The share of people who identify as religious has fallen across many Western countries

Debates over whether religion is booming or dying are common. What does the data say?

Most countries lack long-term data on religious identity, but results from the Pew Research Center offer insights into changes over the decade from 2010 to 2020. (Unfortunately, 2020 is the most recent year for which we have comparable global data.)

At a global level, there was barely any change. The share of people identifying with any religion dropped by just one percentage point, from 77% to 76%.

But religious affiliation did drop significantly across many countries in Europe, the Americas, and Oceania. You can see this drop for a selection of countries in the chart.

In Australia, rates dropped from 75% to 58%. In the United States and Chile, the percentage has decreased from roughly 85% to 70%.

So while religious affiliation is stable in many parts of the world, this data shows religion is becoming less prominent in others.

Note that this data is based on self-identification with any religion; it doesn’t tell us about changes in practices or rituals, such as prayer or attending services.
