WebTo calculate the number of individuals that will survive to the next time period, we multiply the number of individuals in each age class (Nx) by the survival rate (Sx) for the age class. Thus, to determine the number of newborns that will survive to be 1-year-olds in the following year, we multiply No =20 by So =0.3 to get 6 1-year-olds. WebProduct Description.
