What Percentage Of Americans Are Christian?

Let’s talk about how many Christians are in America.

~63% of Americans are Christian (Pew Research). 

Meaning there are 207.9 million people who are Christians in America.

330,000,000 x 63% = 207,900,000 people who identify as Christians.

(The world population is ~330M.)

They used phone interviews with a nationally representative sample of adults.

How Many People Practice Christianity?

Figuring out how many people in America “practice Christianity” is challenging.

This is because “practicing” can mean different things to different people. 

Surveys that measure religious activities (i.e., church attendance) give us some idea.

One survey says that ~45% of Americans attend religious services at least once a month.

But this includes all religions, not just people practicing Christianity.

Now, we also know that ~63% of Americans are Christians. 

330,000,000 x 45% = 148,500,000 people who practice Christianity in America.

That means that 69.2% of Christians attend church at least once a month. 

This method doesn’t consider other aspects of practicing Christianity, such as:

  • personal prayer 
  • following moral principles

“Practicing Christianity” can be defined in various ways, depending on:

  • individual beliefs
  • religious teachings
  • cultural factors 

Common criteria of “practicing Christianity” include:

  • belief in core Christian doctrines
  • regular participation in worship and communal activities
  • personal prayer
  • adherence to moral and ethical principles
  • commitment to sharing faith
  • acts of service and charity

Why Is Christianity Declining In America

The percentage of Americans who are Christian declines by ~0.74% per year.

We used the table in the next section to calculate this decline. 

(Average decline) = ((Final percentage – Initial percentage) / (Number of years)) x 100%

((63.0% – 85.0%) / 30 years) x 100% = -0.74% per year

The number of Christians in America is declining, but why? 

Here are the main reasons Christianity is declining in America:

  • More Diversity: People from different religious backgrounds are coming to the U.S., making the population more varied.
  • Less Religious: More Americans, especially younger ones, don’t identify with any religion or consider themselves atheist or agnostic.
  • Less Focus On Religion: Religion’s role in public life has decreased, making it less important for some people.
  • Changing Values: Society’s attitudes on moral and social issues have changed, and some people may not agree with traditional religious teachings.
  • More Religious Options: With more exposure to various beliefs, people can choose from many different religions or no religion at all.
  • Trust Issues: Scandals and corruption in religious institutions can make people lose faith in them.

Why do people become more religious as they age? 

  • Major life changes make people think more deeply about the meaning of life and seek out religious beliefs.
  • Awareness of mortality can lead people to turn to religion as a way to cope with uncertainty.
  • Religious communities provide social support and become more important as people age and face isolation.
  • Older adults may have more life experience that allows them to appreciate and value spiritual or religious beliefs more.

The age distribution of Christians in the US varies by denomination. 

In general, mainline Protestant and Catholic populations tend to be older.

Evangelical Protestant and historically Black Protestant populations tend to be younger. 

But, there is a trend across all Christian denominations.

Younger generations are less likely to identify as Christians compared to older generations.

(i.e., Millennials and Generation Z vs Baby Boomers and the Silent Generation.)

Compare that to only 17% of those ages 50 and older. 

7% of Americans ages 18 to 29 identified as members of non-Christian religions.

Compare that to only 2% of those ages 50 and older.

There are generational differences in religious identification in the US. 

This trend has important implications for the future of religion in the US.

Younger generations will likely shape the religious landscape in the coming years.
