Abstract
The middle class in Latin America and the Caribbean has been a central focus of policy debates in the region since the COVID-19 pandemic began. To identify and track vulnerable and middle-class populations accurately, it is necessary to update the upper and lower bounds for the middle class using 2017 purchasing power parity exchange rates. This paper contributes with a two-step methodology for updating these thresholds. The method indicates that updating the $13 lower-bound line in 2011 purchasing power parity dollars to 2017 purchasing power parity dollars results in a vulnerability line of $14. The study also finds an upper bound of $81 per person per day in 2017 purchasing power parity, compared with $70 in 2011 purchasing power parity. These thresholds are robust to a variety of assumptions and methodologies. The results of this study indicate that the proportion of the population in Latin America and the Caribbean classified as middle class increased from 36.3 percent in 2011 to 37.2 percent in 2017. However, there were no significant changes in the characteristics of this group.

Publication March 2024 Update to the Poverty and Inequality Platform (PIP)(Washington, DC: World Bank, 2024-04-01)The March 2024 update to the Poverty and Inequality Platform (PIP) involves several changes to the data underlying the global poverty estimates. In particular, some welfare aggregates have been revised, and the CPI, national accounts, and population input data have been updated. This document explains these changes in detail and the reasoning behind them. Moreover, 101 new country-years have been added, bringing the total number of surveys to more than 2,300. Depending on the availability of recent survey data, global and regional poverty estimates are reported up to 2022. This is the first time PIP is reporting global poverty estimates post-2019, covering the period of the COVID-19 pandemic.Publication Reconstructing 2010–2022 Poverty and Inequality Trends in Bangladesh(Washington, DC: World Bank, 2024-04-05)The 2022 Household Income and Expenditure Survey enhances fieldwork, data management, and information quality but poses comparability challenges with previous rounds. This study proposes a two-step process based on statistical matching to fill the information gap in previous survey rounds. This methodology uses the more comprehensive 2022 information to reconstruct comparable consumption measures over time. This allows for a consistent assessment of poverty and inequality measures, providing insights into the changes for policy makers, researchers, and stakeholders over the years. The results reveal that integrating this correction into previous survey rounds would have reduced poverty rates by around 10.6 percentage points between 2010 and 2016 and a further decrease of 7.8 percentage points between 2016 and 2022. Likewise, extreme poverty rates would have witnessed a decline of approximately 3 percentage points in the earlier period and a more substantial drop of 3.6 percentage points in the more recent one. These poverty reduction trends mirror improvements in other dimensions of well-being, like reductions in infant mortality and stunting and increases in access to electricity, sanitary toilets, and literacy rates.Publication Is There Such Thing As Middle Class Values? Class Differences, Values and Political Orientations in Latin America(2011-11-01)Middle class values have long been perceived as drivers of social cohesion and growth. This paper investigates the relation between class (measured by position in the income distribution), values, and political orientations using comparable values surveys for six Latin American countries. The analysis finds that both a continuous measure of income and categorical measures of income-based class are robustly associated with values. Both income and class tend to display a similar association to values and political orientations as education, although differences persist in some important dimensions. Overall, there is no strong evidence of any "middle class particularism": values appear to gradually shift with income, and middle class values are between the ones of poorer and richer classes. If any, the only peculiarity of middle class values is moderation. The analysis also finds changes in values across countries to be of much larger magnitude than the ones dictated by income, education, and individual characteristics, suggesting that individual values vary primarily within bounds dictated by each society.Publication Economic Mobility and the Rise of the Latin American Middle Class(Washington, DC: World Bank, 2013)After decades of stagnation, the size of Latin America's middle class recently expanded to the point where, for the first time ever, the number of people in poverty is equal to the size of the middle class. This volume investigates the nature, determinants and possible consequences of this remarkable process of social transformation. We propose an original definition of the middle class, tailor-made for Latin America, centered on the concept of economic security and thus a low probability of falling into poverty. Given our definition of the middle class, there are four, not three, classes in Latin America. Sandwiched between the poor and the middle class there lies a large group of people who appear to make ends meet well enough, but do not enjoy the economic security that would be required for membership of the middle class. We call this group the 'vulnerable'. In an almost mechanical sense, these transformations in Latin America reflect both economic growth and declining inequality in over the period. We adopt a measure of mobility that decomposes the 'gainers' and 'losers' in society by social class of each household. The continent has experienced a large amount of churning over the last 15 years, at least 43% of all Latin Americans changed social classes between the mid 1990s and the end of the 2000s. Despite the upward mobility trend, intergenerational mobility, a better proxy for inequality of opportunity, remains stagnant. Educational achievement and attainment remain to be strongly dependent upon parental education levels. Despite the recent growth in pro-poor programs, the middle class has benefited disproportionally from social security transfers and are increasingly opting out from government services. Central to the region's prospects of continued progress will be its ability to harness the new middle class into a new, more inclusive social contract, where the better-off pay their fair share of taxes, and demand improved public services.Publication The Gradual Rise and Rapid Decline of the Middle Class in Latin America and the Caribbean(World Bank, Washington, DC, 2021-05-20)Latin America and the Caribbean (LAC) reported over 30 million Coronavirus (COVID-19) cases and around 960,000 deaths as of May 2021. Official tracking data shows that Brazil, Colombia, and Argentina have the highest number of reported cases throughout LAC, which in turn is the region with among the highest numbers across all developing regions. Moreover, Brazil is the third-worst affected country worldwide, after the United States and India, with approximately 15.4 million infections. Dramatic declines in economic activity are expected throughout the LAC region due to the global pandemic. Unfortunately, many LAC countries entered the crisis with low potential economic growth and high levels of inequality, following the region’s recent period of stagnant growth. The 2020 COVID-19 crisis will likely reverse in a short time frame many of the social gains that took decades to materialize in Latin America and the Caribbean. In the past two decades, the region has seen a reduction in the number of people living in poverty by nearly half and an increase in the size of its middle class. Income inequality also decreased, as income growth has been primarily pro-poor in recent years. Despite variations across countries, most have experienced positive welfare gains since the early 2000s. However, the growth deceleration of 2014–2019 coupled with the dramatic fall in activity caused by the COVID-19 crisis will negatively impact living standards and well-being across the region. Poverty projections for 2020 suggest that the number of the poor increased in most LAC countries. Brazil, however, implemented a generous emergency transfer program that benefited almost 67 million people and lifted millions out of poverty. As a result, poverty in the LAC region is expected to decline marginally from 22 percent in 2019 to 21.8 percent in 2020. Had no mitigation measures been implemented, the region may instead have seen 28 million new poor in 2020.

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 2024(Washington, DC: World Bank, 2024-08-01)Middle-income countries are in a race against time. Many of them have done well since the 1990s to escape low-income levels and eradicate extreme poverty, leading to the perception that the last three decades have been great for development. But the ambition of the more than 100 economies with incomes per capita between US$1,100 and US$14,000 is to reach high-income status within the next generation. When assessed against this goal, their record is discouraging. Since the 1970s, income per capita in the median middle-income country has stagnated at less than a tenth of the US level. With aging populations, growing protectionism, and escalating pressures to speed up the energy transition, today’s middle-income economies face ever more daunting odds. To become advanced economies despite the growing headwinds, they will have to make miracles. Drawing on the development experience and advances in economic analysis since the 1950s, World Development Report 2024 identifies pathways for developing economies to avoid the “middle-income trap.” It points to the need for not one but two transitions for those at the middle-income level: the first from investment to infusion and the second from infusion to innovation. Governments in lower-middle-income countries must drop the habit of repeating the same investment-driven strategies and work instead to infuse modern technologies and successful business processes from around the world into their economies. This requires reshaping large swaths of those economies into globally competitive suppliers of goods and services. Upper-middle-income countries that have mastered infusion can accelerate the shift to innovation—not just borrowing ideas from the global frontiers of technology but also beginning to push the frontiers outward. This requires restructuring enterprise, work, and energy use once again, with an even greater emphasis on economic freedom, social mobility, and political contestability. Neither transition is automatic. The handful of economies that made speedy transitions from middle- to high-income status have encouraged enterprise by disciplining powerful incumbents, developed talent by rewarding merit, and capitalized on crises to alter policies and institutions that no longer suit the purposes they were once designed to serve. Today’s middle-income countries will have to do the same.Publication Argentina Country Climate and Development Report(World Bank, Washington, DC, 2022-11)The Argentina Country Climate and Development Report (CCDR) explores opportunities and identifies trade-offs for aligning Argentina’s growth and poverty reduction policies with its commitments on, and its ability to withstand, climate change. It assesses how the country can: reduce its vulnerability to climate shocks through targeted public and private investments and adequation of social protection. The report also shows how Argentina can seize the benefits of a global decarbonization path to sustain a more robust economic growth through further development of Argentina’s potential for renewable energy, energy efficiency actions, the lithium value chain, as well as climate-smart agriculture (and land use) options. Given Argentina’s context, this CCDR focuses on win-win policies and investments, which have large co-benefits or can contribute to raising the country’s growth while helping to adapt the economy, also considering how human capital actions can accompany a just transition.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 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.
