Poverty & Inequality: The Economic Divide Explained

Main Ideas

Poverty and Inequality Are Related but Distinct

• Poverty concerns a lack of resources needed to maintain a basic standard of living. It is commonly assessed through income, but also through access to essentials such as food, health care, and shelter.
• Absolute poverty is measured against a fixed income threshold. The video cites the World Bank’s extreme-poverty line of $2.15 per person per day, adjusted for purchasing power parity (PPP).
• Relative poverty is measured against incomes in a particular society. The example given is the UK and EU threshold: household income, adjusted for household size, below 60% of median income.
• Inequality describes how income, wealth, or opportunities are distributed. A society can have little extreme poverty but still have high inequality if resources are concentrated among a small group.

In brief, poverty is about deprivation, while inequality is about the gap or disparity between people.

Global Poverty Trends and Setbacks

The video reports that the share of the global population in extreme poverty fell from about 36% in 1990 to around 9–10%, lifting more than a billion people out of extreme poverty over roughly three decades. Progress has varied by region:

• East Asia and the Pacific saw substantial reductions, supported by rapid economic growth, industrialisation, and welfare and social programmes.
• India, Bangladesh, and Pakistan also made progress, although deep rural poverty remains.
• Sub-Saharan Africa continues to have the highest extreme-poverty rates. The video cites nearly 40% of its population below the threshold in 2021.

The video notes that some country figures in its chart were dated and pre-pandemic. It cites particularly high rates in the Democratic Republic of the Congo, Mozambique, and Malawi.

COVID-19 reversed some progress: estimates cited suggest 70–100 million people were pushed back into extreme poverty. Reduced food affordability worsened hunger and malnutrition, while school closures affected more than 1.5 billion children. Unequal access to digital learning may have lasting effects on future incomes.

Subsequent inflation, external-debt pressures, higher interest costs, debt defaults, and geopolitical conflicts—including the Russia–Ukraine war—also slowed or reversed poverty reduction.

Multidimensional Poverty

Income alone does not capture all forms of poverty. A multidimensional approach considers overlapping disadvantages in areas such as health, education, and social inclusion.

Examples of indicators discussed include child mortality, malnutrition, years of schooling, access to electricity, clean drinking water, and sanitation.

The video gives examples from a 2024 multidimensional-poverty report: very high levels in Chad and South Sudan; around 16% in India; nearly half the population in Nigeria; and 24% in Ghana. It describes China and Brazil as having much smaller shares on this measure.

Measuring Inequality

The Gini coefficient is presented as the most widely used measure of income or wealth inequality:

• 0 represents perfect equality.
• 1, or 100 when indexed, represents extreme inequality.
• A score above 40 is described as very high inequality.

Another approach is to compare income shares across population groups—for example, the top 1% and bottom 10%. The Palma ratio compares the income share of the top 10% with that of the bottom 40%.

The video identifies South Africa and Namibia as having particularly high Gini scores in its 2023 comparison, with Brazil, Zambia, Mozambique, and Costa Rica also among the countries with high inequality.
