Poverty measures and definitions

In this article an attempt is made to explain what poverty means and how it is measured. Absolute income measures are discussed with reference to England, America, Australia and South Africa. These encompass the poverty line, the social security administration measure, the Henderson poverty line, the South African poverty datum line and the poverty gap. Relative income measures of poverty used in England, America and Australia are described. Absolute measures of poverty, the income‐net worth approach, a definition that includes other resources and a balance sheet method are explained. Socio‐economic measures are dealt with. These include the sociological concept of poverty, socio‐economic status measures and the culture of poverty view. Other measures described are public dependency and residential measures, mortality measures, a normative measure and subjective poverty.     

Spatial Patterns of Inequality and Poverty in Indonesia

The paper uses data from the 1976 Household Expenditure Survey (Susenas) to examine spatial patterns of poverty and inequality in Indonesia. A number of inequality measures are computed for each province (Gini Ratio. Atkinson Index, Theil Index, L-Index) and provincial rankings according to each index are compared. Provinces are also ranked according to a number of poverty indexes, using a poverty line adjusted for differences in price levels, between provinces. The correlation between selected measures of poverty and inequality is also investigated and some implications for regional development policy discussed.     

General Equilibrium Approach for Poverty Analysis: With an Application to Cameroon

Abstract: In this paper we use a computable general equilibrium model to study the impact of a trade shock and a tariff reform on household poverty for an archetype developing country. Unlike other studies, we present the income distribution of each household group as a Beta statistical distribution. In contrast to other studies, this paper presents the poverty lines as being endogenous. With this specification, the poverty line will change following a variation in relative prices. With the new distributions and poverty line, the poverty levels of the base year are compared with the ex‐post values. Foster, Greer and Thorbecke's (1984) poverty measures are used. We work with the Cameroon household survey data of 1995–96. We consider two scenarios. The first is a 30 percent fall in the world price of the country's export crop and the second is a reduction of 50 percent in the country's import tariffs. For the first simulation, results indicate a drop in all household incomes and a decrease in the poverty line. Unilateral trade liberalization also has negative consequences on all household incomes. As in the first simulation, the poverty line decreases with a unilateral trade liberalization. In the trade liberalization simulation, the poverty line effect counters the income effect in most cases analyzed. In the other simulation, the poverty line effect attenuates the decrease in the poverty measures.     

Poverty and Inequality Maps in Rural Vietnam: An Application of Small Area Estimation

The objective of the present paper is to estimate poverty and inequality for rural Vietnam at different levels of aggregation by combining the Vietnam Household Living Standard Survey from 2006 and the Rural Agriculture and Fishery Census from the same year. Using the small area estimation method, estimates at the regional, provincial and district level are produced, and both expenditure and income based measures are considered. It is found that all provinces across the country have experienced a noticeable reduction in rural poverty during the period 1999–2006. Some of the largest reductions in poverty are observed for provinces with poverty rates close to the national average. The poorest provinces are experiencing reductions in poverty, albeit at a more modest pace. Provinces and districts with a larger poverty reduction in the period 1999–2006 tended to have a lower level of inequality in 2006. Results based on expenditure poverty estimates are found to be very similar to those based on income poverty estimates.     

Revisiting the Impact of Consumption Growth and Inequality on Poverty in Indonesia during Decentralisation

This article analyses the consumption growth elasticity and inequality elasticity of poverty in Indonesia, with a particular focus on the decentralisation period. Using provincial panel data, we show that the effectiveness of growth in alleviating poverty across provinces was greater during decentralisation—that is, between 2002 and 2010—than at any other point since 1984. The growth elasticity of poverty since 2002 is estimated to have been –2.46, which means that a 10% increase in average consumption per capita would have reduced the poverty rate by almost 25%. However, we also find that rising income inequality negated a quarter to a third of the 5.7-percentage-point reduction in the headcount poverty rate. This increasing inequality has contributed to a lower level of pro-poor growth than that maintained in Indonesia before decentralisation.     

Seebohm Rowntree and the postwar poverty puzzle

In his third social survey of York carried out in 1950, Seebohm Rowntree reported a steep decline since 1936 of the percentage of households in poverty. He attributed the bulk of this decline to government welfare reforms enacted during and after the war. This article re‐examines the survivingrecords from the 1950 survey, using a revised poverty line and looking more closely at the measurement of income. It also re‐assesses the impact of welfare reforms on working‐class poverty, and finds that poverty in York was significantly higher, and the contribution of welfare reform substantially less, than was originally reported.     

Measuring poverty with noisy and corrected estimates of annual consumption: Evidence from Nigeria

An opportunity to improve measurement and modelling of poverty in Africa arises from recent intra‐year panel surveys that observe household consumption in post‐planting and post‐harvest periods. Observing the same household twice lets an intra‐year correlation be estimated, which can be used to form a corrected estimate of annual consumption. The usual approach surveys consumption for just one short period, like a week or month, and extrapolates to an annual total. This may adequately estimate mean annual consumption for samples spread over a year but overstates dispersion. The resulting noise in consumption estimates inflates measures of poverty and inequality and creates misclassification errors that bias logit and probit models of poverty determinants. This study uses data from the 2012/2013 Nigeria General Household Survey panel to show effects on poverty measures of using annual estimates extrapolated from short‐period surveys. With the corrected extrapolation method that uses intra‐year correlations to adjust for inflated variances, Nigeria's poverty headcount rate falls by one half. Hence, much of the poverty measured in cross‐sectional surveys is transient poverty, for which different policy interventions are needed than for alleviating chronic poverty.     

Spatial Comparisons of Poverty and Inequality in Living Standards in Malawi

The paper looks at poverty and inequality across areas in Malawi. The focus is on both monetary (consumption) and non‐monetary (health and education) dimensions of well‐being. Stochastic poverty dominance tests show that rural areas are poorer in the three dimensions regardless of poverty line chosen. Stochastic inequality dominance tests find that the north and south dominate the centre in health inequality, and there is no dominance between the north and south. With respect to education inequality, dominance is declared for the south‐centre pair only. A subgroup decomposition analysis finds that the south contributes the most to consumption and education poverty, while the centre is the largest contributor to health poverty. We establish that within‐area inequalities (vertical inequalities) rather than between‐area inequalities (horizontal inequalities) are the major driver of consumption, health and education inequality in Malawi.     

The identification of towns in the Free State for an urban upgrading and development programme: A proposed method for consideration

This article describes how small towns in the Free State were assessed for a German‐South African urban upgrading and development programme. The assessment first determined where the programme would have a significant impact on the recipient community and, secondly, where it would have a high probability of success. Two criteria were used: quantitative (settlement types, demographic and economic trends, financial and management capacity and performance, and access to services and housing) and qualitative (level of community‐based participation in existing projects, the spirit of the place, economic potential and delivery record in terms of projects). These criteria reduced the number of appropriate towns to eight. A provincial steering committee (representing the political dimension) was appointed to incorporate the towns into the programme. They are representative of towns across the province, as well as a variety of settlement types. This method can be considered on a provincial or regional basis elsewhere for evaluating and ranking small towns for development support.     

Food Price Crisis,Poverty, and Inequality

This paper simulates how a doubling of food prices affects absolute poverty and the food‐price‐adjusted real income distribution. We assume unsubsidized world food prices in order to derive the cost of poverty deepening and poverty expansion. We also estimate the degree to which inequality increases if no measures are put in place to offset rising food prices. Both measures are vulnerability indicators useful for social policy planning. Our results show that low‐income countries experience dramatic increases in absolute poverty as a result of doubling food prices. Middle‐income countries experience the greatest decrease in absolute income, which contributes most to an increase in world income inequality. The paper estimates that the global dollar value of the absolute poverty gap ($1.25/day) has the potential to increase by 400%, with poverty deepening accounting for two thirds of the increase.     

A multidimensional analysis of poverty in China from 1991 to 2006

Most studies have reported non negligible improvements for China in terms of poverty during the last three decades. However, this result is potentially hampered by two limitations. First, it may be contingent to the specific choices made regarding the poverty line and the poverty indices used for the analysis. As a consequence, it may collapse if one uses alternative poverty lines or poverty measures. Second, it results from a focus on the sole monetary aspects of poverty. As income does not cover all facets of well-being and since the relationship between these two concepts are quite fuzzy, it may be worth using a broader view of well-being, hence opting for a multidimensional approach of poverty analysis. In the present paper, these two issues are addressed using multidimensional stochastic dominance procedures on the joint distribution of income, education and health in seven Chinese provinces.     

我国现行农村贫困标准的完善

进入新世纪,我国农村挟贫效益呈现出递减态势,其原因固然众多,但农村贫困标准的缺陷应是首当其冲,因为贫困标准是监测贫困状态、制定反贫困政策的重要理论依据和行动指南。文章从贫困标准的总体水平、内部构成、动态化、多样化、国际化等方面对我国当前农村贫困标准的缺陷与完善进行了全面探讨。     

黄渤海地区影响农业产出因素的分析——基于Panel Data 模型

通过对黄渤海地区两市五省2002年—2012年农业产出进行描述性分析,并选取农业总产值作为代表农业产出水平的指标,将各省农业在经济中的地位、联合收获机的年末拥有量、化肥施用量、播种面积、受灾面积以及农村劳动力文化水平作为影响农业总产值的因素,利用2002年—2012年的省际面板数据,采用stata进行计量分析,对影响黄渤海地区各省农业总产值的因素进行测度。研究结果表明,我国黄渤海地区农业总产值受生产条件的影响较大;第一产增加值占GDP的比重对农业总产值也有较显著的影响,而劳动力文化水平程度的影响并不是很显著。     

Measuring the poverty lines for urban households in China—an equivalence scale method

Laid-off employees in the state-owned enterprises (SOEs) due to China's economic reform and the enterprise-restructuring plan created newly urban poverty, lending urgency to the task of constructing accurate measures of poverty thresholds. Along this line, a fundamental question is: given the widely used poverty threshold for an individual, how should that threshold vary across households with different demographic characteristics? Equivalence scales, which can be used to derive comparable poverty lines for households of different sizes and compositions and in different regions, are ideally suited for providing answers to this question. Accordingly, this paper uses the Urban Household Survey (UHS) data of China to estimate the equivalence scales for Chinese urban households. The results provide a quantitative reference to calculate the comparable poverty lines for households with different demographic compositions. A useful byproduct of this study is a specification of the demand system of China.     

A distributional approach to comparing vulnerability,applied to rural provinces in Thailand and Vietnam

Vulnerability to poverty is an important social indicator of well-being. Yet, comparisons of vulnerability over time or space lack robustness as long as they are based on single measures or use specific poverty lines. We demonstrate that a distributional analysis, based on stochastic dominance orders, can help. Using data from six rural provinces of Thailand and Vietnam, we establish cumulative distribution functions for income and consumption at the provincial level and show how they can provide ethically robust vulnerability comparisons.     

Alternative Poverty Lines for Malaysia

Because of the shortcomings of the Malaysian official poverty line, this paper offers several alternative regional poverty line estimations with varying underlying assumptions. Using the Household Expenditure Survey 2004/2005, poverty lines are estimated based on the consumption patterns of 10th and 20th percentile household per capita expenditure. The regional poverty lines from these reference groups produced robust poverty measurement rankings across regions in the country. We suggest that the poverty lines from both reference groups be used as lower and upper poverty lines for the country.     

Patterns of poverty in South Africa

This article brings together results from two large household surveys ‐ the October Household Survey and the Income and Expenditure Survey of 1995. The analysis adopts a simple definition of income poverty which allows comparisons between households in ten deciles defined on the basis of per capita household income. The analysis compares access to resources such as housing and land, and access to basic services across these households. It then examines the economic status of women and men living in households with different incomes. The article shows consistent correlation of per capita income with other examined variables. It illustrates further how women within each decile are disad‐vantagedcomparedwith men in terms of economic status and earning.     

The determinants of rural and urban household poverty in the North West province of South Africa

Based on standard poverty measures, the extent of poverty in the North West province is on average worse than in South Africa. For instance, the poverty gap ratio for North West is twice that of the South African average, and the FGT index is three times as high. This article therefore aims to identify the determinants of rural and urban poverty in the North West province of South Africa. Using data gathered from a survey of 593 black households across the province, probit model estimates suggest that the major significant determinants of household poverty in both rural and urban areas are education and household size. A difference between rural and urban poverty is, first, that extra female adults in a rural household raise the probability of poverty. Secondly, having a migrant (out) worker as head of the household in rural areas lowers the probability of poverty, while this does not apply to urban households. A sensitivity analysis for the robustness of the results over a range of poverty lines reveals that the impact of education is much stronger for poorer households than for more wealthy households.     

Constructing migration: Infrastructure,poverty and development in KwaZulu‐Natal

Migration and population movement are probably the most neglected of the significant dynamics behind rural poverty in South Africa. Little is known about how people move from place to place, and much of what we thought we knew may be incorrect. In KwaZulu‐Natal job search is no longer the single dominating reason given for migration. Instead, infrastructure ties with it for first place today, with land close behind. The first article in this two‐part report notes that as many as two thirds of the province's disadvantaged families have broken away from their communities of origin and moved at least once during their lifetimes. Perhaps three million have migrated in the last fifteen years. A second unexpected finding is the predominance of rural‐to‐rural migration. Three quarters of all moves recorded were rural to rural, with many orientated towards advantaged rural areas around small towns and secondary cities. Results show how streams are channelled towards poverty or opportunity, and argue for a review of prevailing concepts of rural‐urban relations which structure delivery efforts. The second article, to follow later, notes that recorded income levels are now higher in some rural destination areas than in the urban shack communities that accommodate rural‐to‐urban migrants. Results of various studies presented show how access to information affects migration patterns, and the article also explores the role of infrastructure as a determining force in the regional distribution of population and as a factor in people's own bootstrap anti‐poverty efforts.
