According to a new Pew Research Center poll, non-religious people now make up about 20 percent of the US population and are rapidly expanding in numbers. A third of these people are under the age of thirty. In fact, the poll shows that the younger the people polled, the less religious they are. For example, 90 percent of those over the age of 65 are religious while only 67 percent of those aged 18-29 are religious. These non-religious people are more than twice as likely to identify as ‘liberal’ than ‘conservative.’ It’s also interesting to note that since 1972 the percentage of Catholics in the US population has nearly stayed the same, slipping just slightly from 26 to 25 percent (despite massive immigration from mostly-Catholic Latin America). Meanwhile, the percentage of the population that is Protestant has fallen rather dramatically from 62 to 51 percent. As well, the percentage of non-religious people has risen greatly from 7 to 18 percent. The poll reveals lots of fascinating information about the long-term trends going on in the United States and is worth studying for a glimpse of what the future holds.
