Until 9597.0 generations ago, the G deme's population was fixed at 4617. From 9597.0 to 6968.7317, it underwent a linear growth to 7846 individuals. Then, a exponential change brought the count to 4380 by 6824.0. Since then, from 6824.0 generations to the current day, the population has decreased from 4380 to 2877 at a exponential rate.
