Uncover the surprising truths behind cousin marriage and its global prevalence.
Shocking data shows consanguinity occurs in approximately 10% of marriages worldwide, with some countries like Pakistan occurring in at least half of all marriages.
But what are the real health and societal impacts?
In this eye-opening episode, economist Munir shares groundbreaking research using 40 million genealogical histories from the US, revealing that children of cousin marriages face a five-year reduction in lifespan, with effects extending throughout life, not just childhood. You'll discover how cultural, economic, and societal factors sustain these practices, even in wealthy nations with strong education systems, challenging common assumptions.
