While Christianity remains the largest religion in Europe, its dominance is declining, particularly in Western Europe, where the share of Christians has been decreasing and the number of religiously unaffiliated people has been growing. This shift is largely due to lower fertility rates, higher death rates among Christians, and a trend of people switching away from religious affiliation.
Many Western European countries have seen a significant decline in the percentage of people who identify as Christian. For example, England and Wales are no longer majority Christian.
