East Africa's first large-scale wave of immigrants, excluding mercenaries, arrived in 1865. After that, immigration numbers rose in a straight line, and as East Africa's transport capacity increased, the scale grew ever larger.
In other words, the first immigrants had settled down in East Africa for nine years, and the nature of East African immigration meant that the current East African population had already exploded.
This could be compared to the German territories. Fertility rates in the German territories were already quite high, but East Africa's were even higher, because East Africa bore the costs of childbearing—a thing impossible in the German territories.
Land in Germany had been carved up among nobles and landlords. Coupled with the development of capitalist agriculture, the pursuit was no longer labor and landholding rates, but profit above all else.
Although East African land was likewise privately owned, Ernst's previous focus had been on giving East African citizens relatively good treatment. One aspect of this was his hope that East African residents would have as many children as they could, with the state bearing most of the costs of childbirth.
Naturally, East African citizens free of the burden of childbearing costs had as many children as they could, especially when there was neither the concept of contraception nor any means of it.
As long as people were basically healthy, fertility rates would not be low. Coupled with an extremely low infant mortality rate compared with other countries, East Africa's population would ultimately multiply severalfold.
At low levels of productivity, most of these costs were ultimately borne by the Black population. East Africa had twenty million Black people, with the working population numbering more than ten million.
Thus, East Africa did not currently feel much pressure. However, it was also reducing its Black population at a
