Context
The picture within Africa is more complex, and often obscured by problems with unreliable and non-comparable data, both over time and across countries. The most careful African data analysis suggests that, measured in monetary terms, African inequality is very high, Africa being the most unequal continent. There is, however, huge variation in the magnitude, changes and texture of this inequality across the continent.
This implies a double danger. Africa first needs to ensure that it is included in the international measurements. At least as importantly, the continent must also ensure that the particular contexts of its societies are considered in the analysis both of the factors causing inequality and the consequences of inequality. This analysis is absolutely crucial because it is the basis for policy interventions and civil society action, which are necessary to reverse the trend.
Given this context, a research project focusing on the development of diagnostic tools and capacity building was launched in partnership with the African Center of Excellence on Inequality Research (ACEIR) in the framework of the first phase of the Research Facility on Inequalities. The initial study (2018-2020) led to an in-depth analysis of inequalities in four countries: South Africa, Ghana, Kenya and Cote d’Ivoire. A Handbook on Inequality Measurement, which serves as a foundational guide for multidimensional inequality analysis, was also developed by ACEIR. The Handbook outlines key dimensions and indicators of inequality and provides guildelines for measuring income and beyond income inequalities.
This project was part of the first phase of the Research Facility on Inequalities, coordinated by AFD and funded by the European Commission's Directorate-General for International Partnerships over the 2017-2020 period. The first phase of the Facility has led to the conduct of 22 research projects and the publication of around 100 research papers and policy briefs.
Following the success of this research project:
- A fifth analysis was launched in Mozambique over the 2022-2024 period;
- A research project aming to expand and update the Handbook by incorporating methodologies for assessing vulnerabilities related to climate change and ecological transitions has also been launched over the 2024-2025 period.

Goals
The main objective of this research project was to advance the analysis of African inequality and the policy discussion on strategies to overcome inequality in Africa through a series of country-level engagements. The project was given structure and impetus through the development of a diagnostic tool that was implemented in a limited number of pilot countries. This diagnostic tool consists of a thorough analysis of the various inequalities in a given country which enables the government to identify the priorities and policy options in order to reduce them.
In order to build the diagnostic tool, a Handbook was also developed to set up a common base which enabled country comparisons. To extend its use and improve accountability, it was backed with a central data hub and strong data centres in each partner country that allowed and facilitated further inequality analysis.
Existing multidimensional inequality analyses primarily concentrate on examining inequalities within the social and economic domains. While many low-income countries are severely impacted by climate change, there is a notable research gap in the analysis of inequalities related to climate vulnerabilities and their interactions with other socio-economic and environmental factors. The extension and updating of the Handbook, carried out over the period 2024-2025, aims to address this gap and provide the guidelines for integrating the analysis of climate-related inequalities in future diagnostics.
Method
The diagnostic tool is based on three pillars :
- a conceptual and empirical review of the studies on inequality in Africa, allowing us to have a baseline for the development of future projects, as well as a better comprehension of the specificities of inequalities in Africa and of their measurement;
- a Handbook which contains the framework proposed for the country inequality diagnostics, the methodological issues around the measurement of inequalities and their analysis and the important issues linked to policies;
- the support to the implementation of the country diagnostic, in collaboration with the pilot countries’ local research teams and the creation of the data hub.
In order to expand and update the Handbook, researchers will thoroughly examine and synthesise existing literature that addresses the measurement and analysis of climate-related vulnerabilities. This approach will help identify gaps in current research and propose a minimal set of indicators for measuring vulnerabilities linked to climate change and the imperatives of the ecological transition and detail appropriate data and measurement methods to enable their inclusion as part of an inequality diagnostic report.
Results
In practical terms, the country diagnostic takes the form of a report which overviews the inequality within a country, across all relevant dimensions, for a given time and over time. Alongside this, it summarises the main policies passed, or in place, expected to have an impact on inequalities. Each country will use their diagnostic as a platform:
- for policy engagements on strategies to overcome inequality,
- for the stimulation of national dialogue and a national research focus on inequality,
- to lead the national discussion through further, high impact research papers from the country node on inequality.
- The Handbook on Inequality Measurements for Country Studies: in order to insure a certain degree of comparability among all the country studies and to support researchers and statisticians in conducting inequality diagnostics, a Handbook was developed by the African Centre of Excellence for Inequality Research (ACEIR).
- A review on inequality in Sub-Saharan Africa: this research paper takes stock of what we know about African inequality both to promote better analysis and better policymaking in addressing inequality in Africa.

Context
Between 2007 and 2013, the average annual growth rate of Burkina Faso’s gross domestic product (GDP) was approximately 7% per year in real terms, representing one of the best economic performances in West Africa. If we take into account the country’s strong population growth, the average rate of per-capita GDP rose by 3% per year during this same period. Meanwhile, the poverty rate grew from 45% in 1994 to 47% in 2009. Despite signs of a decline (40% in 2014), considerable inequalities remain.
This project is part of the first phase of the Research Facility on Inequalities, coordinated by AFD and funded by the European Commission's Directorate-General for International Partnerships over the 2017-2020 period. The first phase of the Facility has led to the conduct of 22 research projects and the publication of around 100 research papers and policy briefs.
Goal
The initial objective of this research program on inequalities in Burkina Faso is to create an inequality diagnostic in the country. In a second phase, scientific studies will be carried out on three themes:
- The dynamics of inequalities and of multidimensional poverty;
- Educational trajectories; and
- What happens to graduates of the educational system.
The objective here is to examine how school graduates become integrated into society later, and to what degree they put into practice the skills acquired at school.
The research will mainly concern the cities of Ouagadougou and Nouna, in western Burkina Faso.
Method
The diagnostic on inequalities will take stock of the situation in Burkina Faso through a literature review and analysis of data from national surveys. The dynamics of inequalities and of multidimensional poverty in Burkina Faso will be understood through the experiences of one of the partners of this project, the Ouagadougou and Nouna Observatories. Analysis of trends in inequalities and in multidimensional poverty over time will be carried out in urban, semi-urban, and rural areas, according to the demographic, social, and economic characteristics of households and to the degrees of poverty. Research on the educational trajectories and on what has become of people having graduated from the educational system will use the same data. The idea is to monitor cohorts of school graduates to study their trajectories and their integration into the society in the longer term.
Results
This research will give rise to conferences and workshops. Various publications are also planned: a report, policy briefs, and research articles.

Contexte
The inauguration of President Ramaphosa in February 2018 has offered the country an opportunity to put the South African project of Nelson Mandela back on track. But this will require confronting, head-on, the lack of progress towards a more balanced distribution of opportunities and incomes and the difficult political and economic questions that this raises. Will the benefits of political change be limited to a narrow elite or is more broad-based equitable development possible? What kinds of social, economic or institutional change might contribute to more rapid transformation of opportunities for the bottom half of the household income distribution? What kinds of constraints on power and privilege might contribute to fairer outcomes at the top tail of the distribution?
These difficult questions are of interest both in South Africa and internationally, and they are economic and institutional questions of considerable complexity. It is not just that a continued widening of inequality is unacceptable morally, it seems likely also that it threatens growth, social order and sustainability. Inequality reduction is under the spotlight in many countries and much work has been done internationally and in South Africa on understanding inequality.
This project is part of the first phase of the Research Facility on Inequalities, coordinated by AFD and funded by the European Commission's Directorate-General for International Partnerships over the 2017-2020 period. The first phase of the Facility has led to the conduct of 22 research projects and the publication of around 100 research papers and policy briefs.
Objectif
This project will draw on and consolidate this evidence-base and then fill some important, policy-relevant gaps that remain. By design, the research programme outlined below seeks to address distributional issues in both the bottom half and the top of the distribution. The work programme recognises from the outset that there are several dimensions of human development and wellbeing, and progress in some measures might be accompanied by deterioration in others. It recognises that economic growth does not necessarily lead to equitable outcomes – both poverty and inequality have self-reinforcing characteristics that are hard to counter.
The project will be undertaken in formal partnership with South Africa’s national statistical office, Statistics South Africa. Also, as important steps in the proposed research programme, a series of dialogues will be held between the researchers and key stakeholders, including representatives of government, business, organised labour and civil society – to seek advice, test ideas and contribute to consensus on possible policy reforms.
Méthode
The research project will be developed across three work streams:
- The implementation of the inequality diagnostic under the form of a report summarizing existing knowledge on South African inequality trends and policies. It will further add to this knowledge using available data, explore the implications of this new work and then take stock of data needs in order to make further progress in framing policies to overcome inequality.
- A paper on the role of earnings in the household inequality dynamics. It builds off preliminary evidence that a key aspect of the lack of support from the labour market into households is the volatility of employment and therefore earnings for the self-employed and other vulnerable workers.
- A paper on the interlinkages between population dynamics and spatial inequality. This paper is responsive to an often-expressed opinion from the policy community that migration is being driven by differences across provinces and regions in the quality of schooling, health, and other services.

Context
Reducing poverty and income inequalities has been one of the priorities of Senegalese governments since the end of the 1990s. While progress has been made, 23% of households surveyed in 2011 still considered themselves as very poor. To reduce these inequalities and promote growth that is beneficial to the poorest, it is crucial to develop the agricultural sector. There are various possible trajectories for doing so. One is intensification of agroecology, which seems to be good choice for this development, in particular for environmental reasons. For example, several projects have shown that agroecological practices enable productivity comparable to conventional agriculture while at the same time being much more friendly to the environment and the climate. However, there are have been few studies that have quantified the impact of these practices on farmer income and especially on income inequalities, despite the fact that this is a fundamental parameter for achieving the goals of eliminating severe poverty.
This project is part of the first phase of the Research Facility on Inequalities, coordinated by AFD and funded by the European Commission's Directorate-General for International Partnerships over the 2017-2020 period. The first phase of the Facility has led to the conduct of 22 research projects and the publication of around 100 research papers and policy briefs.
Goal
The objectives of this research project are to:
- quantify the current income inequalities in rural areas in Senegal;
- analyze what impact different types of public policies that promote agroecology would have on these inequalities.
It is therefore a question of determining the type of grant for Senegal’s agricultural sector that is most likely to reduce inequalities. Different types of inequalities are studied: by gender, within a single community, and between two communities located in different agroecological zones.
Method
This project uses a multidisciplinary approach which combines participatory workshops in rural areas and a stage of bio-economic modeling of outcomes during the workshops. To do so, outcomes, and models already used in international projects (e.g. AMMA-2050) are being expanded and improved. The analysis must also focus on a sector very largely neglected in the past: the combined systems of farming and or livestock raising. Two agroecological zones are being studied under two contrasting climates: one symbolizing the current climate and the other, defined by climatologists, representing the future climate. This will help assess the relevance of agroecology faced with climate change adaptation and to quantify its contribution to the resilience of vulnerable populations.

Context
According to the official Jordanian population census, there were an estimated 1.2 million Syrian refugees in the country as of November 2015. This figure corresponds to between 10% and 12% of the population. Approximately 660,000 of them are registered as “asylum seekers” by the UNHCR. But their number has been decreasing since 2015, probably because of migration, especially back to their home country.
The percentage of Syrian refugees who do not wish to live permanently in the three UN-run refugee camps in northern Jordan surpasses 90%. This is why they are settling in cities or the nearby rural areas, where they rent apartments and often live in unsuitable housing. Their main motivation for doing so is access to jobs.
This population influx to the cities has an impact on housing, services, activities, income, and the distribution of resources among urban residents. It can heighten the inequalities among the people living in Jordan, in particular between Jordanians and foreigners (1.7 million foreigners live in Jordan).
This project is part of the first phase of the Research Facility on Inequalities, coordinated by AFD and funded by the European Commission's Directorate-General for International Partnerships over the 2017-2020 period. The first phase of the Facility has led to the conduct of 22 research projects and the publication of around 100 research papers and policy briefs.
Objectives
The first part of the study focuses on the dynamics of economic inequality between households in Amman and Irbid, using the 2010 and 2016 Jordan Labor Market Panel Survey (JLMPS) and the 2013 and 2016 Household Expenditure and Income Survey (HEIS).
The second part of the study examines housing inequality among residents of Amman and Irbid. This section looks at both housing as a cost (household expenditures) and housing as a source of income (renting, selling, etc.).
Method
Many inequality indicators will be used: the Gini coefficient as well as the Atkinson index and the P90/P10 ratio, for example.
The data will come from:
- studies from 2010 and 2016 on the Jordanian labor market (Jordan Labor Market Panel Surveys);
- 2004 and 2015 population censuses (Jordanian Department of Statistics);
- data on household incomes and expenditures (Household Expenditure and Income Surveys, HEIS), 2013 and 2016;
- UNDP data on socio-economic inequalities in Jordan; and
- UNHCR data.
The research team is made up of two economists, one geographer, and one sociologist on the Jordanian side, and one economist and one urban planner on the AFD side.

Context
Since the end of apartheid, the successive South African governments have put emphasis on a very proactive public-housing policy, notably by having built 2.7 million housing units for the disadvantaged classes. However, various sources estimate that another 2 million affordable housing units are still needed (which would concern 12 million people, or one-fourth of the population of South Africa). Furthermore, construction of the 2.7 million housing units has not eliminated slums, which continue to spread in the major South African cities. Finally, most of the public housing has been established in the outer peripheries of cities: this hinders access by the beneficiaries to the areas offering jobs and services and contributes to continued racial and social segregation.
The most recent trends have seen the private sector encouraged to participate in the construction or renovation of affordable housing.
This project is part of the first phase of the Research Facility on Inequalities, coordinated by AFD and funded by the European Commission's Directorate-General for International Partnerships over the 2017-2020 period. The first phase of the Facility has led to the conduct of 22 research projects and the publication of around 100 research papers and policy briefs.
Goal
The objective of this research project is to understand the impact of projects such as the “Integrated Housing Developments” or so-called “social” housing in the major South African cities (Johannesburg, Cape Town, and Durban). Other tools furthering social inclusion are also studied, such as the regulations and tax incentives that encourage production of affordable housing by the private sector, etc.
As part of this study, we cover both the question of reducing economic inequalities and the question of the scale at which inequalities should be examined: by neighborhood, by district, or citywide.
The study also defines the determinants and obstacles with regard to the production of public and affordable housing. These include the economic model, support from the public sector, private investment, regulatory framework, difficulties in implementation, and others.
Method
The research project makes a case study of several projects involving the production of subsidized housing in three major South African cities (Cape Town, Johannesburg, and Durban). Several socio-economic indicators are used to evaluate inequalities.Series of data on housing supply and demand have been gathered, from the 2000s to 2018. The study looks for the most disaggregated data possible, in order to identify tendencies within cities regarding segregation, inclusion, and exclusion.
The role of different sources of income is analyzed, in particular the incomes and expenditures related to housing, by cross-analyzing them with the Gini index on inequalities.
The study also has a qualitative component dealing with the forms of production and regulation of affordable housing in South Africa.

Context
Reduction of inequality is one of the core Sustainable Development Goals (SDGs). One of the targets of SDG 10 is for income growth of a country’s poorest 40% to be higher than the national average. Reaching this objective requires setting up economic policies on public expenditures and taxes that will benefit the poorest people. At the same time, mobilizing tax revenue can play a key role in financing the SDGs, but it is important to understand under what conditions this higher level of tax revenue collection is reconcilable with the goal of reducing inequalities.
This project is part of the first phase of the Research Facility on Inequalities, coordinated by AFD and funded by the European Commission's Directorate-General for International Partnerships over the 2017-2020 period. The first phase of the Facility has led to the conduct of 22 research projects and the publication of around 100 research papers and policy briefs.
Goal
This research project seeks to improve understanding of the relationship between income inequality and budget policies in developing countries. The study is divided into three parts:
- Investigation into the redistributive impact of taxes, transfers, and public expenditure in three countries of West Africa (Côte d’Ivoire, Mali, and Senegal). The analysis will try to answer the following questions:
- Who pays taxes, and who benefits from the transfers and public expenditures?
-
What is the overall impact of the tax and transfer systems on inequalities?
-
What tax instrument can mobilize revenues while reducing poverty and inequality?
- Study of the effect on inequalities from applying different types of taxes in the developing countries. Is the increase in tax revenues (measured by the ratio between revenue and GDP) linked to a reduction or an increase in inequalities? The relationship between the type of taxes levied and the change in inequalities within a country and between different countries will be studied in order to identify which taxes are progressive or regressive.
- Analysis of tax compliance behaviors in Africa, by identifying how the level of inequalities affects citizens’ attitude towards taxes.
Method
This research project will use econometric quantitative studies based on household survey data and macro-economic data available on a large number of countries (Parts 2 and 3). Microsimulation tools will also be used (Part 1).

Context
Economic, social, and regional inequalities represent a major concern in Tunisia and around the world—for both ethical and political reasons. Growing gaps in equality threaten stability and social peace. They also discourage private initiative, curb investment, and reduce productivity.
This project is part of the first phase of the Research Facility on Inequalities, coordinated by AFD and funded by the European Commission's Directorate-General for International Partnerships over the 2017-2020 period. The first phase of the Facility has led to the conduct of 22 research projects and the publication of around 100 research papers and policy briefs.
Goal
This research project has two components.
- The first consists of an in-depth review of the state of inequalities in Tunisia, including the geographical dimension. It should help take stock of the knowledge about this issue in Tunisia, by highlighting the territorial aspects of the various dimensions of inequalities.
- The second component involves analysis of the determinants of inequalities. In a context of territorial comparison, the analysis focuses on social characteristics, training, and evolution of social capital. It also takes into account the importance of heritage in skills and knowledge, i.e. the inherited human capital that supplements the human capital acquired through the formal education system.
The two components of this research program are complementary and must be carried out in a parallel fashion. The objective? To give a broader perspective of the geographical aspects that characterize inequalities in Tunisia.
Two articles, available in the "Results" section below, have been produced from the research:
- The first one that takes stock of the inequalities;
- The second one on their determinants and on the role of human and social capital in the emergence (or formation) of inequalities.
Method
- A review of national and international literature will be conducted, especially on the conceptual and theoretical aspects. This will make it possible to fine-tune the analytical framework for measurement and analysis of inequalities and their determinants.
- A quantitative analysis on the state and evolution of inequalities will be carried out, based on available data.
- A survey will be carried out, with the main objective of gathering data on human capital and on social capital, through the diverse geographical areas of Tunisia where quite homogeneous communities are identified. This survey will make it possible to propose a measurement of human and social capital, which will be used to analyze the determinants of inequalities.
