Christians in Africa and Latin America tend to pray more frequently, attend religious services more regularly and consider religion more important in their lives than Christians elsewhere in the world, a recent Pew Research Center study has found.
At the same time, Christians in the United States also have comparatively high levels of commitment to their faith.
Christianity is the world's largest religion, with a big presence in most parts of the globe. But not all Christians share the same levels of religious commitment, the Pew research finds.
Among Christians, religion most important in sub-Saharan Africa, Latin America, and the United States, the study which was released on August 22 found.
The study analyzed 84 countries with sizable Christian populations.
In 35 of those countries, at least two-thirds of all Christians say religion is very important in their lives. All but three of these 35 countries are in sub-Saharan Africa or Latin America.
The three exceptions are the United States, Malaysia and the Philippines.
Among Christians, worship attendance and prayer frequency highest in sub-Saharan Africa, lowest in Western Europe.
Levels of religious salience are particularly high in sub-Saharan Africa: Over 75 percent in every country surveyed in the region say religion is very important to them.
At the other end of the spectrum, levels of religious importance are lowest among Christians in Europe, where deaths outnumber births among Christians.
These findings reflect the broader pattern of Christianity's "march southward" from wealthy countries to developing ones which a number of recent studies have found.
This phenomenon is particularly evident in sub-Saharan Africa, where Christianity is rapidly growing, largely due to high fertility rates.
Still, the United States remains an outlier among wealthy countries in terms of its relatively high levels of religious commitment.
In the U.S., more than two-thirds of Christians say religion is very important in their lives, compared with significantly lower levels in other rich democracies.
For instance, only 12 percent of Christian adults in Germany and 11 percent in the United Kingdom say religion is very important in their lives.
Christians in Africa and Latin America also tend to pray and attend church at higher rates than Christians in most of the rest of the world.
For instance, at least four out of five Christians in Nigeria, Liberia, Senegal, Cameroon and Chad pray every day.
Prayer frequency is just as high in six Latin American countries, including Guatemala, Honduras and Paraguay.
Similarly, in every African country surveyed, more than 60 percent of Christians say they attend church at least weekly.
In Latin America, more than two-thirds of Christians in Guatemala, Honduras and El Salvador also report weekly attendance.
Prayer frequency is lowest among Christians in Austria, Germany, Switzerland, the UK and Malaysia, where fewer than 10 percent of Christians pray daily.
Likewise, fewer than 10 percent of Christians report attending church weekly in nine European countries, including Denmark, Estonia and Russia.
