AL SB79

Amends Alabama Code Section 1-1-1 to define sex-based terms including "male," "female," "man," "woman," "boy," and "girl" based on reproductive system characteristics or as observed at birth.

Establishes legislative findings that there are only two sexes (male and female), that sex is objective and fixed, and that individuals with differences in sex development are not a third sex but must be accommodated under state and federal law.

Permits state and political subdivisions to establish separate single-sex spaces or environments for males and females when biology, privacy, safety, or fairness are implicated.

Requires school districts, public schools, state agencies, and political subdivisions that collect vital statistics related to sex to identify each individual as either male or female, with an exception allowing "unknown" to be entered when sex cannot be medically determined at birth.

Takes effect October 1, 2025.
