New membership in the NAD comes mainly from the African descent demographic. This group makes up approximately 30 percent of the NAD membership compared to its 12.8 percent share of the population. Though we rejoice in the diversity of the church, this figure shows that NAD is not effectively reaching the Caucasian descent group. They make up 55 percent of the NAD church relative to a 67 percent population in 2005.
