The estimates consider random individuals in the 1960–1965 birth cohort, assumed to be generation $g = 14$ in a 3-epoch model. The standard deviations are standard deviations of the means across accepted parameter sets; means and standard deviations are rounded from Tables 1 and 4. The values for African and European genealogical ancestors appear in Table 3 in Mooney et al. (2023).
