The Birth Lottery - 117.6 Billion Lives

Occupational & Class Distribution

Probabilities are birth-weighted across all 117.6 billion lives ever born and normalized to sum to 100%. The overwhelming majority of humans were subsistence farmers. Modern non‑manual occupations collectively represent ~1% of all births. King/emperor sits at ~1 in 333,000 (~0.0003%); slave or bonded laborer at ~4%, reflecting a global birth-weighted average across eras where chattel slavery ranged from near-zero (Paleolithic, most of agrarian Asia) to 10–20% in peak slave societies such as Rome.

Primary demographic model: Kaneda, T. & Haub, C. (2022). How Many People Have Ever Lived on Earth? Population Reference Bureau. prb.org — provides benchmark cumulative births (117.02 billion up to 2022) and period breakdowns.

Total births: 117.6 billion, including 0.58 billion for 2022–2026 estimated from UN World Population Prospects 2024 (~145 million births/year). The "Very Recent" era (2022–2026) reflects current extreme poverty (8.5%), literacy (89%), and child mortality (3.5%).
Era shares: Agrarian Antiquity (8000 BCE–1 CE) accounts for 39% of all births — the single largest era.
Regional distribution: Birth‑weighted synthesis of Maddison Project Database, McEvedy & Jones (1978), HYDE 3.2, and UN World Population Prospects.
Poverty & literacy: Based on Our World in Data (Moatsos, 2021; Roser & Ortiz‑Ospina, 2018) and World Bank (2025).
Child mortality: UN IGME (2025) estimates under‑5 mortality 3.8% in 2022, scaled to under‑15 4.5% for 2022‑2026 average, rounded to 3.5% for the Very Recent era.
Role odds: Normalized to sum to 100%. King/emperor at ~0.0003% (~1 in 333,000), based on an estimated 50–100 new monarchs per year across ~5,000 years of recorded statehood, consistent with R.F. Tapsell, Monarchs, Rulers, Dynasties and Kingdoms of the World (Thames & Hudson, 1983), which catalogs >13,000 rulers. Great-noble-to-king ratio ~257:1. Slave or bonded laborer at ~4%: era-weighted global average anchored on British Museum estimates of 10–20% enslaved in the Roman Empire at peak, with most agrarian births (especially the 46B in Agrarian Antiquity and the 9B in pre-agrarian eras) occurring in societies where chattel slavery was marginal or absent. Artisan at 4%, consistent with craft-sector shares in Maddison Project data. Modern non‑manual occupations total ~0.95%.
