Past and present
In intolerant societies, atheists have been persecuted throughout history, and at times, there were very few atheists. Today there is still extreme intolerance or persecution in some places; examples are the Bible Belt in the United States and fundamentalist islamic countries.
In advanced countries with modern education, atheism is becoming more popular fast, and people who’ve learned the scientific method see that there is no reason to believe in a religion.
- Some European countries, such as Sweden, may have a majority population of atheists or agnostics.
- In the United Kingdom, it appears that around 1 in 5 people are atheist or agnostic.
- In the United States, 0.5% of people are strong atheists according to some surveys, while 30 million Americans are atheists according to American Atheists. 
Surveys are unreliable, as answers depend upon how questions are phrased. This article needs more citations.
Why is atheism increasing?
- Most Christians have religious doubts. Some Christians struggle with doubt, and more sensible people see that doubt is reasonable, and become former Christians.
Doubt comes from the Devil!Young children, and adults of very low intelligence, generally have a "simple childlike faith" that Christians think is good. The problems and irrational features that are found within Christianity are so extreme that typically between the ages of 10 and 15, Christians see that there is something wrong. After that, remaining a Christian involves a continual struggle to suppress doubt.
- Education standards are rising and the scientific method is being taught more effectively. As a result, believers feel less pressure to suppress their doubt, and more incentive to investigate the reasons for their doubt, and to follow where the evidence leads. The evidence leads away from belief in any type of mythology.
You don't need to do anything special to become an atheist or to be an atheist; if you don't believe in a god or gods, you're already an atheist. But still you may feel like doing something to mark your atheist identity. You can always say to yourself or to friends who respect your atheism something like the following.
I no longer believe in a god / I've never believed in a god (whichever is appropriate), and I resolve to base my beliefs upon what the scientific method demonstrates to be true.
Not all atheists are humanists, but if you personally accept humanism then you can make the following affirmation.
I don't believe in a god, and I resolve to follow the scientific method together with humanist morality.
All of this is of course optional; you can be an atheist and a moral humanist without any formal statement.
