4. Urbanization (n) la urbanización
The increasing proportion of a population living in towns and cities, driven by rural-to-urban migration.
Push/Pull Factor Behind Growth:
Trend: Rapid Growth Impact: Megacities
5. Primate City (n) ciudad primada
A city that is disproportionately larger than any other in its nation (more than 2x next city) and dominates its culture and economy.
Primacy Rule & Latin American Example:
Criteria: 2x size of City #2 Ex: Mexico City / Lima
Economic Disparity & Spatial Migration
Core vs. Periphery Dynamics
6. Uneven Development (noun) el desarrollo desigual
The unequal distribution of people, wealth, and technological infrastructure across distinct geographic regions.
Core vs. Periphery Contrast:
Visible Evidence: Paved roads/hospitals vs. dirt roads/poverty
7. Brain Drain (noun) la fuga de cerebros

Impact on Origin Country:
Affected Occupations: Physicians, engineers, researchers
Agricultural Systems: Economic Production Comparison
Subsistence vs. Commercial Matrix
8. Subsistence Farming (noun) agricultura de subsistencia
Farming designed primarily to provide food for direct consumption by the farmer and family, with little or no surplus for sale.

Exemplar Student Responses
1. Isthmus (noun) el istmo
A narrow strip of land bordered by water on both sides connecting two larger land masses.
ACCEPTABLE REWRITE:
A natural land bridge between two continents that creates a strategic choke point and trade corridor.
Key Words: Land bridge, water on both sides, connects continents
Exemplar Example: Isthmus of Panama (Panama Canal)
2. Deforestation (noun) la deforestación
The permanent clearing and destruction of forests for cattle ranching, timber, or commercial agriculture.
ACCEPTABLE REWRITE:
Massive cutting or burning of forest biomes, leading to biodiversity loss, soil erosion, and carbon emissions.
Key Consequences: Carbon release, habitat destruction, topsoil loss
Vulnerable Region: Amazon Basin (Brazil cattle / soy farms)
Settlement Systems: Rural to Urban Shift
Demographic Models & Primacy
3. Rural (adj) campo/rural
Countryside areas with low population density and primary resource economies.
Look-Fors:
Open land, dispersed homesteads, primary sector (farming, mining, forestry).
Density: Sparse Economy: Primary
4. Urbanization (n) urbanización
Increasing share of national population living in towns and cities.
Key Drivers:
Push: Rural poverty, farm machines. Pull: Industrial jobs, healthcare, schools.
Trend: Megacities Challenge: Favelas
5. Primate City (n) ciudad primada
A city over 2x larger than the next city that dominates national life.
Primacy Criteria:
Pop > 2 × City #2; concentrates all government, finance, and culture.
Rank-Size: Violated Ex: Mexico City, Lima
Economic Disparity & Spatial Migration
Core vs. Periphery Dynamics
6. Uneven Development (noun) desarrollo desigual
The unequal distribution of people, wealth, and technological infrastructure across distinct geographic regions.
CORE VS. PERIPHERY ANALYSIS:
National wealth and capital concentrate in urban cores, while rural peripheries lack paved highways, hospitals, and high-speed tech.
Indicators: Regional GDP gap, infrastructure divide, HDI disparity
Visible Evidence: Gated luxury towers adjacent to informal barrios
7. Brain Drain (noun) la fuga de cerebros
The large-scale emigration of highly educated or skilled professionals from developing regions to wealthier nations.
SYSTEMIC IMPACT:
Deprives home nations of human capital (doctors, engineers, researchers), hindering local healthcare and technological innovation.
Push/Pull: Low local wages & instability vs. high salaries abroad
Typical Flow: Latin America / Caribbean → US / Europe
Agricultural Systems: Economic Production Comparison
Subsistence vs. Commercial Matrix
8. Subsistence Farming (noun) subsistencia
Farming designed primarily to provide food for the farmer and family, with little or no surplus for market sale.
CORE CHARACTERISTICS:
High share of population in agriculture; small family-owned plots; manual/animal labor; staple crops (maize, beans, cassava).
Purpose Survival / Family
Scale Small plots
Machinery Manual tools
9. Commercial Farming (noun) comercial
Large-scale farming designed primarily to generate surplus crops or livestock for commercial sale, profit, and export.
CORE CHARACTERISTICS:
Low labor percentage (heavily mechanized); vast monoculture fields; integrated into multinational agribusiness (soy, beef, coffee).
Purpose Profit / Export
Scale Vast plantations
Machinery High automation
