As humans reproduce and spread across the land, they naturally reside in areas best suited for agriculture and industry. Areas unsuitable for agriculture, including dry and remote island areas, logically attracted the fewest number of settlers. As a result, in modern times when people began to divide the world into countries, the smallest area usually became the least populated country.
