expression.
Australia
Section 116 of the Australian Constitution imposes four prohibitions on the Commonwealth: no law establishing a religion, none imposing a religious observance, none prohibiting the free exercise of any religion, and no religious test for any office or public trust.6Attorney-General’s Department (Australia). Right to Freedom of Thought, Conscience and Religion or Belief That last prohibition matters. A person’s faith, or lack of one, cannot disqualify them from public office.
Germany
Article 4 of Germany’s Basic Law declares freedom of faith, conscience, and religious creed inviolable and guarantees the undisturbed practice of religion.7Federal Ministry of Justice (Germany). Basic Law for the Federal Republic of Germany Germany runs a cooperative model in which the state and religious communities work together on things like religious education in public schools and a church tax collected on behalf of registered denominations. It is not strict separation, but the arrangement extends to all qualifying religious groups rather than privileging one faith.
South Korea
Article 20 of the South Korean Constitution states plainly that all citizens enjoy freedom of religion, that no state religion shall be recognized, and that religion and state shall be separated.8Korea Legislation Research Institute. Constitution of the Republic of Korea Buddhism, Christianity, and various newer movements all operate freely, and the country consistently scores among the lower-restriction nations on international indexes.
Taiwan and New Zealand
Taiwan’s constitution guarantees freedom of religious belief, and the government supports a diverse religious landscape without heavy regulation of minority groups. New Zealand’s Bill of Rights Act 1990 protects freedom of thought, conscience, religion, and belief, including the right to adopt and hold opinions without interference.9New Zealand Legal Information Institute. New Zealand Bill of Rights Act 1990 – Section 13 Both regularly appear near the top of religious freedom rankings.
Different Structures That All Work
One of the more counterintuitive findings in comparative religious freedom is that very different structures produce similar outcomes. There is no single correct model.
Strict Separation in France
France follows laïcité, rooted in a 1905 law that separated churches from the state. The government does not officially acknowledge, fund, or subsidize any form of worship. The tradeoff surfaces in public schools, where a 2004 law prohibits students from wearing conspicuous religious symbols, including headscarves, large crosses, and yarmulkes. Supporters call it neutrality; critics call it a restriction on personal expression. The debate continues over where the line falls.
Established Church in the United Kingdom
The UK takes the opposite structural approach. The Church of England holds official status, the monarch heads it, and senior bishops sit in the House of Lords. Despite that formal establishment, comprehensive protections cover all faiths and people of no faith. The Human Rights Act 1998 brought Article 9 of the European Convention on Human Rights into domestic law, guaranteeing freedom of thought, conscience, and religion for everyone.10Legislation.gov.uk. Human Rights Act 1998 – Schedule 1 Part I Chapter 8 The established church’s legal effects are largely ceremonial, and the UK scores well on religious freedom measures.
Minimal Interference in Japan
Japan produces some of the world’s lowest government restriction scores through a hands-off approach. Religious groups do not need to register with the government to practice. Registration as a “religious juridical person” is optional and exists mainly to give an organization legal personality and tax benefits.11Agency for Cultural Affairs (Japan). Religious Juridical Persons and Administration of Religious Affairs Japan’s Religious Corporations Act states expressly that its provisions must not be construed as restricting any individual or group from disseminating teachings, conducting ceremonies, or carrying out other religious activities.12Japanese Law Translation. Religious Corporations Act Hundreds of thousands of religious organizations operate with minimal state oversight.
Nordic Transitions
Several Nordic countries maintained official state churches for centuries but have gradually moved toward treating all religious and non-religious groups more equally. Sweden formally separated church and state in 2000; Norway completed a similar transition in 2017. Where ties have loosened rather than fully severed, the practical effect on individual liberty has been minimal. Government restrictions stay low, and social hostility toward religious minorities remains below global averages.
Countries That Restrict Religious Freedom the Most
USCIRF’s 2025 list points to the worst cases. North Korea effectively bans all independent religious practice. China maintains an extensive system of state control over recognized religions and has been documented subjecting Uyghur Muslims and Tibetan Buddhists to mass detention and surveillance. Iran enforces religious law as state law and prosecutes members of minority faiths, particularly Baha’is. Saudi Arabia prohibits public practice of any religion other than Islam. Russia has used its “anti-extremism” laws against groups like Jehovah’s Witnesses, effectively criminalizing their worship.3United States Commission on International Religious Freedom. 2025 USCIRF Annual Report
India’s presence on the USCIRF list is notable given that the Indian constitution protects religious freedom. The commission’s concern is enforcement: state-level laws restricting conversion, demolitions of minority religious structures, and rising social hostility toward Muslims and Christians in several states. Constitutional text alone does not guarantee religious freedom in practice.
Blasphemy Laws as a Warning Sign
One of the clearest signals that a country limits religious freedom is a blasphemy law. According to USCIRF, at least 84 countries maintain some form of blasphemy provision, covering more than a third of the world’s nations.13United States Commission on International Religious Freedom. Legislation Factsheet – Blasphemy These laws criminalize speech or actions deemed offensive to a religion, and they disproportionately harm minorities and dissenters. They make the state the arbiter of religious truth, and in some countries blasphemy accusations have triggered mob violence and extrajudicial killings.
The trend among free democracies runs the other way. Malta repealed its blasphemy law in 2016, Denmark in 2017, and Canada, New Zealand, Greece, and Ireland all repealed theirs in 2018 or 2019.13United States Commission on International Religious Freedom. Legislation Factsheet – Blasphemy Each repeal recognized the same problem: a country cannot protect religious freedom while criminalizing speech about religion.
Why Constitutional Text Is Not Enough
The most important lesson from any survey of religious freedom is that legal text and lived reality often diverge. Countries with sterling protections sometimes fail to enforce them. Countries with an established church sometimes produce better outcomes for minorities than countries with strict separation on paper.
What sets apart the countries that actually protect religious freedom is a combination of legal infrastructure, an independent judiciary willing to enforce it, and a social culture that tolerates difference. Japan does not aggressively regulate religion, and its population does not aggressively persecute minorities. Canada has strong legal protections, and its courts hold the government accountable when it oversteps. The UK manages an established church alongside robust protections for every other faith.
For a closer look at any specific country, the Pew Research Center’s two indexes give the most granular data, covering 198 countries with scores updated regularly.2Pew Research Center. Restrictions Methodology The USCIRF annual reports focus on the worst offenders and include specific recommendations for U.S. policy.3United States Commission on International Religious Freedom. 2025 USCIRF Annual Report Together they offer a far more reliable picture than any single constitution can.
