This forum is not representative of the general population. For one thing it is comprised of as many atheists and agnostics as believers, and that is not representative of the population at large.
People are only becoming less religious in certain countries like the United States, Canada, and northern Europe mostly because they are leaving Christianity, but religion is on the rise globally, and statistics show that.
Since the year 2000, religion has made resurgence whereas atheism and agnosticism are on the decline.
The growth rates of the Abrahamic religions from 1910-2010 were as follows: Judaism .11%, Christianity 1.32%, Islam 1.97%, and Baha’i Faith 3.54%.
Atheism was growing at a rate of 6.54% from 1910-2010 but dropped to a growth rate of 0.05% from 2000-2010. Agnosticism was growing at a rate of 5.45% from 1910-2010 but dropped to a growth rate of 0.32% from 2000-2010. That demonstrates that both atheism and agnosticism are on the decline but also that there are many more agnostics than atheists.

Christianity is growing in certain countries like China so Christians falsely believe that Christianity is going to make a resurgence, but that is not what statistics show worldwide. Islam is projected to overtake Christianity by the middle of this century. Moreover, people in many countries are leaving Christianity in droves, and that accounts for most atheists, except the few atheists who were born into an atheist family, and that is much more common in Europe than the U.S.
Atheism growing? No, atheism is actually on the decline!

Atheism is not growing despite what atheists may say. Real surveys and statistics say atheism is on the decline worldwide. Sorry atheists but atheism is not on the rise nor is it winning. It's still the minority and a declining one at that.
The Pew Research Center's statistics show that atheism is expected to continue to decline all the way into 2050 with a continued growth of religion. Other research also shows a huge surge in growth for Christianity in China which is currently the world's most "atheist" nation because of the atheist communist government suppressing religion, the research suggests that China will soon become the world's most Christian nation within 15 years.
This is simply history repeating itself: Christianity prospered in Rome back in the ancient era when it was suppressed and it still grew in the militant atheist soviet Russia when it was suppressed there only a century ago with the majority of Russians today now also identifying as Christian. Just goes to show that atheist suppression of religion still doesn't stop religion.
