Until 9432.0 generations ago, the G deme's population was fixed at 9117. From 9432.0 to 7084.5, it underwent a exponential change to 6504 individuals. Then, a linear change brought the count to 5815 by 6061.15. Since then, from 6061.15 generations to the current day, the population has changed from 5815 to 2618 at a exponential rate.
