Sentencing Lengths Inflate Prison Rates

Cross‑country conviction rates can be similar while prison populations differ dramatically because of sentence duration: short, frequent sentences (e.g., Denmark) produce many convictions but low daily prison counts, whereas long sentences (e.g., United States) make prison populations much larger per capita. That means debates about 'how many are criminals' or 'why the U.S. incarcerates more' should focus as much on sentencing policy as on raw crime incidence. — Reframing mass‑incarceration debates to emphasize sentence length changes the target of reform from vague 'crime reduction' to concrete sentencing and parole policy, with implications for budgets, racial disparities, and immigration politics.
