Ethiopia
Ethiopia's population has grown from 33.5 million in 1983 to 87.9 million in 2014. The population was only about 9 million in the 19th century. The 2007 Population and Housing Census results show that the population of Ethiopia grew at an average annual rate of 2.6% between 1994 and 2007, down from 2.8% during the period 1983–1994. Currently, the population growth rate is among the top ten countries in the world. The population is forecast to grow to over 210 million by 2060, which would be an increase from 2011 estimates by a factor of about 2.5.
P'ent'ay
According to the 2005 statistics from the World Christian Database, Ethiopian Pentecostal/Charismatic members cover a bit over 16 percent of the country as P'ent'ays of Ethiopia. The individual groups are the Word of Life Church (Qale Hiywet) church, Mekane Yesus, Churches of Christ, Misgana Church of Ethiopia, Assembly of God, Hiwot Berhan Church, Emnet Kristos, Meserete Kristos, Light of Life Church, Mulu Wongel (Full Gospel Believers Church) and other churches constituting slightly over 12 million P'ent'ays in Ethiopia. However, according to World Christian Encyclopedia, the Evangelical community is down to only 13.6% of Ethiopian population. According to the 1994 government census, Protestant Christians comprise 10% of the population (about 7-8 million today). According to membership and adherent records provided by the various churches and denominations, Ethiopian Protestants claim as high as 18.59% of the country's population which is inline with the recent data from the US department of state.
