Government Evacuation in Times of War/National Emergency

[Mortblanc]

That's a whole different kind of evacuation CH.

What the OP is referring too is the large scale relocation of large segments of the population on a permanent or long term time frame "for their protection" or for control.

Removal of the children from the cities was supposedly for their safety during the blitz, but it also furnished a small labor force for the farms in rural areas, and freed the urban population from the burden of child care, allowing them to work longer hours in riskier situations and increase war production.

It has also been found useful for the control of insurgent activity among population groups and was the primary feature of our Indian Removal Act and Reservation system for the Indians.

It was also used very successfully by the British in South Africa during the Boer War, in Malaysia after WW2 and was the theory behind the "Pacification Program" for villages in Viet Namn.
