US Religion Statistics 2023

In most countries, religion plays an important role in making decisions, lifestyles, and even in politics, and most countries have their own statistics about how many percent of their population believes in which religion or how many percent of the population is not associated with any religion.

Religion was always something that changed in time with political ideologies and the situation of the world in general, and we can see this happening in our lifetime again thanks to all these statistics.

The US is no exception to these statistics, and we can see how the United States population’s religious beliefs are changing in time. We will take a look at US religion statistics in 2023.


How Many People in the US Are Believers?

The United States is a major country with its size and its population, and it hosts people from every part of the world.

Why Is There a Rise In Change Of Belief?

Over time, there were major changes in beliefs in the United States. When we look at the statistics, we see that the belief in Protestantism decreased from around 90% in 1900 to 42% in 2020.

We also see an increase in people who has no affiliation with a religion starting from around 2000.

It was close to 0% before 2000 but starting from 2000; we see an increase of around 20%, sitting at 23% in 2020.

These statistics clearly show that people’s beliefs towards religion are changing rapidly, and the reason behind that might be a lot of different things happening in the world and in the political scene of the United States, considering that the world and the USA have gone through many different things from wars to economic crises in the last century.

However, this might also be because of the immigration that the United States has been receiving over the years.

We also see an increase in beliefs in other religions like Buddhism or Islam.

The COVID-19 pandemic in 2020 also affected people’s beliefs about religion, especially among churchgoers.

One of the biggest decreases in religious belief is Protestantism. It decreased to 42% from 90% in around 100 years, which might seem like a long time, but for beliefs to change, this is actually rather a short time period.
