How would the overall population so each side affect the rate of attrition?

The overall population size on each side can significantly influence the rate of attrition. A larger population may lead to a lower attrition rate, as there are more individuals to replace those who leave, fostering a sense of stability. Conversely, a smaller population can result in a higher attrition rate, as each departure has a more pronounced impact, potentially leading to a cycle of instability and increased turnover. Additionally, factors such as engagement and satisfaction levels within each population can further modify these effects.
