Human fertility increases with marital radius.
We report a positive association between marital radius (distance between mates' birthplaces) and fertility detected in a large population. Spurious association due to socioeconomic factors is discarded by a conditional analysis involving income, education, and urbanicity. Strong evidence of consanguinity's deleterious effects affecting an entire human population is provided.
