| 800 | 11 | 6-10 | McEvedy & Jones 1978 | Classic period, near peak |
| 900 | 12 | 8-12 | McEvedy & Jones 1978 | Classic period peak, collapse begins |

| 1200 | 8 | 4-7 | McEvedy & Jones 1978 | Post-Classic, population recovery begins |
| 1500 | 15 | 8-12 | McEvedy & Jones 1978 | Post-Classic, pre-contact peak |
Comparative Context
- Regional average (Americas, 900 CE): ~15 million
- Global average (900 CE): ~240 million
- Ranking: Moderate population globally (500-1500 CE)
- % of world population (900 CE): ~5%
- % of world population (1500 CE): ~6%
- Comparison to other civilizations (900 CE):
- Sinitic: ~0.2x (Sinitic ~59 million)
- Islamic: ~0.25x (Islamic ~48 million)
- Population density comparison: Moderate density (8-12/km²) for pre-modern period
Key Events
- 500-900 CE: Classic period expansion - Population growth (5M → 12M peak), urbanization, economic prosperity
- 900 CE: Classic period peak - Population peak at 12M, collapse begins
- 900-1200 CE: Classic collapse period - Population decline (12M → 8M), environmental challenges, warfare
- 1200-1500 CE: Post-Classic recovery period - Population recovery (8M → 15M), Aztec expansion, pre-contact peak
- Event-data integration: Population fluctuations (5M → 12M peak → 8M → 15M) linked to Classic period expansion (500-900 CE), Classic collapse (900-1200 CE), and Post-Classic recovery (1200-1500 CE), with environmental challenges and warfare affecting population dynamics

About this entry
A draft entry preserved from civilization.study. Evidence grade: weak. 2 of 2 listed sources are fully documented; the rest are names only. † marks figures that are scholarly estimates. Method and sources
Methodology Notes
- Estimation method:
- McEvedy & Jones (1978) provides rough estimates based on archaeological settlement data and carrying capacity models
- Archaeological evidence (settlement size, number of cities, urban population) - primary source
- Carrying capacity models (maize productivity, agricultural capacity)
- Historical records (very limited, primarily post-contact)
- Data quality: Weak (very limited historical records, primarily archaeological estimates with high uncertainty)
- Uncertainty range: ±30-40% (high uncertainty due to limited data, archaeological estimates)
- Limitations:
- Very limited historical records for this period
- Archaeological estimates have high uncertainty
- Regional variation within Mesoamerica not fully captured (Maya, Aztec, other regions)
- Age structure, fertility, and mortality data unavailable
- Urban vs. rural population breakdown uncertain
- Cross-validation:
- Archaeological settlement data (city size, number of cities, urban population)
- Agricultural carrying capacity (maize productivity, cultivated area, chinampas)
- Historical records (very limited, primarily post-contact)
Integration with Corpus
- Links to claims: Mesoamerican Civilization (supports GGS assessment)
- Supports patterns:
- Guns–Germs–Style (GGS) Axes and Success/Failure Mechanisms (population dynamics support Style axis - urban coordination, administrative capacity; population decline 900-1200 CE linked to failure modes)
- Disease Ecology and Civilizational Transformation (population decline 900-1200 CE may be linked to disease ecology, environmental challenges)
- Population Dynamics and Civilizational Capacity (population size and density affect civilizational capacity)
- GGS implications:
- Style axis: Moderate population (5-15 million) requires and demonstrates institutional capacity (urban coordination, administrative capacity, resource management)
- Germs axis: Population decline (900-1200 CE) may be linked to disease ecology, environmental challenges, or other factors (Germs axis interaction)
- Economic capacity: Moderate population enables economic specialization and surplus generation (agricultural surplus, craft specialization, urban centers)
- Military capacity: Moderate population provides limited military potential (Guns axis), though effective military organization
- Framework integration:
- CAD: Social domain, persistence/transformation/failure mechanisms, Germs and Style frameworks
- Demographic patterns: Supports Demographic Patterns Across Civilizations with quantitative evidence (population fluctuations, Classic collapse)
- Failure modes: Population decline 900-1200 CE supports failure mode analysis in Guns–Germs–Style (GGS) Axes and Success/Failure Mechanisms
Notes
- Demographic structure: No data on age structure, fertility, and mortality for this period
- Population fluctuations:
- 500-900 CE: Population growth (Classic period, urbanization, economic prosperity)
- 900-1200 CE: Population decline (Classic collapse, environmental challenges, warfare)
- 1200-1500 CE: Population recovery (Post-Classic, Aztec expansion, pre-contact peak)
- Regional variation: Core regions (Valley of Mexico, Maya lowlands) higher population density than periphery
- Urbanization: Significant urban population (estimated 15-25% in major cities - Teotihuacan, Tikal, Tenochtitlan)
- Classic collapse: Population decline 900-1200 CE linked to multiple factors (environmental degradation, warfare, disease, climate variability)
- Data needs: More archaeological settlement data, agricultural productivity estimates, urban vs. rural breakdown, disease ecology data
