🇺🇸 USA Age-Related Milestones

The United States has numerous age-dependent rights, privileges, and requirements. Most are determined by federal law, though some (like driving age) vary by state. The Social Security Administration, IRS, Medicare, and state DMVs all require precise age verification. American age is calculated from the date of birth as recorded on the birth certificate filed with the state vital records office.
