Until 5006.9 generations ago, the H deme's population was fixed at 8365. From 5006.9 to 3606.985, it underwent a linear change to 9595 individuals. Then, a exponential reduction brought the count to 8731 by 977.0. Since then, from 977.0 generations to the current day, the population has reduced from 8731 to 3400 at a linear rate.
