Until 8934.98 generations ago, the X deme's population was fixed at 9693. From 8934.98 to 5381.5975, it underwent a exponential change to 6214 individuals. Then, a exponential increase brought the count to 7969 by 1824.1. Since then, from 1824.1 generations to the current day, the population has reduced from 7969 to 5039 at a exponential rate.
