20 Least Religious Cities in the United States

These 20 least religious cities in the United States probably have the most people that don’t attend church. Religion remains a hot topic in all platforms today, especially the internet. Just one mention of something spiritual or religion related can spark an endless debate with most people not agreeing with one another. Religion remains a sensitive topic. One of the things that damages it the most, is the presence of extremists that seem to pour out a lot of hate and negativity, opposite to what most groups do. Though the US remains relatively high in terms of people who are religious, the rate of unaffiliated citizens seems to be slowly increasing with each year.

You may find that this list is the complete opposite of The Most Religious Cities in America. Unlike those cities, the cities here are often found with people who don’t necessarily affirm with a religion. This doesn’t mean that their beliefs are non-existent but they probably have difference in opinions compared to most religions which is why they’ve declared themselves as such. It seems that most of the time, too much diversity in terms of religion has left some confused and others mislead.

9. Detroit

Percentage of Unaffiliated: 24%

In order to revitalize churches in Detroit there has been a movement called the “Mass Mob”. They harken themselves as similar to “Flash Mobs” in terms of having a large group or mob participate.

8. Columbus

Percentage of Unaffiliated: 24%

Unlike some cities in this list that still have majority in a certain religious affiliation, Columbus finds itself as one of the cities where the unaffiliated fill the majority. One of the reasons for this maybe the lack of religious venues in the city compared to other places in the US.

Percentage of Unaffiliated: 26%

The unaffiliated in Phoenix is the highest it’s ever been and for many it is because they find religious institutions no longer relevant. Others find them damaging to their beliefs.

1. Portland

Percentage of Unaffiliated: 42%

The city that is least religious due to a high percentage of unaffiliated is Portland. Almost half of their population is declared unaffiliated and the difference between Portland and the next city is a large 9%. It is said that Portland isn’t the only city like this in Oregon but most cities and areas of the state as well.

One of the main reasons why a lack of affiliation is popular in today’s society is because a lot of religious groups often associate and adhere to beliefs and practices that often don’t feel right for people. Often times, people search for spirituality and go to church in search of answers for their problems. When the institution they attend, however, discourages or gives them guilt, they then find themselves not wanting to attend other ones as well.

This is not of course considering the fact that there are some people who genuinely believe in being agnostic or atheist. The real sad thing about all of this is that people are more concerned about debating each of their beliefs than just getting along and respecting each others’ views. People will discover and set their heart and mind on something on their own terms. If history’s any indication, you cannot change people’s minds by convincing or debating with them. You must let them come on their own terms to accept what they want to accept.

This has been the 20 least religious cities in the United States. Whether that’s good or bad is up to you.
