According to Statistics Canada, Pentecostal growth has varied (statistics Canada does not collect data specific to the PAOC, but as by far the largest Pentecostal group in Canada, it is likely to reflect the statistics regarding Canadian Pentecostals). The 1991 census showed a 29% increase. Between 1991 and 2001, the census reported a 15% decline to 369,480 adherents (Extrapolating the percentage growth indicates approximately 435,000 +/-2,500 adherents in 1991). While self-reported statistics from the PAOC show plateaued growth, the 2011 census indicates 478,705 adherents - a 29% increase over 2001, and 10% increase over 1991 census data. The Evangelical Fellowship of Canada has pointed out that changes to choices available on census forms over the years brings into question the accuracy and usefulness of Statistics Canada data on evangelical denominations, so it is likely PAOC data is a more accurate measure. The PAOC had "fewer than 225,000 members and adherents as of 1994," which compared with the 2014 data of 239,267 indicates growth of just 6% in the 20-year period.. How many more percent had the population of the PAOC grown from 1991 to 20i1 than it did from 1991 to 2001?
