Theres a constant stream of new evidence to reinforce the long-term trend of religious affiliation falling and nonbelief rising. One such is this June 2019 poll from the Wall Street Journal:
The steady, long-term decline in church attendance is confirmed in the most recent Wall Street Journal/NBC News poll. Just 29% of Americans now say they attend religious services once a week or more often. That is down from 41% in 2000.
At the same time, the share of Americans saying they never attend religious services has risen to 26%, almost double the 14% who said so back in 2000. The rise in churchlessness is most dramatic among young Americans. Among those aged 18 to 34, the rate saying they never attend religious services previously was no different from the national rate; now the share of these younger Americans who never attend religious services has more than doubled, to 36%.
You can see this societal sea change playing out in a new Gallup poll which finds that Americans confidence in organized religion has sunk to 36%, an all-time low:
Confidence in organized religion topped confidence in all other institutions from 1973 to 1985, and, even after falling amid televangelist scandals in the 1980s, it registered at the majority level consistently until 2001. After the Boston Globes 2002 expose revealed Catholic church leaders were aware of and did not take strong action to stop serial sex abuse by priests, confidence in organized religion dropped sharply to 45%. It recovered slightly in the years after the scandal broke, hovering around the 50% mark. Between 2010 and 2017, it regularly registered in the 40s. Since then, in 2018 and 2019, Americans confidence in religion has been below the 40% mark.
