The rank-size rule is not valid for the country of Yemen. Yemen most populated city, Sana'a, has a population almost 3 times larger than that of the next largest city of Adan. This is because Yemen has had a history of colonization with both the Ottoman Empire and United Kingdom after WWI. The colonizers most likely developed the most established city at the time which was Sana'a into the center point of development for the country. This trend continued which resulted in Sana'a remaining the most populated city when compared to the others. Sana'a has the most resources and jobs available which has attracted many immigrant from the Arabian Peninsula and North Africa. However, a recent civil war has left large portions of the city in ruins and decreased the population. It is likely than Sana'a had an even larger population one decade ago.
