== Key findings:[7] (Not adjusted for increase in refusals to reply)== the proportion of the population that can be classified as Christian has declined from 86% in 1990 to 77% in 2001; although the number of adults who classify themselves in non-Christian religious groups has increased from about 5.8 million to about 7.7 million, the proportion of non-Christians has increased only by a very small amount - from 3.3% to about 3.7%; the greatest increase in absolute as well as in percentage terms has been among those adults who do not subscribe to any religious identification; their number has more than doubled from 14.3 million in 1990 to 29.4 million in 2001; their proportion has grown from just 8% of the total in 1990 to over 14% in 2001; there has also been a substantial increase in the number of adults who refused to reply to the question about their religious preference, from about four million or 2% in 1990 to more than eleven million or over 5% in 2001.
