An accurate definition of poverty is crucial to help organisations and governments understand which citizens and communities are most in need. Understanding what poverty is also helps us identify new and growing problems in our increasingly complex societies, such as social exclusion, mental health, violence or drug abuse.
About the Poverties Project

This article is part of what was originally the 'Poverties project' which we ran from 2011-2016. It aimed to make social and economic research on poverty accessible to everyone. It focused on presenting evidence-based causes and solutions as much as possible, although with a pinch of sarcasm, cynicism or dark humour at times. Hopefully, it helps make the description of certain (horrible) situations more bearable.

EDIT: We have launched our first-ever children's book on the Sustainable Development Goals. A pretty unique way to educate both kids and parents on the best ways to care for the human and natural worlds!

The definition of poverty, according to Encyclopedia Britannica (2008):

“The state of one who lacks a usual or socially acceptable amount of money or material possessions. […] Whatever definition one uses, authorities and laypersons alike commonly assume that the effects of poverty are harmful to both individuals and society."

Over 200 years ago, Adam Smith (father of modern economics) saw in impoverishment not just a lack of access to the basic necessities to maintain a decent life, but also a social handicap. In that sense, poverty is about being an active member of society, taking part in the social, economic and cultural life of your country.

Poverty as a social handicap

Social exclusion, or marginalization, thus becomes a key aspect to get a real grasp of what poverty is. In many cases indeed, if you don’t have the right, decent clothes or suit, you’re very unlikely to be offered a job and your situation will only get worse. Anything from the "right" haircut (i.e. culturally accepted), shoes or behaviour can affect your situation. That's why suffering of a mental illness, however temporary, is often crippling in the long term.

That's why coming up with a universal definition of poverty is quite impossible as it’s an issue that depends on social norms. Secondly, the question of defining poverty is deeply interwoven with the problem of measuring poverty (using poverty lines or statistics).

But measuring poverty where? In what context? Surely, inner-city poverty is radically different than rural poverty. And yet you're about to find out that governments often don't see any difference between the two. Usually, on purpose.

Poverty as lack of economic development

A definition of poverty by its solution

If economic development used to be associated with growth, it is now the spearhead of the war on poverty. Therefore, thinking about what poverty means nowadays is becoming intimately linked to pathways to help poorer countries to develop their economy.

That’s also the reason why the World Bank is now a self-proclaimed world fighter against poverty, with its slogan: “Our dream is a world free of poverty”. The UN as well has its own program aimed at reducing “by half, between 1990 and 2015, the proportion of people whose income is less than $1 a day”: the Millennium Development Goals (now replaced by the Sustainable Development Goals). Let’s observe then the relationship between extreme poverty and economic development - especially in a context of neoliberal globalization.

Poor capital, labor and infrastructure

The general assumption is that the causes of poverty are rooted in a nation’s weak forces of production, capital, labor etc. The definition of poverty is then characterized by a general lack of infrastructure, institution, technology and education.

But these people forget that economic growth alone is not enough. There is plenty of examples out there of insanely rich countries with insanely high levels of poverty. This is because poverty also stems from flaws in the redistribution of a country’s wealth.

The 1% vs. the 99% ?

If the capital owners keep all the revenues to themselves and don’t raise salaries, then nothing changes except that 1% of the population gets rich as hell. So what matters here is to look at the mean of growth, to make sure that everyone participates in a country's growth and benefits from it.

This makes the measurement of poverty an even more central and complex issue: you can’t just look at a country’s GDP anymore. If a government is serious about improving its measurement and definition of poverty, it should use a diversity of research tools - quantitative and qualitative (such as field interviews) - so as to get a real grasp of what poverty is like in its country.

What is poverty: science vs politics

What is the impact of urban poverty
‍The social damage of urban poverty

Cost of life and food

The scientific tradition that sets poverty lines usually focuses on the cost of life and especially on food. The reason is that the poorest of the poor (i.e. in poor countries) spend on average up to 75% of their budget on food. The problem is that, as you’ve seen so far, poverty is a very blurry and “elastic” notion.

The needs of the poor in Burundi are entirely different than that of the ones in Mexico which are also somewhat unrelated to that of Northern Americans. To some extent.

Food or Internet?

Those needs range from food, indeed, but also clothing (think about Russia’s poor), proper shelter (protection from snow or tropical storms), but also goods that are necessary to one’s participation in social life (remember, exclusion is also poverty): radio, TV, Internet.

In many countries, several social services are now only available online. No computer? no Internet? Say goodbye to social benefits, higher education and so on. Still… You can rightfully argue that you won’t die out of lack of Internet. Even if more and more people seem to think so.

How much food is enough?

The result however is that too many countries keep on setting their national poverty lines along with the cost of the necessary amount of food needed per day. How do they calculate that? The international scientific norm is that an adult needs some 2,000 calories a day. But even this line is somewhat wrong since it totally disregards the importance of a varied nutrition and the different cost of eating fish, fruits and vegetables in opposition to simple wheat or cereal intake.

The lack of particular vitamins or minerals itself leads to countless diseases regarded as effects of poverty. Unfortunately politics too often come into play to meddle in the definition of what poverty is. If governments were to take into account a diverse nutrition as well as essential goods, their number of people estimated to live under the poverty line would literally shoot up quite a bit. This is true even in richer countries, but much worse in poorer ones.

The limits of the poverty line

Poverty lines are useful to compare poverty from country to country and get a general picture of the problem at the global level. The problem with  is however that their computing is widely contested by experts, who complain about the same political manipulations I've just talked about.

The biggest issue with any poverty line such as the $1.25-a-day one is that anybody living with less than $1.25 a day is indeed considered poor, but those earning $1.30 or $1.45 per day are not counted as poor. There are millions and millions of them and they are considered safe from precariousness. In that case, the most accurate poverty line ever would still be an inappropriate measure to understand what poverty is.

Relative or absolute poverty?

What are relative and absolute poverty?

What is poverty, but a form of exclusion

Amartya Sen, one of the most famous researchers on the topic, has given a more appropriate definition of poverty that completes Adam Smith’s approach. He defined poverty as the lack of what one needs to live within a society. In the broadest sense, it means survival but also contribution and participation to social daily activities.

You may have enough food or water but not the proper environment or education (hygiene) that will let you enjoy it. Diarrhea for example is a major cause of child death: 1.5 million per year . You may have enough money to buy a computer but not the required infrastructure to have the Internet in your neighborhood or even the electricity.

It's all about relative vs absolute poverty

Luckily and because this definition of poverty is already a few decades old, the biggest international institutions started paying more attention to the varied nature of poverty.

The United Nation’s Human Development Index is a good example since it's calculated with three values: income, life expectancy and literacy. This helps us think about the issue in terms of relative poverty as opposed to absolute poverty, i.e. the total absence of the most basic needs (food, shelter, water…).

Other types of poverty

Institutional poverty

This is when the government is unable to get its citizens and private companies to pay their taxes. This creates a poverty cycle whereby national institutions constantly lack money. Public servants are then underpaid, the most qualified ones try to get a job elsewhere and the rest do not have much motivation to do their job either. This is a great incentive to indulge in corruption...

The national and local authorities are in turn unable to maintain in good state or expand basic infrastructures such as water pipes, as well as provide basic services like education or health care. Finally the sum of all this makes the government powerless when facing issues of regulating, promoting, or expanding sectors that would need basic infrastructure investment.

This whole aspect makes the private sector at large turn away from regular, official ways of doing business. An informal sector often thrives on conditions like this and businesses find their own way to get things done… which means a lot more corruption and no control over the risk of monopolies or even violence.

Individual poverty

Non-existent legal employment means more risks and fewer rights for average workers. Usually they won’t be covered for work-related accidents, no health care or pension plan, no contract (possibility to be sacked at any time), no protection against any abuse at work: harassment, violence, unpaid overtime or simple exploitation.

A good deal of individual poverty stems directly from consequences of institutional poverty, such as the lack of access to the basic services mentioned above. Lack of education fosters more poverty and impossibility to climb up the social ladder; restricted access to health care causes diseases to spread wildly across the population. An unintended result is a dangerous lack of confidence in the government… a crisis of legitimacy for this one.

In order to survive people have to rely on their wit and catch-as-catch-can skills, which can definitely reinforce bonds within a community, but on a bigger scale it also nurtures an environment where everyone tries to take advantage of one another… and loses confidence in each other. This shows that poverty can also be boiled down to an institutional failure, as most of individual poverty stem from from a system's dysfunction.

Or as someone put it once:

"Overcoming poverty is not a task of charity, it is an act of justice. Like slavery and apartheid, poverty is not natural. It is man-made and it can be overcome and eradicated by the actions of human beings." (Nelson Mandela)

What is urban poverty?

what is poverty in cities
Why a definition for urban areas?

Urbanization is generally viewed as an essential factor in reducing poverty and mostly developing an economy. All over the world cities are growing and more and more people live in urban areas. Economic theories argue that this shift in world populations will, as a consequence, help develop rural areas.

Incompetence and lack of city planning

While this might be true, another problem is also occurring: the growth of urban poverty, in many cases for the plain reason that city planners have not been… planning, not well enough at least. And in most cases not enough accommodation was built for the few millions trying to live in town, and no one either managed to create enough jobs for everybody. However, if in some cases there have been economic opportunities for the newcomers, the stacking up of people in slums is a geographical catastrophe in itself and an extremely effective way to spread diseases and crime.

Are we any closer to understanding what poverty is now? From that angle it's the crystallization of political incompetence and disregard for a population's needs. On top of that, for the poorest of them, urban dwellers can’t even go back to their rural hometowns because they can’t even afford it anymore. Yet this phenomenon is still fairly recent, and it's crucial that organisations around the world start gathering solid research to better understand urban poverty.

No one meaning of poverty?

This page should have given you a pretty broad answer to the question of poverty -with many links to key articles to deepen your understanding of it - by introducing the definition of poverty in absolute vs. relative terms and the more recent approach of it as an economic and developmental issue.

And it should have also helped you keep in mind that growth-obsessed policies are not always good for the poor - if they're not included in the process anywhere, they can’t benefit from it.

Using safety nets and subsidies

A growth-focused approach should be complemented with systems promoting the fair redistribution of the wealth created.

For instance, safety nets to fight social exclusion and destitution, private sector subsidies (in particular SMEs) and channeling private investments in the right sectors to boost local jobs where they're needed. 

In other words, make market competition work for everybody, be it to provide electricity to every community or to expand the telecommunications network to unserved and not yet profitable populations.

This is all the more important as developing countries often come out weakened by the recent waves of privatization and liberalization of their economies led by the WTO (World Trade Organization) and the World Bank. Counter-balancing those worsening effects is one of the main challenges of policymakers worldwide.

So... what is poverty if indeed a key economic and social development problem? Our civilizations have evolved into more and more complex societies and systems which only a few really understand. 

But problems such as lack of political will and poor management of resources have remained unsolved throughout History and political regimes. They create pose a real threat to stable and peaceful societies when people find no other way to be heard than by using violence to demand a fairer redistribution of resources.
