Does there exist a percentage of a population that can be safely sacrificed or otherwise "disappeared" and still maintain a steady population growth?
For example. Could a village of 1000 people (500 adult men and 500 adult women) steadily sacrifice a portion of its population and still maintain a growth?
Of course biological sex plays a heavy role here. If a villge loses half of its males, it can recover within a few generations. However if the village lost half of it`s women, it would take much longer.
