We can but hope

Seems reasonable.

If these trends predictions prove accurate, expect the evangelicals to become much more aggressive and unethical in their actions, as they will feel threatened.

This seems to correlate with reports I’ve heard in the news.

With the numbers that this Cattus has looked at, from Pew Research Center, the US Census, etc and assorted, non-religious affiliation hovering about the 22% mark feels fairly accurate right now.

Agreed with Seeker3CO, the 'straight line'-ness makes it look like there has been a steady surge of non-religious thinking since 1980 and will continue well into next decade at the same rate... I don't know about that.

One thing is for sure, though, with the advent of global social communications and technology, there is more opportunity to dispel mythology to a broader audience; while religiousity flourishes under the same conditions, it also has less place to hide now.

I think it may have already happened. Less than 50% of Americans go to church or temple. How many of those who don't are non-religious but are still being counted by the religions they left?

What is the source of the data, what is the demographic of the data, what data collection method was used, what size sample was used?

To be able to analyse this data efficiently those aspects must be taken into account.

Do you have a link to the original study that produced these results.
