In a typical church, only 10% of the first time visitors start attending.
It takes 338 visitors to grow by 50 people per year in average attendance.
If people are contacted within 36 hours of their visit, there is an 85% chance they will return. If they are contacted within 72 hours, there is a 60% chance they will return.
Regular attendance does not mean ownership—the number one time that people leave churches is one year after they start attending.
People stay primarily because they make connections with other people, get involved, and/or are touched by the Spirit of God.
Seekers are seeking relationships with people often as much as they are seeking God—70% of adult Americans have many acquaintances but few close friends.
