Islam vs Judaism

Islam is the world's second-largest and fastest-growing major religion, with approximately 1.9 to 2.0 billion adherents. Muslims constitute majorities in approximately 50 countries across the Middle East, North Africa, Central Asia, South Asia, and Southeast Asia. [1][4]

The largest Muslim-majority country by population is Indonesia (approximately 230 million Muslims), followed by Pakistan, Bangladesh, and Egypt. India, while Hindu-majority, has one of the world's largest Muslim populations (approximately 200 million). Significant Muslim communities also exist in China, Russia, Europe, and North America. [1][4]

Sunni Muslims constitute approximately 85-90% of the global Muslim population, while Shia Muslims represent roughly 10-15%, concentrated primarily in Iran, Iraq, Bahrain, Azerbaijan, and parts of Lebanon. Ibadi Muslims, found mainly in Oman, represent a smaller distinct tradition. [1][4][2][3]

Islam is projected to grow significantly in the coming decades due to higher fertility rates and a younger demographic profile compared to other major religions. Some projections suggest that Islam could approach Christianity in total adherent count by mid-century. Muslim communities in Europe and North America have grown substantially through immigration and conversion. [1][4]

The global Jewish population is estimated at approximately 14 to 15 million, making Judaism one of the smaller major world religions by adherent count but one of the most historically influential. [1][4]

Israel has the largest Jewish population (approximately 6.9 million), followed by the United States (approximately 5.7-7.5 million, depending on the definition used). Significant Jewish communities also exist in France (approximately 450,000), Canada (approximately 390,000), the United Kingdom (approximately 290,000), Argentina (approximately 180,000), Russia, Australia, and Germany. [1][4]

The Holocaust (1941-1945) resulted in the murder of approximately six million Jews, roughly one-third of the world's Jewish population at the time, and devastated Jewish communities across Europe. The establishment of the State of Israel in 1948 created a new center of Jewish life and has been a defining event in modern Jewish history. [2][3]

Within Judaism, denominational affiliation varies by country. In the United States, the largest movements are Reform (approximately 35% of affiliated Jews), Conservative (approximately 18%), and Orthodox (approximately 10%), with many Jews unaffiliated or identifying as "just Jewish". In Israel, the religious landscape is divided between secular, traditional, religious (dati), and ultra-Orthodox (haredi) categories. [2][3][1][4]
