global poverty declining

The World Bank estimates of poverty are published via Povcal Net and also in the World Development Indicators. Bourguignon, François and Christian Morrisson. The number of people living in extreme poverty continues to plunge despite slowing global growth, the World Bank says. When richer individuals or households are less likely to answer surveys than poor people, survey-based estimates of consumption and income will understate the mean level of prosperity and overstate the share of people in poverty. self-reported life satisfaction), basic needs (e.g. Do poverty traps exist? Global poverty is one of the very worst problems that the world faces today. There is absolutely no reason to be complacent about poverty today – it remains one of the world’s very worst problems. The set of national poverty lines estimated by Jolliffe and Prydz suggests, in contrast to earlier findings by Chen and Ravallion, that there is substantial variation in poverty lines even among the poorest countries. As we can see, there is a positive correlation between these two measures of deprivation, but they are clearly not identical. So if you believe the world is worse off, you may surround yourself with news that tends to confirm that. Other, less traditional policies might work better. When price levels in a country are much lower than in the US, using US dollars at market exchange rates will significantly underestimate the value of incomes. Online here. Bourguignon, François and Christian Morrisson. Interestingly, the correlation is very strong, but is far from perfect. These are the fifteen countries that were chosen as reference. Journal of the European economic association, 10(1), 152-197. Given all this information, consumption, as per the definition above, could be estimated directly from (i), or as the difference between (ii) and (iii). Available from https://openknowledge.worldbank.org/, Atkinson, A. When data from only one survey year are available, the reference year mean is based on the survey mean by applying the growth rate in private consumption per capita from the national accounts. The two visualizations show the absolute yearly monetary value of the poverty gap, for the world (top chart) and country by country (bottom chart). Unfortunately, the slow developments that entirely transform our world never make the news, and this is the very reason why we are working on this online publication. Economic Imbalances. The implication is that, by definition, zero income is a feasible value, while zero consumption is not a feasible value—people with zero consumption would starve. In order to produce disaggregated estimates, the World Bank relied on new data from the Global Micro Database that augments survey data in 89 countries, by providing a set of harmonized household characteristics, enriching the other survey instruments used by the World Bank to measure poverty. May 18, 2016. As we can see, the overall figures for both employment and hours of work are similar across treatment and control in all of the evaluated programs and do not statistically differ. The most straightforward way to measure poverty is to set a poverty line and count the number of people living with incomes or consumption levels below that poverty line and divide the number of poor people by the entire population. This is an important reminder that one poverty line is not enough and we need to rely on several poverty lines – higher and lower than the international poverty line – to understand what is happening. Can we expect to achieve this? A more careful analysis of the argument reveals a complex reality. This evidence is partial, since it does not account for ‘general equilibrium effects’—that is, the potentially positive long-term effects that new manufacturing jobs have via more competition and higher salaries in other sectors of the economy. The first thing that this chart shows is that a large share of the world population lives on very low incomes. There were several major revisions between the first formulation of a global poverty line in 1978 and today. 15-7. In the latest adjustment the international poverty line is set to the threshold of living on less than $1.90 per day. In theory, measures of poverty derived from the National Accounts should match measures of poverty derived from household surveys, but in reality there are often substantial discrepancies. 2002. (2012). Poverty declined during the last generation because the majority of the poorest people on the planet lived in countries with strong economic growth. The latter are the countries which experienced income growth over these 54 years. As we mentioned above, poverty is multidimensional in nature, and it is therefore useful to try to measure poverty through alternative instruments that capture deprivation beyond income and consumption. The data is taken from Hans Rosling (2013) – Highlights from Ignorance survey in the UK published at Gapminder.org. The poverty line of 1.90 int.-$ per day was just introduced in 2015, so the 2002 paper uses the measure of ‘one dollar per day’. A poverty line of int.-$ 10 per day would include the very poorest (on less than $2) and those that are 5-times richer and would thereby hide important differences. In the map we show available estimates of the extreme poverty headcount ratio, country by country. For measurement purposes, children are considered to be poor if they live in a poor household (i.e. You can also switch to the ‘chart’ tab to see the change over time for individual countries or world regions; or you simply click on a country to see how the poverty headcount ratio has changed. As one would then expect, this is reflected in the data. This post asks whether such remarks are true. Extreme global poverty is rapidly declining, but 84% of Americans don’t realize it. EMBED. The former is the same metric we have discussed extensively throughout this entry. Countries of this type cannot be used in aggregation.”. The source defines the universe of low and middle income countries as all countries except: Australia, Belgium, Cyprus, Finland, France, Germany, Greece, Iceland, Ireland, Israel, Italy, Luxembourg, Japan, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, United Kingdom and United States. AEIdeas. Poverty declining in Latin America . Online here. 1979. While the share of extremely poor people has fallen faster than ever before in history over the last 30 years, the majority of people in the UK thinks that the opposite has happened, and that poverty has increased. Conceptually, poverty traps can also take place at a collective ‘macro’ level. Relative poverty can be measured using the poverty headcount ratio and the poverty gap index. “Over the last 25 years, more than a billion people have lifted themselves out of extreme poverty, and the global poverty rate is now lower than it has ever been in recorded history. This is the poverty headcount ratio. This poverty line defines people as poor if their income is below a certain fraction of the income of the person in the middle of the income distribution. This entry can be cited as: Our World in Data is free and accessible for everyone. As we can also see from this map, there are some countries with very few observations. Because of this it is important to measure poverty not just by one very low poverty line, but many other poverty lines as well. Blog: The number of extremely poor people continues to rise in Sub-Saharan Africa, Environmental and Social Policies for Projects. For a significant minority of countries, however, World Bank estimates are based on income surveys. The two last rounds of PPP factors estimated by the ICP are from 2005 and 2011 and the next one is scheduled for 2017. This makes using a fixed poverty line to define destitution as a binary ‘yes/no’ problematic. In the World Bank estimates of global extreme poverty, high-income countries are not accounted for. About half of the world’s countries now have poverty rates below 3 percent, but the report finds that the world as a whole is not on track to achieve the target of less than 3 percent of the world living in extreme poverty by 2030. The share of correct answers differs substantially across countries. Bear in mind that these are estimates of household per capita income. The source is: Chandy, L., and C. Smith. Sarah Gustafson. So, what is the impact of these jobs on the welfare of the workers doing them? Banerjee, A., Duflo, E., Goldberg, N., Karlan, D., Osei, R., Parienté, W., … & Udry, C. (2015). The MPI is constructed from ten indicators across three core dimensions: health, education and living standards. Global data and statistics, research and publications, and topics in poverty and development. Kraay, A., & McKenzie, D. (2014). (2015 to 2030) Projected share of the population in extreme poverty; Share of global population living in extreme poverty including and excluding China “How Poor Are America’s Poorest? In this chart, countries with stagnant incomes are close to the blue 45° line, while countries with incomes that rose between 1960 and 2014 are above the 45° line. Alkire, S., & Foster, J. We don’t have estimates for GDP per capita for all poor countries in 1990 and 2017. In the case of expenditures, different reference periods are used to record responses across different categories of goods, with longer periods for goods or services that tend to be acquired less frequently. (2016) provide simple regression results and conclude that “After conditioning on other individual and household characteristics, having fewer than three children, having greater educational attainment, and living in an urban area are strongly and positively associated with economic well-being”. Shown in dark blue is the declining share of the Chinese population living below the International Poverty Line (1.90 int.-$), according to World Bank estimates. To produce aggregate statistics, the sum of all such shortfalls across the entire population in a country (counting the non-poor as having zero shortfall) is often expressed in per capita terms. Recent estimates for global poverty are that 9.2% of the world, or 689 million people, live in extreme poverty on $1.90 or less a day, according to the World Bank. Washington, DC. Chen, S., & Ravallion, M. (2001). The evidence suggests that multi-pronged interventions aimed at relieving multiple joint constraints at the household-level, are more likely to reduce poverty than ‘big push’ policies on the macro-level. The pioneering work that set out to count the number of people in poverty using a common global standard was published by Montek Ahluwalia, Nicholas Carter, and Hollis Chenery in 1979.53 The three authors based their estimates of global poverty figures on the Indian poverty line at the time. Agricultural outputs are then calculated by multiplying the acreage for each crop by the yield per acre. New goals were set to reduce poverty to three percent by 2030. September 2002, Volume 7, Issue 3, pp 195–225. One way to think about this is to consider how low prosperity is before an economy achieves sustained economic growth that lifts the majority of the population out of poverty. In their own words, they ‘line up’ country estimates to a reference year in order to produce regional and global totals. On any average day in the last decade the number of people living on more than $10 increased by almost a quarter of a million (246,500).22. Despite efforts to broaden the definition of incomes for the purpose of measuring poverty, in many countries statistical agencies still use definitions that fail to account for the consumption that occurs out of ‘non-income’ resources such as savings and assets, borrowing, and some forms of government welfare benefits. Deaton, Angus (2005) “Measuring Poverty in a Growing World (or Measuring Growth in a Poor World)” Review of Economics and Statistics, 87(1): 1–19. It is just hard to picture what life is like when all you know is a “dollar-per-day” figure. Poverty at the International Poverty Line of $1.90/day (in 2011 PPP). Botswana (38-fold increase), South Korea (30-fold), Romania (15-fold), China (11-fold), and Thailand (18-fold) are some of the countries with the strongest growth over these 54 years. Despite the clear evidence, many people are not aware of the fact that extreme poverty is declining across the world. As we can see, the monetary value of the global poverty gap today is about half of what it was a decade ago. This difference in the definition of poverty should be kept in mind when comparing the following graph to those discussed in other sections of this entry. What are the main indicators used to measure poverty? 4/25/17 - Bill Nye Off the Deep End, Free Speech and Colleges, Declining Global Poverty Rates Audio Preview remove-circle Share or Embed This Item. Accordingly, the share of people in extreme poverty has decreased continuously over the course of the last two centuries. The conclusion is that although poverty measurement instruments in high income countries are not designed to be compatible with instruments in low and middle income countries, the available evidence suggests that extreme poverty—as defined by the World Bank’s International Poverty Line—is likely to be very low in rich countries. When citing this entry, please also cite the underlying data sources. The number of people living on less than $1.90 per day has declined. In a time of unprecedented population growth, we managed to lift more and more people out of the extreme poverty of the past. A fundamental question that cuts through this topic is whether we have a good sense of the actual cost of ending poverty. WASHINGTON, Sept. 19, 2018 Fewer people are living in extreme poverty around the world, but the decline in poverty rates has slowed, raising concerns about achieving the goal of ending poverty by 2030 and pointing to the need for increased pro-poor investments, the World Bank finds. Debunking the Stereotype of the Lazy Welfare Recipient: Evidence from Cash Transfer Programs Worldwide. Based on this correlation between nighttime lights and economic activity, Pinkovskiv and Sala-i-Martin evaluate the relative quality of income data derived from household surveys and National Accounts. Above, we discussed the methodology used by the World Bank to measure extreme poverty. This is a point we discuss below in more detail. 2018 could be a landmark moment in understanding global poverty dynamics. The poverty rate estimates come from the World Bank (2016 PovCal release, using 2013 household survey data);26 and total population estimates come from the World Development Indicators. April 8, 2016 January 15, 2020. 2016 and Castaneda et al. The following visualization uses this source to provide a characterization of those who live in extreme poverty. In theory, both approaches should give the same result. As the last part of the conclusion above notes, a common concern among policymakers is that welfare programs can potentially discourage work—in fact, this is a concern that is shared by policymakers in both low- and high-income countries. Available at SSRN or http://dx.doi.org/10.2139/ssrn.2593894. In other entries in Our World In Data we discuss evidence that allows tracking progress in other aspects of welfare that are not captured by standard economic indicators. As the graph shows for GDP per capita, assessing living standards using PPP adjusted international dollars rather than US market dollars can make a huge difference. It plots, for each country, the national income in 1960 against the corresponding national income in 2014. Do poverty traps exist? In the top panel, the authors graph the employment rate for all eligible adults in both the control and treatment arms for each evaluation. According to these household surveys, 44% of the world population lived in extreme poverty in 1981. Poverty rates around the world are actually declining, and you can play a big part in driving this progress. In most cases, surveys are representative at the national level and record responses provided by ‘primary respondents’ such as the head of the household. The second approach is commonly used to establish a rental equivalent for housing and durable goods owned by the household. Of course, from a social welfare point of view, these effects have to be considered in conjunction with the effects on ‘native’ workers in the new host environments. “A global count of the extreme poor in 2012: data issues, methodology and initial results.” The Journal of Economic Inequality 14, no. If you think the international poverty line should be much higher and should instead be 4,000 int.-$, then you see that in 2003, 80% of the world population was below that poverty line. Allowances are made for the size and composition of households so that, for example, in a household with 2 adults and 2 children, the poverty line is roughly equivalent to $16.5 per person per day. So there were 1.9 billion extremely poor people and 2.6 billion people not in extreme poverty. A key difficulty in measuring global poverty is that price levels are very different in different countries. Both measures for each household come from the same survey. The World Bank Group works in every major area of development. And, with a still higher IPL of $5.50 per day, the head count would have increased from 2 billion to 2.6 billion between 1990 and 2015, if East Asia and the Pacific are kept out. The International Poverty Line is the best known poverty line for measuring absolute poverty globally. This reaffirms the importance of measuring poverty beyond just income and consumption, and of maintaining a nuanced understanding of how global living conditions change. Above we showed that poverty correlates with health. So if you believe the world is worse off, you may surround yourself with news that tends to confirm that. To answer this question, Blattman and Dercon (2016)46 ran a policy experiment in Ethiopia. In absolute numbers this meant the number of people who live on more than 10 dollars per day increased by 900 million in just the last 10 years.2, This expansion of the global middle class went together with progress in reducing global poverty – no matter what poverty line you want to compare it with, the share of the world population below this poverty line declined.3 In 1990 international organizations adopted a definition of poverty in line with the poverty lines in low-income countries. The World Bank is the main source for global information on extreme poverty today and it sets the ‘International Poverty Line’. There are many possible mechanisms—one is the lack of financial resources. In 1981 almost one third (29%) of the non-Chinese world population was living in extreme poverty. As mentioned above, a ‘poverty trap’ is a situation where incomes are stagnant over long periods, because ‘poverty today causes poverty in the future’. In the past three years, 9 million people have been lifted out of extreme poverty which is defined as living on US$ 1.25 a day or less. In American Economic Review, 92, 4, 727–744. The area of each bar (height times width) gives the number of individuals living in extreme poverty within each age bracket—these are the numbers written inside each bar. It’s inundated with opinion pieces and allows us to live in a kind of echo chamber. Countries where more people live in extreme poverty tend to have particularly bad health outcomes. The authors find that nighttime lights are much more closely correlated with GDP per capita than with survey means. Bounding the price equivalent of migration barriers. Global poverty has fallen to a record low. The historical decline of extreme poverty in China . How poverty changes is not only a consequence of economic growth, it also depends on the distribution of incomes and how this inequality changes during the growth process. Journal of development Economics, 98(1), 3-18. How can human rights approaches contribute in creating more effective responses to combating poverty and inequality? Abstract. Do poverty traps exist? Indeed, ‘extreme poverty’ is an adequate term for those living under this low threshold. That is a very poverty line and focusses on what is happening to the very poorest people on the planet.4. By virtue of being approximations, the World Bank poverty estimates can underestimate, as well as overestimate the size of the underlying problem. Counting and multidimensional poverty measurement. Available online here. Since then those economies have grown faster than many of the richest countries in the world and did much to a reduction of global inequality. US $2 a Day Poverty in a Global Context.” Policy Paper 2014-03, Brookings Institution, Washington, DC. Their research can be found in Sala-i-Martin & Pinkovskiy – Parametric estimations of the world distribution of income. A common argument put forward is that these industrial manufacturing jobs are a powerful instrument for reducing poverty, even if salaries tend to be very low by the standards of rich countries. To ensure that ‘no one is left behind’ as the SDG agenda promises, this is where we need to focus our efforts. But it is clear that the world has made progress against it. Global poverty measures are revised accordingly, back to 1990. On every day in the last 25 years there could have been a newspaper headline reading, “The number of people in extreme poverty fell by 128,000 since yesterday”. Global economic inequality – Our entry on the global distribution of incomes. This suggests that economic prosperity is not a vain, unimportant goal but rather a means for a better life. However, we are currently far off track to ending extreme poverty – we expect half a billion people to still live on less than $1.90 per day by 2030. Two-thirds of the world population live on less than 10 $-int per day. Without the increase in productivity that brought economic growth, it would not have been possible to lift hundreds of millions of people out of extreme poverty. In addition, how is the COVID-19 pandemic affecting poverty levels. As a result, they have resulted in sometimes substantial reductions in poverty among beneficiaries—especially when the transfer has been generous, well targeted, and structured in a way that does not discourage recipients from taking other actions to escape poverty.”. This relaxes the liquidity constraint and opens a window of possibility for policies aiming to promote migration, both within and across countries. (2016),54 shows in detail how the International Poverty Line has been updated over time. The report launch event will be webcast on World Bank Live at 12:30 p.m. Eastern time on Oct. 17. The following visualization provides evidence of this relationship. Jolliffe and Prydz (2016)56 address this issue of comparability by estimating the national poverty lines that are implied by poverty rates.57. In these poorer countries more people understand how global poverty has changed. This is the so-called poverty headcount ratio. By looking at the total number of people in extreme poverty (area of the bars) we can also see another important fact: virtually half of the people living in extreme poverty are under 18 years of age. Oct 19, 2018 - The economic growth that has lifted countries from low-income status to middle-income status is profoundly unequally distributed. Blattman, C., & Dercon, S. (2016). Data and research help us understand these challenges and set priorities, share knowledge of what works, and measure progress. Consumption is defined as “the use of resources whether acquired through purchase (expenditure) or through household production or provided from outside the household, such as by relatives, charities, or the government”.51. This second approach was first explored by Ahluwalia et al. (2016). As we can see, there is once again a clear negative relationship: poverty tends to be more frequent in countries where education is less developed. The data source is: Hellebrandt, Tomas and Mauro, Paolo (2015) – The Future of Worldwide Income Distribution (April 1, 2015). The idea for this chart is taken from Deaton (2010) – Price Indexes, Inequality, and the Measurement of World Poverty. A global ‘dollar-a-day’ poverty line was introduced in the World Development Report in 1990, and was subsequently used for the formulation of the Millennium Development Goals and the commitment to “halve, between 1990 and 2015, the proportion of people whose income is less than $1 a day.”. Fouquet, R., & Broadberry, S. (2015). Methods of household consumption measurement through surveys: Experimental results from Tanzania. Just a decade decade ago it was only a quarter. The first chart provides regional estimates of poverty counts – the total number of people living below the International Poverty Line in each world region. The Bourguignon and Morrison estimates for the past are based on national accounts and additional information on the level of inequality within countries. Working Paper. Absolute poverty is measured relative to a fixed standard of living; that is, an income threshold that is constant across time. This is now different. The declining share of people below higher poverty is also shown in this visualization. Keeping in mind that the World Bank poverty estimates are only approximations is important when making policy decisions, such as the allocation of international aid. In other words, the most common approach is to calculate the income or consumption shortfall from the poverty line. Global poverty is declining, but why does nobody believe it? As we can see, today, Africa is the continent with the largest number of people living in extreme poverty. See the Gapminder Ignorance Project for more evidence. After seeing the data for 2003 to 2013, the data shown here should not be surprising: Globally the share of people below any poverty line – $1.90, $3.20, $5.50, $10 – is declining. In this entry we focus mainly on welfare as measured by ‘monetized’ consumption and income, following the approach used by the World Bank. Sometimes it is falsely asserted that the global decline of extreme poverty is only due to the increasing prosperity of China. Policy Research Working Paper 7845. However, this variation does not seem to contradict the choice of the International Poverty Line: if we order the poverty lines of the poorest 25 percent of countries, the value in the middle is close to 1.90 int.-$. In fact, the big success over the last generation was that the world made rapid progress against the very worst poverty. Assessing the evidence. We use social media more and more. In Sub-Saharan Africa however the number of people in extreme poverty has increased and we explained at the beginning of this entry various projections expect that extreme poverty will be increasingly concentrated in Africa. The above discussion of data limitations in the context of World Bank poverty estimates highlights an important fact: any estimate of poverty—of either its level or change over time—is surrounded by a margin of error. Half a billion projected to live in extreme poverty in 2030. The second point to consider is that even if we try to apply the same standards used by the World Bank, the survey instruments in rich countries are typically not suitable to produce estimates that are comparable to those published by the World Bank. Yet, on the other hand, these jobs tend to be unpleasant and very poorly paid opportunities even by the standards of low income countries. But given that the poverty line is very low, and some countries have more poor people than others, it’s often easy to lose perspective on the actual absolute magnitude of the numbers we are dealing with. The same international organizations that set the poverty line made it a global goal to end extreme poverty. What this distribution shows is that global income inequality is extremely high. The scatter plot is interactive—by moving the time slider under the plot, you can see the change over time. The decline from almost every Chinese person living in extreme poverty to almost no Chinese people living in extreme poverty is of course an exceptional achievement.
