This may seem shocking, but worldwide approximately 10% of all marriages take place between first or second cousins. Above is a map displaying the relative percentages for marriages between first or second cousins for each country (Note: countries in gray mean there is not data). Marriages between cousins are concentrated in the middle east where some countries have as high as 50% of marriages between first or second cousins! The middle east region averages about 1/3 of all marriages to cousins – three times the world average.
