Studying religion in Indiana reveals a classic Midwestern balance between frontier Protestant revivalism and historic Catholic institutional foundations. Approximately seventy-two percent of adult Hoosiers identify as Christian, led by widespread Methodist and Baptist congregations, historic Stone-Campbell Christian churches, prominent Catholic dioceses, and extensive Old Order Amish farming settlements across northern counties.
Overview of Religion in Indiana: Traditions and Demographics
Demographic surveys conducted by the Pew Research Center and the Association of Religion Data Archives indicate that the Hoosier State maintains one of the most balanced religious populations in the Midwest. Evangelical Protestants represent the largest spiritual segment, comprising thirty-one percent of the adult populace. Roman Catholics constitute eighteen percent, while mainline Protestants account for sixteen percent. Historically Black Protestant denominations comprise roughly five percent of adult citizens, centered primarily in Indianapolis, Gary, and South Bend. Unaffiliated residents make up twenty-six percent of the population, while non-Christian faith traditions, including Judaism, Islam, Hinduism, and Buddhism, represent about two percent of citizens statewide.
The Roman Catholic Church serves as the largest denomination in Indiana by total adherent counts, claiming more than seven hundred and fifty thousand baptized members. Catholics are organized under the Archdiocese of Indianapolis and four suffragan dioceses in Fort Wayne-South Bend, Gary, Lafayette in Indiana, and Evansville. The United Methodist Church stands as the largest Protestant denomination by membership, closely followed by independent Christian Churches and Churches of Christ affiliated with the Restoration Movement. In addition, Indiana serves as the national headquarters for several prominent Christian bodies, including the Christian Church (Disciples of Christ) in Indianapolis, the Church of God in Anderson, and the Wesleyan Church in Fishers.
Directory Statistics: Faith Communities Across Indiana
Congregational figures within our directory catalog illustrate Indiana's broad Protestant distribution and substantial sacramental presence. Out of 1,807 registered houses of worship statewide, Baptist, Methodist, Catholic, and Restorationist assemblies represent more than half of all listed congregations.
Our statewide records document 335 Baptist churches in Indiana, accounting for 18.5 percent of all directory entries. This total includes independent missionary Baptist chapels in rural southern hills, suburban Southern Baptist campuses, and historic African American tabernacles in urban centers. The second largest group is represented by 247 Methodist churches in Indiana, constituting 13.7 percent of listings. Methodism's prominence reflects two centuries of circuit riding that established meeting houses at nearly every rural road junction.
Catholic parishes represent the third largest share, with 218 Catholic churches in Indiana comprising 12.1 percent of listings, serving multi-generational parish communities across both rural German farming settlements and industrial lakefront cities. Demonstrating the state's deep restorationist roots, our records document 199 Christian Churches (11.0 percent), which trace their heritage to the Stone-Campbell Movement. Lutheran congregations account for 191 listings (10.6 percent), followed by 147 Presbyterian and Reformed churches (8.1 percent) and 125 non-denominational evangelical fellowships (6.9 percent). Holiness and Nazarene churches claim 96 listings (5.3 percent), Pentecostal assemblies represent 93 listings (5.1 percent), and Churches of Christ account for 48 listings (2.7 percent), alongside Mennonite, Brethren, and Orthodox assemblies.
Frontier Circuit Riders, Notre Dame, and the Restoration Movement
Indiana's spiritual character was established during the early nineteenth century as pioneers migrated northward across the Ohio River from Kentucky and the Carolinas. Early settlers brought Baptist and Methodist convictions into the southern hardwood forests, planting congregations like Little Pigeon Baptist Church in Spencer County, where a young Abraham Lincoln helped build the meeting house. Methodist circuit riders traveled thousands of miles across muddy forest paths, organizing classes in pioneer log cabins and holding outdoor camp meetings that defined early civic life.
In northern Indiana, Catholic institutional history reached global prominence with the founding of the University of Notre Dame near South Bend in 1842. French priest Father Edward Sorin and his fellow brothers of the Congregation of Holy Cross cleared forested wilderness along Saint Joseph's Lake to construct a Catholic college. Today, the Basilica of the Sacred Heart at Notre Dame, with its soaring neo-Gothic spires, world-renowned French stained glass, and nearby outdoor Grotto of Our Lady of Lourdes, stands as one of the premier centers of Catholic intellectual life and pilgrimage in North America. In southern Indiana, Swiss Benedictine monks founded Saint Meinrad Archabbey in 1854, which remains one of only two archabbeys in the United States, operating a major Catholic theological seminary and school of theology.
Amish Communities, the Holiness Movement, and Sacred Landmarks
In addition to Catholic and mainline foundations, Indiana is home to one of the largest Anabaptist populations in the world. Beginning in the 1840s, Old Order Amish and Mennonite families settled in Elkhart, Lagrange, Adams, and Daviess counties. Around towns like Shipshewana and Middlebury, thousands of Amish families preserve horse-drawn transportation, plain dress, and German-dialect home worship. Their woodworking shops, organic farms, and quiet devotion attract visitors seeking to understand historic Anabaptist nonresistance and simple community living.
During the late nineteenth century, central Indiana became an epicenter of the American Holiness movement. In 1881, evangelist Daniel Sidney Warner founded the Church of God in Anderson, advocating Christian unity, sanctification, and racial harmony. Anderson University developed into the flagship educational institution of this global movement. The state also preserves remarkable sacred architecture. In Vincennes, the Basilica of Saint Francis Xavier, known as the Old Cathedral, was founded in 1732 as the oldest Catholic congregation in Indiana. In downtown Indianapolis, Roberts Park United Methodist Church, completed in 1876 with Romanesque stone arches and walnut galleries, stands as a grand monument of Victorian urban church architecture.

Indiana Compared with Surrounding Regional States
Within the broader framework of religion in the Midwest, the religious landscape of Indiana connects midwestern industrial Catholicism with southern evangelical fervor.
To the west, religion in Illinois exhibits a significantly larger Roman Catholic population dominated by the Archdiocese of Chicago, alongside higher proportions of ethnic immigrant parishes. To the south across the Ohio River, religion in Kentucky is much more heavily Southern Baptist and evangelical, reflecting classic Bible Belt commitments rather than the balanced Midwestern denominational distribution found in Indiana. To the east, religion in Ohio shares comparable Amish communities and mainline Protestant roots, yet Ohio features larger urban industrial Catholic populations in Cleveland and Cincinnati.
