Why the estimates differ

The figure used across this site comes from the Gordon-Conwell Center for Study of Global Christianity 2026, which counts everyone who identifies with any Christian tradition. Pew Research Center's most recent comprehensive estimate reported about 2.3 billion Christians in 2020. The gap is mostly about method and date — how self-identification is measured, how children are counted, and how fast populations have grown since.

Both measure identity, not practice. Neither tells you how many people attend church, read Scripture or follow Jesus as disciples — which is why this site pairs every total with evangelical share, Gospel access and the state of the local church.
