What this topic covers
Capital punishment is the state-authorized execution of a person following a criminal conviction. Its use has changed substantially over time, shaped by constitutional law, legislation, appeals, public opinion and international human-rights standards.
The United States provides a useful case study: the Supreme Court invalidated existing death-penalty statutes in 1972, and a revised framework was approved in 1976. Since then, individual states have determined whether capital punishment remains available, subject to constitutional limits.
This subject cannot be reduced to a single statistic. Any serious comparison should distinguish death sentences from executions, national totals from state totals, and historical records from current law.
