Global Patterns and Economic Development
Population distribution
Population distribution reflects the uneven spread of people across the Earth's surface, influenced by physical factors (e.g., climate, topography) and human factors (e.g., economic opportunities, governance).
- The level of economic development level is related to the population distribution in a significant way, with LICs, MICs, and HICs exhibiting distinct economic and demographic characteristics.
Low-Income Countries (LICs): Rural Dominance and High Population Growth
- LICs have predominantly rural populations due to prevailing role of subsistence agriculture.
- Urban areas are fewer and less developed, limiting benefits of rural-to-urban migration.
- Consequently, LICs often experience high population growth rates but low levels of urbanization.
- Population pressures on resources experienced by LICs are also influenced by factors such as high fertility rates, poor access to education and healthcare which deepen rural poverty cycles.

- In Niger, over 80% of the population resides in rural areas, where access to basic services like healthcare, education, and infrastructure is limited.
- Very high fertility rates (nearly 7 births per woman) further exacerbate resource pressures, perpetuating poverty in rural communities.
- When analyzing LICs, focus on the relationship between agricultural viability and settlement patterns.
- Fertile land and water access are often the primary factors driving population distribution.
Middle-Income Countries (MICs): Urbanization Fueled by Industrial Growth
- MICs typically undergo significant economic and demographic transitions.
- Industrialization drives job creation in cities, prompting rural-to-urban migration.
- The urban centers that arise from such changes offer higher wages, better education, and improved healthcare, making them attractive destinations for migrants.
- MICs are also very diverse as they constitute ~50% of all countries hosting ~75% of global population. For that reason they are divided further into two sub-categories:
- Upper Middle-Income Countries: Rapid Urban Growth Through Economic Diversification and Increased Investment, e.g. Brazil, China, Namibia
- Lower Middle-Income Countries: Struggling with Urbanization Amidst Economic and Social Changes, e.g. Bolivia, Egypt, India.
- Finally, MICs are characterized by significant inequalities.

- It’s a common misconception that urbanization in MICs is evenly distributed.
- In reality, migration typically concentrates in a few key cities, leaving rural areas relatively unchanged.
High-Income Countries (HICs): Stable Urban Patterns and Aging Populations
- HICs are countries that generally have stable population distributions, with most people living in urban areas.
- These countries benefit from well-developed infrastructure, diversified economies, and lower population growth rates.
- However, aging populations are a defining feature, often resulting in slower urban expansion and rural depopulation.

- In Japan, urban regions like Tokyo, Osaka, and Nagoya dominate population patterns.
- Meanwhile, rural areas face depopulation as younger generations migrate to cities, leaving behind aging communities.
In HICs, population distribution is less about survival needs and more about quality-of-life factors, such as access to healthcare, education, and cultural amenities.
Economic Classifications of Countries Attempt to Capture More Nuance
- At its most basic, countries are often grouped into rich and poor categories or into income groups explained above (LICs, MICs, and HICs).
- While this is a simple way to look at the world, it doesn’t capture the full picture.
- More detailed classifications are used to better understand how countries are developing.
1. More Economically Developed Countries (MEDCs)
- Countries like Japan and Germany are highly developed, with strong economies and high living standards.
- In other words, these are High-Income Countries (HICs).
2. Newly Industrialized Countries (NICs) and Recently Industrialized Countries (RICs)
- These are countries like Malaysia and Taiwan that have grown quickly in industry since the 1960s (NICs) or later, since the 1980s/1990s (RICs) like China, India or Thailand .
- Some NICs, such as Singapore and South Korea, have already become HICs.
- Further examples include:
- BRICS: Countries like Brazil, Russia, India, China, and South Africa are known for their rapid growth, vast resources, and development potential.
- MINT: Mexico, Indonesia, Nigeria, and Turkey are also showing fast development.
3. Emerging Economies
- Emerging economies are nations experiencing rapid economic growth and industrialization while transitioning originally from low-income to more advanced economic status.
- These countries typically exhibit increasing integration into the global economy, improving infrastructure, and rising living standards.
- They are usually characterized by large domestic market and rapid rural-to-urban migrations.
- Emerging Economies are mostly Middle-Income Countries (MICs).
- Examples include BRICS excluding Russia, Indonesia, and Turkey.
