Abortion’s Real Population Impact

Naïve counts imply roughly a quarter of post‑1973 generations were 'missing' due to abortion, but behaviorally adjusted estimates suggest abortion access reduced births by only about 3–6%. When you propagate those extra births forward (because saved babies later have their own kids), the total rises to roughly 7.6–15.3 million additional births from 1973 to 2020. This reframes the scale of abortion’s demographic effect from headline ratios to realistic net population change. — It grounds a polarized debate in tractable magnitudes that matter for labor force, entitlement math, and long-run population policy.
