Outreach 100 is a collaborative initiative from Outreach Magazine, LifeWay Research, and Exponential that seeks to identify America's fastest-growing and largest churches. Each year, it compiles detailed rankings and analyses based on participation from over 13,000 evangelical Protestant churches, focusing on their in-person attendance averages. The initiative provides valuable insights into successful church practices, featuring profiles of thriving congregations and interviews with their pastors, helping other churches learn and adapt effective strategies for growth.

Beyond simply celebrating church attendance numbers, Outreach 100 emphasizes the transformative impact these congregations have on their communities, showcasing the individuals behind the statistics who have found hope through faith. The resource serves as both a directory of statistical data and a source of inspiration, filled with outreach ideas, innovations, and leadership resources designed to equip churches in advancing their mission. For anyone interested in the dynamics of church growth and community outreach, Outreach 100 offers a wealth of information and insights into the contemporary church landscape.
