Most people marry someone of the same religion, Facebook suggested in a recent study.
Facebook data scientist Mike Develin using research of romantic relationships of those aged 21 or older with self-identified religions, wrote a report showing that most people marry within their religions. Even the country most lax about interfaith marriage, Spain, only had 28 percent of interfaith relationships.
Despite prevailing notions, this endogamy existed across all continents including the United States, Asia and Europe. The United Kingdom, for instance has 73 percent same-religion relationships. In Taiwan, with dozens of religion, the numbers are even higher -- 90 percent. In the United States, that number is 86 percent.

However, most of those dating those of other religions tend to be in their 20s, and are more likely to date someone of a different religion than to marry them.
