Equality. If the usual parlance were "Gender Inequity" then we'd be talking about that instead. But that's used so little that googling "Gender Inequity" actually redirects automatically to "Gender Inequality", so the former can't be very much in use.

I suggest using “verbatim” on google when google redirects you. Inequity and inequality are two different, precisely defined words.

More than that, equity does speak to exactly what you’re talking about—the egaltarian ideal defined by leveling the outcome, not the opportunity.
