how many world wide christians by denomination

Here’s a practical snapshot of worldwide Christians by denomination :

Denomination / tradition	Estimated followers worldwide
Roman Catholic	About 1.3 billion
Protestant evangelical	Over 420 million
Pentecostal / Charismatic	More than 663 million, with overlap
Orthodox	No single clean global total in the source I found, but Eastern Orthodoxy is often grouped into many distinct churches

These figures come from a recent global Christianity statistical summary, which also says Christians make up about 2.6 billion people worldwide, or 32.3% of the global population.

Important note

The biggest catch is that denomination counts overlap. For example, many Pentecostal and Charismatic Christians are also counted as Evangelicals, so you should not add those numbers together.

Wider context

A broader Pew-based global Christianity report estimated about 2.18 billion Christians in 2010, while more recent global summaries put the total closer to 2.6 billion in 2025.

If you want a cleaner breakdown, I can also format this as:

• Catholic vs Protestant vs Orthodox vs Independent
• Largest denominations by member count
