From Consanguinity and increased risk for schizophrenia in Egypt:

“3.4. Consanguinity by area of residence – Individuals living in villages or small towns (population less than 10,000)were classified as rural dwellers (65% of cases and 73% of controls), while the remainder were considered urban residents. The rates of self-reported consanguinity were similar among cases (36.11% among rural and 38.10% among urban groups) and controls from both groups (17.14% among rural and 20% among the urban control groups).”

Total consanguinity rate = 19.8%

Urban consanguinity rate = 20%
Rural consanguinity rate = 17.14%
