Populations do not grow arithmetically, they grow—not unlike credit card debts—exponentially. The Afrikaners in South Africa started from a group of about 2,000 settlers who came in the late 17th century. Today, roughly 13 generations later, they number about three million. A little over three hundred years ago, five thousand French immigrants came to Quebec; their descendants now number about 6.5 million. What needs to be explained is not why the Jewish population in Eastern Europe grew exponentially in the modern period but rather why the Jewish population of Central Europe did not grow. But that is a different question, and the Khazars are of no help in solving it.
