Initially, the C deme maintained a population of 3072 until 4284.369 generations ago. From 4284.369 to 4041.0, its size changed exponentially to population size 7411. A linear decrease ensued, culminating in 1423 individuals by 1990.8. Starting from 1990.8 generations ago, the population has changed from 1423 to 7501, at a exponential rate.
