Initially, the G deme maintained a population of 4997 until 5219.06 generations ago. From 5219.06 to 1089.134, its size changed exponentially to population size 3048. A exponential change ensued, culminating in 2709 individuals by 466.0. Starting from 466.0 generations ago, the population has decreased from 2709 to 1411, at a exponential rate.
