The mean generation time is the average age of parents of newborn individuals. It is calculated as the sum of the products of the age of the parents and the number of offspring produced at that age, divided by the total number of offspring produced. In this case, the mean generation time is calculated as (F1F1F1S1F1F1F10x l_xm_x)/R₀, where F1F1F1 is the number of offspring produced by a pair of parents at age x, l_x is the probability of surviving to age x, m_x is the mean age of parents at age x, and R₀ is the net reproductive rate.
