Secularization has changed how we think about identity and belonging in today’s world, especially when it comes to religion. As fewer people identify with a religion, new ways of forming identities are appearing.

1. Less Religious Affiliation:

• In the U.S., the number of people who say they are "nondenominational" went from 15% in 2007 to 25% in 2021 (according to Pew Research Center).
• In Europe, countries like the Czech Republic have over 60% of the population identifying as atheist or agnostic, and Sweden has over 70%.

2. New Secular Identities:

• Secularization has created new communities that come together based on shared values, instead of religious beliefs.
• People are starting to identify more with things like their nationality, ethnicity, or social interest groups, moving away from traditional religious ties.

3. Changes in Belonging:

• Nowadays, people often find common ground through shared interests or beliefs rather than religion. This has increased the focus on civic nationalism, which is about being part of a nation rather than a religion.
• Surveys show that 70% of millennials in the U.S. would rather connect with social causes than religious ones, showing a shift in values among younger generations.

4. Cultural Changes:

• In societies that are more secular, traditional religious rituals and symbols are becoming less important. Instead, secular events and celebrations are taking their place. For example, about 30% of weddings in the U.S. recently were led by secular celebrants.
• The growing acceptance of different lifestyles suggests a new way of thinking about belonging, where inclusivity and diversity matter more than ever.

In short, secularization is not just reducing the role of religion in how people see themselves. It is also encouraging new kinds of identities and ways to belong. These changes show a big shift in our culture today.
