Pew-Templeton Global Religious Futures Project

Pew Research Center has analyzed restrictions on religion around the world for 10 years, finding that global restrictions have risen. What is happening in some of the countries with the biggest changes?

Giving a share of one’s income to the church has been a part of European tradition for centuries. Today, several countries continue to collect a “church tax” on behalf of officially recognized religious organizations, in some cases levying the tax on all registered members.

People who are active in religious congregations tend to be happier and more civically engaged than either religiously unaffiliated adults or inactive members of religious groups, according to a new Pew Research Center analysis of survey data from the United States and more than two dozen other countries.

The European continent today is split in public attitudes toward religion, minorities and social issues such as gay marriage and legal abortion.

Restrictions on religion increased in 2016 for the second straight year. Nationalist parties and organizations played an increasing role in harassment of religious minorities, especially in Europe.

Young adults tend to be less religious than their elders by several measures; the opposite is rarely true. This pattern holds true across many countries that have different religious, economic and social profiles.

The majority of Europe’s Christians are non-practicing, but they differ from religiously unaffiliated people in their views on God, attitudes toward Muslims and immigrants, and opinions about religion’s role in society.

Even with no new migration, Muslims are projected to increase as a share of Europe's population.

Concentrated in Europe, Orthodox Christians have declined as share of the global Christian population, from 20% in 1910 to 12% today. But the Ethiopian community is highly observant and growing.

Islam is the most common state religion, but many governments give privileges to Christianity.
