Religious Affiliation of Indian Americans 
Not all Indian Americans are Hindu. Only about half (51%) of Indian Americans are Hindu, though nearly all Asian-American Hindus (93%) trace their heritage to India, according to our 2012 survey. 18% of Indian Americans identified themselves as Christians (as both Haley and Jindal do); 10% said they were Muslim. The religious shares of Indian Americans are markedly different from those of India itself (where an estimated 79.5% of the population is Hindu and only 2.5% is Christian, according to Pew Research’s 2012 Global Religious Landscape report), reflecting differential migration patterns.
