The US population is now over 300 million. so according to Barna's numbers, there are
over 100 million pentecostals/charismatics in America. To me, these numbers are questionable, to say the least.
Many times, these types of numbers represent the total number of people who are
members of churches that are "pentecostal/charismatic/"full gospel" . But many of the people in these churches and denominations have not personally received the baptism of the Holy Ghost.
For example, as has been noted on this forum previously, only about 20% of Assemblies of God new-converts are now receiving the baptism of the Holy Ghost (

Acts 2:38 salvation.
