Abstract
In many countries, large differences in poverty persist at the subnational level. In addition, global challenges such as climate change, fragility, economic crises, and food insecurity are often trans-border issues that pose significant risks for poverty reduction both across and within countries. Traditional poverty measures are generally presented at the national level, potentially obscuring local and regional variations of poverty and inequality. To overcome these challenges, this note describes the construction of two databases designed to provide a more granular perspective on poverty. The Subnational Poverty and Inequality Database (SPID) presents direct survey estimates of poverty and inequality from nationally representative household surveys over time. The Global Subnational Atlas of Poverty (GSAP) presents poverty estimates of survey-representative administrative areas projected to a common year. Both databases use the same underlying household survey data used by the World Bank to monitor global poverty.

Publication March 2021 Update to the Global Database of Shared Prosperity(World Bank, Washington, DC, 2021-03)Shared prosperity is the World Bank’s second Twin Goal, introduced in 2013. It is defined as the growth in household per capita income or consumption of the poorest 40 percent of the population. The Global Database of Shared Prosperity (GDSP) is the database that is used to monitor progress of this indicator. The March 2021 update introduces the 8th edition of the Global Database of Shared Prosperity. This note documents the data availability in this edition and the main differences with the 7th edition.Publication October 2022 Update to the Global Database of Shared Prosperity(World Bank, Washington, DC, 2022-10)The October 2022 update introduces the 10th edition of the Global Database of Shared Prosperity (GDSP). Shared prosperity, defined as the growth in per capita household income or consumption of the poorest 40 percent of the population, is the World Bank’s second Twin Goal, alongside ending extreme poverty. The new edition of the GDSP revises the figures released in April 2022 to the 2017 PPPs and includes estimates for India. Indicator coverage is also revised to include 81 of the world’s economies in 2019. This technical note describes the GDSP, documents the available data in this edition, and highlights the main differences with the 9th edition.Publication October 2022 Update to the Multidimensional Poverty Measure(World Bank, Washington, DC, 2022-10)The World Bank’s Multidimensional Poverty Measure (MPM) presents a broader understanding of poverty beyond just the monetary dimension by incorporating access to education and basic infrastructure as additional dimension of well-being. It aims to thus highlight additional deprivations experienced by poor households beyond the monetary headcount ratio at the 2.15 dollars international poverty line. To estimate the MPM in a standard way for as many countries as possible, data limitations result in a trade-off between the number of dimensions that can be included and the number of countries that have the required harmonized indicators. Both education and access to basic infrastructure are generally available in household surveys across the world. The World Bank’s measure takes inspiration and guidance from other prominent multidimensional measures, particularly the Multidimensional Poverty Index (MPI) developed by UNDP and Oxford University. The MPM and MPI differ in one important aspect: the MPM includes the monetary poverty dimension, measured as having household income or consumption per capita that is less than 2.15 dollars per day, the new International Poverty Line at 2017 PPPs published by the World Bank in 2022. A focus on non-monetary deprivations for the income-poor highlights to policymakers the importance of improving other aspects of human welfare that may not be well-captured by the monetary measure alone. For example, households that are income poor as well as deprived in non-monetary dimensions face worse levels of well-being than households that are only income poor but have good access to services and education. It is also useful to measure deprivations in basic services faced by non-income-poor households, including households that leave extreme poverty but continue to experience nonmonetary deprivations, as these households face different constraints to well-being. A poverty measure that includes nonmonetary aspects thus highlights deprivations that may otherwise remain hidden. Securing higher living standards for a population becomes more challenging when poverty in all its forms is considered, but it can provide policymakers a roadmap for and a means of monitoring improvements in welfare.Publication Does Hotter Temperature Increase Poverty and Inequality?(World Bank, Washington, DC, 2023-06-24)Despite a vast literature documenting the harmful effects of climate change on various socio-economic outcomes, little evidence exists on the global impacts of hotter temperature on poverty and inequality. Analysis of a new global panel dataset of subnational poverty in 134 countries finds that a one-degree Celsius increase in temperature leads to a 9.1 percent increase in poverty, using the US$1.90 daily poverty threshold. A similar increase in temperature causes a 0.8 percent increase in the Gini inequality index. The paper also finds negative effects of colder temperature on poverty and inequality. Yet, while poorer countries—particularly those in South Asia and Sub-Saharan Africa—are more affected by climate change, household adaptation could have mitigated some adverse effects in the long run. The findings provide relevant and timely inputs for the global fight against climate change as well as the current policy debate on the responsibilities of richer countries versus poorer countries.Publication April 2024 Update to the Global Database of Shared Prosperity(Washington, DC: World Bank, 2024-08-09)This note introduces the 13th edition of the Global Database of Shared Prosperity (GDSP). Shared prosperity is the growth in per capita household income or consumption of the poorest 40 percent of the population. This edition of the GDSP revises figures released in November 2024 with the latest data available for 88 economies for circa 2016-2021, including data on fourteen new countries. This note describes the GDSP, documents the available data, and highlights the main differences with the 12th edition.

Publication Doing Business 2014 : Understanding Regulations for Small and Medium-Size Enterprises(Washington, DC: World Bank Group, 2013-10-28)Eleventh in a series of annual reports comparing business regulation in 185 economies, Doing Business 2014 measures regulations affecting 11 areas of everyday business activity: Starting a business, Dealing with construction permits, Getting electricity, Registering property, Getting credit, Protecting investors, Paying taxes, Trading across borders, Enforcing contracts, Closing a business, Employing workers. The report updates all indicators as of June 1, 2013, ranks economies on their overall “ease of doing business”, and analyzes reforms to business regulation – identifying which economies are strengthening their business environment the most. The Doing Business reports illustrate how reforms in business regulations are being used to analyze economic outcomes for domestic entrepreneurs and for the wider economy. Doing Business is a flagship product by the World Bank and IFC that garners worldwide attention on regulatory barriers to entrepreneurship. More than 60 economies use the Doing Business indicators to shape reform agendas and monitor improvements on the ground. In addition, the Doing Business data has generated over 870 articles in peer-reviewed academic journals since its inception.Publication World Development Report 2011(World Bank, 2011)The 2011 World development report looks across disciplines and experiences drawn from around the world to offer some ideas and practical recommendations on how to move beyond conflict and fragility and secure development. The key messages are important for all countries-low, middle, and high income-as well as for regional and global institutions: first, institutional legitimacy is the key to stability. When state institutions do not adequately protect citizens, guard against corruption, or provide access to justice; when markets do not provide job opportunities; or when communities have lost social cohesion-the likelihood of violent conflict increases. Second, investing in citizen security, justice, and jobs is essential to reducing violence. But there are major structural gaps in our collective capabilities to support these areas. Third, confronting this challenge effectively means that institutions need to change. International agencies and partners from other countries must adapt procedures so they can respond with agility and speed, a longer-term perspective, and greater staying power. Fourth, need to adopt a layered approach. Some problems can be addressed at the country level, but others need to be addressed at a regional level, such as developing markets that integrate insecure areas and pooling resources for building capacity Fifth, in adopting these approaches, need to be aware that the global landscape is changing. Regional institutions and middle income countries are playing a larger role. This means should pay more attention to south-south and south-north exchanges, and to the recent transition experiences of middle income countries.Publication World Development Report 2006(Washington, DC, 2005)This year’s Word Development Report (WDR), the twenty-eighth, looks at the role of equity in the development process. It defines equity in terms of two basic principles. The first is equal opportunities: that a person’s chances in life should be determined by his or her talents and efforts, rather than by pre-determined circumstances such as race, gender, social or family background. The second principle is the avoidance of extreme deprivation in outcomes, particularly in health, education and consumption levels. This principle thus includes the objective of poverty reduction. The report’s main message is that, in the long run, the pursuit of equity and the pursuit of economic prosperity are complementary. In addition to detailed chapters exploring these and related issues, the Report contains selected data from the World Development Indicators 2005‹an appendix of economic and social data for over 200 countries. This Report offers practical insights for policymakers, executives, scholars, and all those with an interest in economic development.Publication Classroom Assessment to Support Foundational Literacy(Washington, DC: World Bank, 2025-03-21)This document focuses primarily on how classroom assessment activities can measure students’ literacy skills as they progress along a learning trajectory towards reading fluently and with comprehension by the end of primary school grades. The document addresses considerations regarding the design and implementation of early grade reading classroom assessment, provides examples of assessment activities from a variety of countries and contexts, and discusses the importance of incorporating classroom assessment practices into teacher training and professional development opportunities for teachers. The structure of the document is as follows. The first section presents definitions and addresses basic questions on classroom assessment. Section 2 covers the intersection between assessment and early grade reading by discussing how learning assessment can measure early grade reading skills following the reading learning trajectory. Section 3 compares some of the most common early grade literacy assessment tools with respect to the early grade reading skills and developmental phases. Section 4 of the document addresses teacher training considerations in developing, scoring, and using early grade reading assessment. Additional issues in assessing reading skills in the classroom and using assessment results to improve teaching and learning are reviewed in section 5. Throughout the document, country cases are presented to demonstrate how assessment activities can be implemented in the classroom in different contexts.Publication Remarks to the Annual Meetings 2020 Development Committee(World Bank, Washington, DC, 2020-10-16)David Malpass, President of the World Bank Group, announced that the Board approved a fast track approach to emergency health support programs that now covers 111 countries. Most projects are well advanced, with average disbursement upward of 40 percent. The goal is to take broad, fast action early. The operational framework presented back in June has positioned the Bank to help countries address immediate health threats and social and economic impacts and maintain our focus on long-term development. The Bank is making good progress toward the 15-month target of 160 billion dollars in surge financing. Much of it is for the poorest countries and will take the form of grants or low-rate, long-maturity loans. IFC, through the Global Health Platform, will be providing financing to vaccine manufacturers to foster expanded production of COVID-19 vaccines in both part 1 and 2 countries, providing production is reserved for emerging markets. The Development Committee holds a unique place in the international architecture. It is the only global forum in which the Governments of developed countries and the Governments of developing countries, creditor countries and borrower countries, come together to discuss development and the ‘net transfer of resources to developing countries.’ The current International Financial Architecture system is skewed in favor of the rich and creditor countries. It is important that all voices are heard, so Malpass urged the Ministers of developing countries to use their voice and speak their minds today. Malpass urged consideration of how we can build a new approach to debt restructuring that allows for a fair relationship and balance between creditors and debtors. This will be critical in restoring growth in developing countries; and helping reverse the inequality.
