The global Muslim population reached a historic milestone of 2.06 billion in 2026, representing over 25% of the world's total population of about 8.25 billion, according to the latest demographic reports. This means every 1 in 4 people on Earth is now Muslim. Islam remains the world's fastest-growing major religion, growing at 1.84% annually and outpacing global population growth and other faiths. According to 2026 data, Indonesia remains the world's largest Muslim country with 242.7 million Muslims, followed by Pakistan and India. The growth is driven by sustained population momentum, particularly in countries like Nigeria, Indonesia, and Pakistan, where young populations and above-replacement fertility rates contribute to rapid growth. Regional highlights: • South Asia & Sub-Saharan Africa are the fastest-growing regions • Asia-Pacific is the largest Muslim-majority region • Russia is seeing a surge among ethnic Russians in Moscow and St. Petersburg, attracted to Islam's strong family values • Experts predict that by 2050, up to one-third of the Russian population will be Muslim and the global Muslim population may hit 3 billion by 2060 Pew Research Center projects that Muslims have expanded by 347 million over the past decade, while Christians remain the largest at 2.3 billion, but their share is edging down. Singapore has been named the world's most religiously diverse country. This demographic shift is driving growth in Islamic finance ($6 trillion market), Halal tourism (Malaysia retaining No.1 spot for 11th year), and Halal food industries globally.
