Age-gap research
Explore demographic findings, primary sources and the limits of using population data to understand an individual relationship.
Start with the statistics overview
Our statistics page summarizes U.S. spousal age-difference findings from Pew Research Center and the U.S. Census Bureau. It clearly separates the year a dataset describes from the year an article was published.
How we use research
We prioritize government data, peer-reviewed studies and established research organizations. Population findings are presented as context, not as a compatibility score or personal prediction.
Important limitations
Age-gap patterns vary by country, culture, age at marriage, remarriage, couple type and research definitions. Averages are descriptive and should never be treated as a recommended target.
Calculation transparency
Research pages discuss population patterns, while our methodology page explains the date arithmetic used by the calculators.
