Gross Domestic Product (GDP) is one of the most widely used measures of development in IB Geography, but it has significant limitations. GDP measures the total value of goods and services produced within a country over a given period. While it provides a useful snapshot of economic activity, GDP alone does not accurately reflect human development or quality of life.

One major limitation of GDP is that it does not account for inequality. GDP per capita is an average figure, meaning it hides differences in income distribution within a country. A country may have a high GDP, but wealth may be concentrated among a small proportion of the population. As a result, many people may still experience poverty, poor housing, or limited access to healthcare and education despite strong economic output.

GDP also fails to measure quality of life and well-being. It does not consider health outcomes, education levels, life expectancy, or personal happiness. For example, a country may have a rapidly growing economy but high levels of stress, poor mental health, or limited work–life balance. In IB Geography, this highlights the difference between economic growth and true human development.

Another key limitation is that GDP ignores informal and unpaid work. Activities such as subsistence farming, childcare, and domestic labour contribute significantly to well-being but are not included in GDP calculations. This is particularly important in low-income countries, where large parts of the economy operate informally. As a result, GDP often underestimates economic activity and development in these regions.

GDP also does not reflect environmental sustainability. Economic growth may occur through resource depletion, pollution, or deforestation, all of which damage ecosystems and reduce future development potential. Environmental degradation can increase GDP in the short term while undermining long-term sustainability. In IB Geography, this limitation is crucial when linking development to climate change and resource security.

Another issue is that GDP can increase due to negative events. Natural disasters, conflict, or accidents may raise GDP through reconstruction and emergency spending, even though overall well-being declines. This makes GDP an unreliable indicator of progress or improvement in living conditions.

Because of these limitations, GDP is best used alongside other indicators. Composite measures such as the Human Development Index, as well as social indicators like life expectancy and literacy rates, provide a more balanced view of development. Qualitative measures can further enhance understanding of well-being.

Overall, while GDP is useful for comparing economic output, it is a poor standalone indicator of development. It fails to capture inequality, well-being, sustainability, and social progress.
