The sex ratio in the U.S. at birth historically favors males, but it inverts around age 30 due to higher male mortality rates.

Due to homicides and overdoses.

Historically, this is not supposed to happen until 50 (except for periods of wars).

Historically (a while ago) there was always a major surplus of men in all age groups.
Women life expectancy was substantially SHORTER than men due to complications of pregnancy and childbirth.
Only about 200+ years ago, the advancements in gynecology made these problems uncommon so women’s life expectancy suddenly increased a lot!
