Besides the ratio between what the top 20% have, another measure of inequality is the [https://en.wikipedia.org/wiki/Gini_coefficient GINI coefficient] which measures how much the distribution of wealth deviates from equal distribution with a GINI of 0 being equal distribution.
Besides the share of wealth of the top 20%, another measure of inequality is the [https://en.wikipedia.org/wiki/Gini_coefficient GINI coefficient] which measures how much the distribution of wealth deviates from equal distribution with a GINI of 0 meaning equal distribution.
A study analyzing GINI coefficients in human [[relationship|relationships]] found that “single men have a higher Gini coefficient (.536) than single women (.470). Thus, female sexual partners are more unequally distributed among single men than male sexual partners are among single women”<ref>https://contexts.org/blog/who-has-how-many-sexual-partners/</ref>.  This roughly corresponds to the top 20% men having 60% of the sex, so 60/20, and 56/20 for women (i.e. less extreme than 80/20, in the general population at least).<ref>https://en.wikipedia.org/wiki/Pareto_distribution#Lorenz_curve_and_Gini_coefficient</ref>

Mark Regnerus estimated the distribution to be 20/70 for men older than 25.<ref>https://books.google.de/books?id=928uDwAAQBAJ&pg=PA86&lpg=PA86&dq=%22Pareto+would+be+proud,+or+nearly+so%22&source=bl&ots=jErxDCkmJ4&hl=en&sa=X#v=onepage&q=%22Pareto%20would%20be%20proud%2C%20or%20nearly%20so%22&f=false</ref> Data from GSS also suggests it is around 20/68 for men and a bit less unequal, 20/59 for women.{{citation needed}}
