Less Developed Countries

Less Developed Countries (LDCs) are nations with lower industrialization, lower standards of living, and lower Human Development Index scores than developed countries, typically marked by large agricultural or informal sectors, high fertility and infant mortality rates, and dependence on exporting raw materials.

What is Less Developed Countries?

A Less Developed Country (LDC) is a country that scores low on the standard measures of development you learn in Topic 7.3. Think low GNI per capita, low literacy rates, high fertility and infant mortality rates, limited access to health care, and a low Human Development Index (HDI) score. Economically, LDCs tend to have a large primary sector (farming, mining, raw materials) and a big informal economy, while developed countries have shifted toward services.

Here's the mental model that makes the term click. LDCs are roughly the 'periphery' in world systems theory. They supply raw materials and cheap labor to the global economy, and in return they often get lower-paying jobs through the international division of labor (EK PSO-7.A.6). You'll also see the labels 'developing countries,' 'periphery,' or 'Global South' used as near-synonyms. The AP exam cares less about the label and more about whether you can read development data and explain the spatial patterns behind it.

Why Less Developed Countries matters in AP Human Geography

LDCs sit at the heart of Unit 7 (Industrial and Economic Development). Learning objective 7.3.A asks you to describe social and economic measures of development, and 'less developed' is literally defined by those measures, GDP and GNI per capita, sectoral structure, fertility rates, infant mortality, literacy, and HDI. LOs 7.6.A and 7.7.A then ask you to explain how trade, neoliberal policies, international lending agencies like the IMF, and outsourcing reshape these countries, including the rise of special economic zones and export-processing zones outside the core.

But the term doesn't stay in Unit 7. In Unit 5, LDCs are where subsistence and extensive practices like shifting cultivation and nomadic herding persist (5.1.A), and where commodity chains pull plantation crops toward consumers in wealthy countries (5.7.A). In Unit 6, LDCs are where primate cities and rapid urban growth show up (6.4.A). If you can move the LDC concept across all three units, you're doing the cross-scale thinking FRQs reward.

How Less Developed Countries connects across the course

Human Development Index (HDI) (Unit 7)

HDI is the main yardstick that sorts countries into 'more developed' and 'less developed.' It blends income, education, and life expectancy into one score, so a low HDI is basically the formal definition of an LDC on the exam.

Globalization and the International Division of Labor (Unit 7)

Outsourcing moves manufacturing jobs from core countries into LDCs and newly industrialized countries, creating special economic zones and export-processing zones (EK PSO-7.A.6). LDCs get jobs, but usually the lower-paying ones, which is why dependency theorists argue the global economy keeps them on the periphery.

Subsistence Agriculture and Commodity Chains (Unit 5)

Extensive practices like shifting cultivation and nomadic herding are concentrated in LDCs, while plantation agriculture in those same countries grows cash crops for export. One country can feed its villages with subsistence farming and feed foreign supermarkets through a global commodity chain at the same time.

Primate Cities and Urban Growth (Unit 6)

Many LDCs have a primate city, one giant city that dominates the whole country (think Lagos or Mexico City), instead of the even rank-size distribution common in developed countries. Rapid rural-to-urban migration in LDCs also fuels squatter settlements and strained infrastructure, a favorite SAQ data scenario.

Is Less Developed Countries on the AP Human Geography exam?

You almost never get asked 'define LDC.' Instead, the exam hands you data and expects you to recognize the development gap behind it. The 2022 SAQ gave a table of urbanization indicators (percent urban, urban growth rate, access to safe drinking water) and asked for comparisons across countries at different development levels. The 2021 SAQ used the Global Cities Index, where you had to notice that top-ranked world cities cluster in developed countries. The 2023 SAQ on staple food crops connected agricultural production to development levels in hearth countries.

In MCQs, expect stems like 'Which characteristic is most typical of a less developed country?' with answers testing measures from Topic 7.3 (high fertility, large primary sector, low literacy). In FRQs, you need to do three things with the term. First, identify LDCs from data tables or maps. Second, explain why a pattern exists (e.g., why LDCs have higher urban growth rates or larger informal sectors). Third, connect across units, like linking subsistence agriculture or primate cities back to development level.

Less Developed Countries vs Newly Industrialized Countries (NICs)

NICs are countries actively transitioning out of LDC status through rapid manufacturing growth, like Mexico, Brazil, or historically South Korea. The difference is trajectory. An LDC still has a dominant primary sector and low HDI, while a NIC has attracted outsourced factory jobs and is climbing the development ladder (EK PSO-7.A.5). On the exam, if a question mentions special economic zones, export-processing zones, or growing manufacturing employment, it's pointing at NICs, not the poorest LDCs.

Key things to remember about Less Developed Countries

• LDCs are defined by low scores on Topic 7.3 development measures, including GNI per capita, HDI, literacy rates, and access to health care, plus high fertility and infant mortality rates.

• LDCs typically have a large primary sector and informal economy, while developed countries have economies dominated by services.

• In world systems theory, LDCs are the periphery, supplying raw materials and low-wage labor to core countries through the international division of labor.

• In Unit 5, LDCs are where subsistence and extensive farming practices like shifting cultivation and nomadic herding are still common.

• In Unit 6, many LDCs feature primate cities and rapid urban population growth that outpaces infrastructure like safe drinking water and sanitation.

• Outsourcing and neoliberal trade policies have shifted manufacturing jobs from core countries into newly industrialized countries and some LDCs, creating special economic zones and export-processing zones.

Frequently asked questions about Less Developed Countries

What is a less developed country in AP Human Geography?

An LDC is a country with low industrialization, low standards of living, and a low Human Development Index score. It typically has a large agricultural sector, high fertility and infant mortality rates, low literacy, and limited access to health care.

Is 'less developed country' the same as 'periphery'?

Mostly yes. In Wallerstein's world systems theory, periphery countries are the least developed nations that export raw materials and cheap labor to the core. 'LDC,' 'developing country,' and 'periphery' overlap heavily on the AP exam, though 'periphery' specifically signals world systems theory.

How is an LDC different from a newly industrialized country (NIC)?

A NIC, like Mexico or Brazil, is in the middle of industrializing and has attracted outsourced manufacturing jobs, often in special economic zones. An LDC is still dominated by the primary sector with a low HDI. NICs are essentially LDCs that are successfully climbing toward developed status.

Do all LDCs have weak economies in every sector?

No. Many LDCs have booming export sectors, like plantation agriculture or mining, tied into global commodity chains. The catch is that profits often flow to core countries, and most domestic workers stay in low-paying primary-sector or informal jobs, which keeps overall development measures low.

Why do LDCs often have primate cities?

Economic opportunity in many LDCs concentrates in one dominant city, often a colonial-era port or capital, pulling massive rural-to-urban migration toward it. The result is a primate city like Lagos or Bangkok that is far larger than the country's second city, breaking the rank-size rule you learn in Topic 6.4.
