In the UN General Assembly resolution adopting the 2030 Agenda on 25 September 2015, SDG 1 reads: “End poverty in all its forms everywhere”, with target 1.1 stating: “By 2030, eradicate extreme poverty for all people everywhere, currently measured as people living on less than US$ 1.25 a day.” Yet, in early October 2015, the World Bank stated that the international extreme poverty line needed to be updated in order to take inflation into account and decided on its own that it was now US$ 1.90 a day (in 2011 Purchasing Power Parity). This raised protests from several countries, such as Brazil, who denied the right of a UN agency to change a decision endorsed after a deliberative process involving 193 Member States.
How was this International Poverty Line (IPL) designed? In 1990, three World Bank economists noted that six countries amongst the poorest were all within a poverty line of one US dollar per person. This similarity served as the basis of the original “US$ 1.00 a day” global poverty line, without any in-depth international research on the relevance and meaning of it. World Bank directors found this poverty line a very convenient tool to rank countries and adopted it. This decision is related to the twofold nature of the Bank, which is a research body comprising a lot of high level economists and also a bank that has clients, economic interests, and distributes loans and grants. In the design of the IPL, its simplicity and convenience for bankers have prevailed over the relevance for all other stakeholders. The good side of this decision is that the measurement of global extreme income poverty has attracted considerable interest over the last two decades and has perhaps helped to keep poverty high on the global agenda. The bad side it that is has reinforced a very technocratic and one-dimensional approach to poverty, when a multidimensional approach involving all stakeholders is needed.
The reliability of the World Bank global measure has long been challenged. The 2017 Atkinson report “Monitoring Global Poverty”, [fn]World Bank (2017).[/fn] that was commissioned by the former chief economist of the World Bank, recognizes minor sampling errors in the underlying household surveys and enumerates not less than fourteen sources of non-sampling errors that may make this measure of poverty and extreme poverty deeply flawed and unreliable. It recommends that the Bank adopt a “total error” approach and present formal estimates of statistical confidence of the numbers. World Bank representatives have recognized that this is one of the most important recommendations of the report. Yet they contend: “[…] we feel that we do not currently possess the in-house statistical capacity to correctly produce estimates of 'total error' arising from the multiplicity of possible sources of error listed above”. [fn]World Bank (2016).[/fn] This will not diminish the mistrust of people who scrutinize this approach.
Yet, besides these technical aspects, the IPL is subject to heavy criticism because of the very undemocratic way it has been defined. In ATD Fourth World’s long-lasting commitment to people trapped in extreme poverty all over the world, we never heard any of them define extreme poverty in their own words as living on less than US$ 1.00 or US$ 1.90 a day. Poverty and extreme poverty are hotly debated topics. Defining poverty without ever dialoguing with people who live in it would be comparable to writing about gender problems without ever talking to women.
This is why the International Movement ATD Fourth World and Oxford University have engaged in an international participatory research on the dimensions of poverty and how to measure them. National research teams comprising academics, practitioners and people living in poverty have been set up in six countries: Bangladesh, Bolivia, France, Great Britain, Tanzania and the USA. They will implement the Merging of Knowledge approach that we have been refining for 20 years; it enables people living in poverty to work as co-researchers on an equal footing with other participants.

The outcomes of this innovative and challenging project are expected in late 2019.
