Shared Prosperity: A challenging but important goal to monitor

Judy Yang's picture

Shared prosperity is one of the World Bank Group’s Twin Goals, introduced in 2013. Progress toward this goal is monitored through an indicator that measures the annualized growth rate in average household per capita income or consumption among the poorest 40 percent of the population in each country (the bottom 40), where the bottom 40 are determined by their rank in household per capita income or consumption. Chapter 2 of the 2018 Poverty & Shared Prosperity Report provides an update on the recent mixed progress on shared prosperity around the world in about 2010-15.

The shared prosperity indicator was proposed as a means to shine a constant light on the poorest segments of the population in every country, irrespective of their level of development. Shared prosperity has no target or finish line, because the aim is to continuously improve well-being. In good times and in bad, in low and high-income economies alike, the bottom 40 percent of the population in each nation would be monitored. Tracking the bottom 40’s absolute growth as well as their growth relative to the mean is a way to remind us to always consider distributional impacts and strive for equitable outcomes.

An important but challenging goal to monitor

Despite its importance and universal relevance, shared prosperity is more challenging to monitor than global poverty. While one household survey is sufficient to calculate poverty, shared prosperity measurement requires two recent comparable surveys.

The implication of this stronger data requirement is that 91 out of the 164 economies with an international poverty rate measured in PovcalNet are included in the 6th edition of the Global Database of Shared Prosperity (GDSP).

Poverty lies beyond the unemployed

Globally, poverty by employment status is highest among unpaid workers (22 percent), followed by self-employment, and those out of the labor force (both 12 percent). Not surprisingly, income-earning capacity (proxied by employment status) is strongly associated with poverty and gender. When disaggregated by sex, there are roughly equal numbers of men and women among the poor who are unemployed. There are more men than women among the self-employed poor. However, women make up most of the poor who are unpaid workers or out of the labor force.

More than money: Counting poverty in multiple forms

Consider two households that have the same level of consumption (or income) per person but they differ in the following ways. All the children in the first household go to school, while the children in the second household work to support the family. The first household obtains drinking water from a tap connected to the public distribution network, whereas the second household fetches water from a nearby stream. At night, the first home is illuminated with electricity, whereas the second home is dark. A lay person would easily recognize which of these two families is better off. Yet, traditional measures of household well-being would put the two households on par because conventionally, household well-being has been measured using consumption (or income).

Nearly 1 in 2 in the world lives under $5.50 a day

Today, less than 10 percent of the world population lives in extreme poverty. Based on information about basic needs collected from 15 low-income countries, the World Bank defines the extreme poor as those living on less than $1.90 a day. However, because more people in poverty live in middle-income, rather than low-income, countries today, higher poverty lines have been introduced. These lines are $3.20 and $5.50 a day, which are more typical of poverty thresholds for middle-income countries.

Introducing the online guide to the World Development Indicators: A new way to discover data on development

The World Development Indicators (WDI) is the World Bank’s premier compilation of international statistics on global development. Drawing from officially recognized sources and including national, regional, and global estimates, the WDI provides access to almost 1,600 indicators for 217 economies, with some time series extending back more than 50 years. The database helps users—analysts, policymakers, academics, and all those curious about the state of the world—to find information related to all aspects of development, both current and historical.

An annual World Development Indicators report was available in print or PDF format until last year. This year, we introduce the World Development Indicators website: a new discovery tool and storytelling platform for our data which takes users behind the scenes with information about data coverage, curation, and methodologies. The goal is to provide a useful, easily accessible guide to the database and make it easy for users to discover what type of indicators are available, how they’re collected, and how they can be visualized to analyze development trends.

So, what can you do on the new World Development Indicators website?

1. Explore available indicators by theme

The indicators in the WDI are organized according to six thematic areas: Poverty and Inequality, People, Environment, Economy, States and Markets, and Global Links. Each thematic page provides an overview of the type of data available, a list of featured indicators, and information about widely used methodologies and current data challenges.

A massive new dataset to help promote health equity and financial protection in health

Adam Wagstaff's picture

Today we’re (re)launching HEFPI—aka the Health Equity and Financial Protection Indicators database. HEFPI sheds light on two major concerns in global health: a concern that the poor do not get left behind in the rush to achieve global health goals; and a concern that health services should be affordable. Neither concern featured in the MDGs; both feature prominently in the SDGs.

The HEFPI database draws on data from over 1,600 household surveys, including the Demographic and Health Survey and the Multiple Indicator Cluster Survey. Most of the 1,600 surveys have been re-analyzed in-house to ensure comparability across surveys and years, since published indicators from different surveys often use different definitions. We have settled on a definition based on recommendations in the relevant literature, and have used that across all surveys and time periods. As a result, the numbers in HEFPI are often different from (and more comparable than) numbers published elsewhere.

The database is, in effect, the fourth in a series. The first was in 2000. That database focused entirely on MDG-era health service and health outcome data—so no financial protection data. It covered just 42 countries, each with one year’s worth of data. The second (in 2007) and third (in 2012) gradually expanded the scope, with the 2012 dataset covering both financial protection and health equity, and getting up to 109 countries, including some high-income countries.

Behind Closed Doors: how traditional measures of poverty mask inequality inside the household and a new look at possible solutions

Caren Grown's picture

During the days coming up to, and after October 17, when many stories, numbers, and calls for action will mark the International Day for the Eradication of Poverty, we want to invite you to think for a second on what you imagine a poor household to be like. Is this a husband, wife, and children, or maybe an elderly couple? Are the children girls or boys? And more importantly, do all experience the same deprivations and challenges from the situation they live in?  In a recent blog post and paper, we showed that looking at who lives in poor homes—from gender differences to household composition more broadly—matters  to better understand and tackle poverty.

Globally, female and male poverty rates—defined as the share of women and men who live in poor households—are very similar (12.8 and 12.3 percent, respectively, based on 2013 data). Even in the two regions with the largest number of poor people (and highest poverty rates)—South Asia and Sub-Saharan Africa—gender differences in poverty rates are quite small. This is true for the regions, but also for individual countries, irrespective of their share of poor people. Why is that the case? As Chapter 5 of the 2018 Poverty and Shared Prosperity Report explains, our standard monetary poverty indicator is measured by household, not by individual. So, a person is classified as either poor or nonpoor according to the poverty status of the household in which she or he lives. This approach critically assumes everyone in the household shares equally in household consumption—be they a father, a young child, or a daughter-in-law.  By design, it thus masks differences in individual poverty within a household.

Notwithstanding this shortcoming, when we look a bit deeper the information we have today still shows visible gender differences in poverty rates. Take age, for example. We know that there are more poor children than poor adults, and while we do not find that poverty rates differ much between girls and boys at the early stages of life, stark differences appear between men and women during the peak productive and reproductive years.

Incomes of the poorest are growing in 3 of every 4 economies

Maria Ana Lugo's picture

In much of the world today, the incomes of the poor are growing. The World Bank calls this concept shared prosperity, defined as the average annual growth in income or consumption of the poorest 40 percent (the bottom 40) within each country. So, if shared prosperity in a country is positive, the poor are getting richer.

In addition, the shared prosperity premium is defined as the difference between the annual income or consumption growth rate of the bottom 40 and the annual growth rate of the mean in the economy. A positive premium indicates that the bottom 40 are getting a larger share of overall income in the economy.

Global poverty in 2015: PovcalNet’s new estimates and improved documentation

Christoph Lakner's picture

PovcalNet released new poverty estimates last week, indicating that in 2015, 10 percent of the global population were living on less than the international poverty line (IPL), currently set at US$1.90 per person per day in 2011 purchasing power parity (PPP). This estimate is based on a series of new data and revisions, including more than 1,600 household surveys from 164 countries, national accounts, population estimates, inflation data, and purchasing power parity data. The new poverty numbers were released on September 19 and will be part of “Poverty and Shared Prosperity 2018: Piecing Together the Poverty Puzzle,” a report to be published on October 17, End Poverty Day.

We’re also launching a Global Poverty Monitoring Technical Note Series which describes the data, methods and assumptions underpinning the World Bank’s global poverty estimates published in PovcalNet. With this update, we’re releasing four new notes in this series, including the “What’s New” note that will accompany each of the semi-annual updates to PovcalNet. The other notes cover different aspects of the price adjustments embedded in the global poverty estimates, such as adjustments for inflation and price differences across countries

Begun as a research project by Martin Ravallion, Shaohua Chen and others, PovcalNet has become the official source for monitoring the World Bank’s Twin Goals, the Millennium Development Goals (MDG), and now Sustainable Development Goal 1.1. PovcalNet is managed jointly by the Data and Research Groups within the World Bank’s Development Economics Division. It draws heavily upon a strong collaboration with the Poverty and Equity Global Practice, which is responsible for gathering and harmonizing the underlying survey data.

PovcalNet does much more than simply providing the most recent global poverty estimates. It’s a computational tool that allows users to estimate poverty rates for regions, sets of countries or individual countries, over time and at any poverty line. It also provides several distributional measures, such as the Gini index and income shares for the various decile groups.

The most recent PovcalNet data show us that over the last few decades, remarkable progress has been made in reducing extreme poverty. The world attained the first MDG target—cutting the 1990 poverty rate in half by 2015—six years ahead of schedule. With continued reductions, the global poverty rate, defined as the share of world’s population living below the IPL, has dropped from 35.9 percent in 1990 to 10 percent in 2015 – more than a 70 percent reduction.

In the last quarter century, global poverty dropped by more than 70 percent
