Beyond GDP: The Flaws of Income Comparisons in Evaluating Poverty

India is one of the fastest-growing major economies in the world. Its GDP figures regularly make headlines, and policymakers cite them as proof of progress. But walk through rural Odisha, a tribal belt in Jharkhand, or an urban slum in Mumbai, and a very different story unfolds – one of persistent deprivation that no income statistic captures. This gap between what GDP tells us and what people actually experience sits at the heart of a critical question: can income comparisons ever be a reliable measure of poverty?

What income comparisons actually measure

GDP measures the total market value of all goods and services produced in a country within a given period. When divided by population, it gives us GDP per capita – a figure widely used to compare living standards across countries and over time. At first glance, this seems reasonable. But as economists at the IMF have pointed out, GDP was originally designed to measure wartime economic activity, not human welfare. Its architect, Simon Kuznets, himself flagged early on that national income statistics cannot serve as a measure of a nation’s wellbeing.

The problem is not just technical. It is conceptual. Two countries can have identical GDP per capita and yet offer their citizens radically different lived realities. One may have highly concentrated wealth, with a small elite pulling up the average, while the majority scrapes by. The other may have more evenly distributed income, with broad access to public services. As the International Growth Centre notes, GDP only addresses average income – it says nothing about who actually benefits from economic growth or how most people live.

The invisibility of non-market activities

One of the most significant distortions in income-based poverty measurement is what gets left out entirely. A large portion of economic life – especially in countries like India – takes place outside formal markets. Subsistence farming, barter, community mutual aid, and household production for self-consumption are all economically meaningful activities. Yet they generate no monetary transaction and therefore leave no trace in national income accounts.

Unpaid domestic and care work

Consider the labour of women in Indian households. Cooking, childcare, fetching water, caring for the elderly – this work is essential, constant, and economically productive. Yet it is entirely excluded from GDP. Research on unpaid work and GDP mismeasurement shows that routine housework and caregiving constitute the overwhelming share of unpaid labour globally, with strong gender gaps persisting across all income levels. In India, where women bear a disproportionate share of domestic responsibilities, this blind spot means the productive contribution of millions is simply not counted – and their economic situation appears worse than it is, or in the wrong ways, in official statistics.

The informal economy

India’s informal economy is not a marginal add-on – it is the backbone of how most people work and survive. Over 90% of India’s workforce is employed informally, in occupations ranging from street vending and home-based production to agricultural labour and small workshops. These workers lack written contracts, job security, or social protections, and their contributions are often poorly captured in official data. The informal sector accounts for roughly half of India’s GDP when agriculture is included – a figure confirmed by EU capacity development research – yet its internal dynamics, vulnerabilities, and welfare outcomes are largely invisible in income comparisons.

When income data from formal markets is used to judge poverty, the millions dependent on informal livelihoods appear either absent from the economic picture or artificially poorer. Either way, the measurement distorts the reality.

Market access is not equal

Income comparisons carry another hidden assumption: that all individuals participate in the market on roughly equal terms. In practice, they do not. Access to markets – whether for selling labour, buying goods, or accessing credit – is structured by caste, gender, geographic location, and social networks. A Dalit agricultural worker in Bihar and a software engineer in Bengaluru both show up in aggregate income data, but their relationship to the market is not remotely equivalent.

Research published in The Lancet Planetary Health has established that even the creator of GDP acknowledged it was never designed to capture welfare dimensions outside the economic domain – including health, safety, and social conditions. When markets systematically exclude or exploit certain groups, and when income figures are aggregated without accounting for this exclusion, the result is a metric that masks inequality rather than revealing it.

Rural-urban disparities illustrate this acutely in India. Rural populations tend to earn far less in monetary terms, face higher unemployment, and have weaker access to healthcare and education. Yet some of what appears as “low income” in rural settings reflects non-monetised self-sufficiency – growing one’s own food, using community resources – rather than deprivation in any meaningful sense. Income comparisons flatten this complexity entirely.

Perhaps the most damaging limitation of income-based measures is what economists call negative externalities – the social and environmental costs of economic activity that are not reflected in market prices and therefore not counted in GDP.

Environmental degradation as hidden poverty

When a factory pollutes a river, GDP records the factory’s output as a positive contribution to national income. It does not record the loss of livelihoods for fishing communities downstream, the rise in healthcare costs for people drinking contaminated water, or the long-term depletion of a shared ecological resource. As Earth.Org has documented, GDP structurally treats environmental damage as an externality – something outside the economic equation – which means the costs fall disproportionately on the poorest communities without appearing anywhere in income statistics.

In India, research published in the International Journal of Environmental Research and Public Health found that air pollution linked to economic activity was associated with 1.67 million deaths in 2019 alone, with the health burden concentrated in socially disadvantaged districts. These deaths, and the suffering behind them, do not subtract from GDP. If anything, spending on treating pollution-related illness adds to it. As Marshall Education’s analysis of GDP limitations explains, healthcare expenditure on pollution-related illness registers as economic output – not as evidence of societal harm.

Defensive expenditures: when spending on problems looks like progress

This connects to a broader flaw identified by economists like Joseph Stiglitz: GDP counts all spending as positive. Expenditure on security, crime prevention, disaster response, and environmental cleanup all inflate GDP, even though they represent society fixing problems rather than generating genuine welfare. A review of GDP alternatives in the journal Resources, Conservation and Recycling makes this point directly – GDP is not inherently wrong, but using it as a measure of overall well-being, as Stiglitz put it, is a form of dangerous misuse.

Alternative measures: moving beyond income

Recognition of GDP’s limits has driven the development of broader measures of development and poverty. The most widely used is the Human Development Index (HDI), developed by the UNDP, which combines income with life expectancy and educational attainment. According to UNDP data for India, the country’s HDI value in 2022 was 0.644, placing it 134th out of 193 countries – a markedly different picture from what GDP growth rates alone would suggest. Between 1990 and 2022, India’s GNI per capita grew by 287%, but its HDI grew by 48.4% – a gap that reflects how much human development lags behind raw income growth.

The Multidimensional Poverty Index (MPI) goes further, measuring deprivation across health, education, and living standards simultaneously. The Genuine Progress Indicator (GPI) adjusts consumption expenditure for inequality, environmental costs, and the value of unpaid work – effectively doing what GDP refuses to do. Analysis of India through a GPI lens suggests that GDP growth is actively masking issues of rising inequality, resource depletion, and social disparity that would otherwise demand urgent policy attention.

The UN Special Rapporteur on extreme poverty and human rights has been direct about the stakes. In a 2024 report to the UN Human Rights Council, Olivier De Schutter called GDP “a dangerous distraction” from what actually matters – people’s ability to live decent lives, which requires guaranteeing fundamental rights, valuing unpaid work, and measuring ecological wellbeing alongside income.

Why this matters for poverty policy

The stakes of using flawed metrics are not abstract. When poverty reduction policy is designed around income benchmarks, it tends to prioritise formal employment, GDP growth, and market integration as solutions. Communities that survive through non-market means, or who bear the environmental costs of growth in other regions, fall outside the frame. UNDP research tracking 160 countries post-2020 found that in nearly half of growing economies, extreme poverty actually increased alongside GDP growth – a finding that directly challenges the assumption that income growth translates into poverty reduction.

This divergence is not accidental. It is the predictable consequence of measuring an inherently multidimensional phenomenon – poverty – through a single, market-centric lens. Income comparisons capture what money can measure. They say nothing about whether a family has clean water, whether a child finishes school, whether a community’s forest is intact, or whether a woman’s twenty hours of daily labour is valued at all. Poverty, in its lived reality, spans all of these dimensions.

What do you think? If income figures systematically exclude the contributions of India’s 90% informal workforce and unpaid domestic labour, what would a truly accurate picture of development actually look like – and whose interests does the current measurement system serve? And given that GDP growth in many countries has run alongside rising poverty, should “economic growth” even remain the primary goal of development policy?
