measures a fixed standard of living, often based on a minimum income level
Relative poverty compares individuals' economic status to the overall population
Absolute poverty focuses on meeting basic needs (food, shelter, clothing)
Relative poverty considers social inclusion and participation in society
Choice between absolute and relative measures impacts policy approaches and resource allocation
Income-based measurements
Utilize household or individual income as the primary indicator of economic well-being
Often calculated as a percentage of median income (50% or 60% in many countries)
Advantages include ease of data collection and comparability across populations
Limitations involve not capturing non-monetary resources or informal economy contributions
Income-based measures may not reflect true living standards in areas with high costs of living
Consumption-based measurements
Focus on actual expenditure patterns rather than income
Include food, housing, healthcare, and other essential goods and services
Provide a more accurate picture of living standards in economies with large informal sectors
Account for savings, debt, and access to credit that income measures might miss
Challenges include data collection complexity and potential underreporting of consumption
Historical development
Poverty line measurements evolved alongside the development of social welfare systems
Understanding historical context helps explain current approaches to poverty measurement
Shifts in measurement methods reflect changing societal views on poverty and inequality
Origins of poverty thresholds
Emerged in the late 19th and early 20th centuries as industrialization highlighted urban poverty
Early poverty studies by Charles Booth in London and Seebohm Rowntree in York pioneered systematic measurement
Rowntree's 1901 study introduced the concept of a poverty line based on minimum subsistence needs
U.S. Social Security Administration developed the in the 1960s
Initial thresholds often based on food costs multiplied by a factor to account for other necessities
Evolution of measurement methods
Shifted from purely subsistence-based measures to include social participation aspects
Incorporation of relative poverty concepts in the 1970s and 1980s
Development of multidimensional poverty measures in the late 20th and early 21st centuries
Increased use of statistical techniques and large-scale surveys for more accurate data collection
Growing recognition of the need to account for regional cost-of-living differences
International poverty lines
Global poverty lines facilitate cross-country comparisons and track progress on poverty reduction
International measures help coordinate global development efforts and aid allocation
Understanding these lines is crucial for analyzing global inequality and social stratification
World Bank global standard
Currently set at $1.90 per person per day based on 2011 purchasing power parity
Represents the international poverty line for extreme poverty
Derived from the national poverty lines of the world's poorest countries
Used to track global poverty trends and progress towards Sustainable Development Goals
Criticized for being too low to reflect real poverty in many countries
Purchasing power parity adjustments
Account for differences in price levels and currencies across countries
Enable meaningful comparisons of poverty rates between nations
Calculated using a basket of goods and services to determine relative purchasing power
PPP adjustments crucial for setting appropriate international poverty thresholds
Challenges include accounting for quality differences and non-traded goods
Regional variations
World Bank introduced additional poverty lines of 3.20and5.50 for lower-middle and upper-middle income countries
Regional poverty lines account for differing living standards and economic contexts
Latin America and the Caribbean often use higher poverty lines due to higher overall incomes
Sub-Saharan Africa and South Asia typically have lower poverty lines reflecting lower costs of living
Regional variations highlight the importance of context in poverty measurement
National poverty lines
Reflect country-specific economic conditions and social norms
Essential for designing and implementing domestic poverty reduction policies
Understanding national lines helps analyze within-country social stratification
Country-specific thresholds
Determined by individual governments based on local economic and social factors
Often calculated using a combination of income and consumption data
May be absolute (fixed basket of goods) or relative (percentage of median income)
Updated periodically to account for changes in living standards and inflation
Examples include the U.S. and the UK's 60% of median income measure
Variations across states/regions
Many countries use different poverty lines for urban and rural areas
Account for differences in cost of living and consumption patterns within countries
Some federal systems (India, United States) allow states to set their own supplementary poverty lines
Regional variations can lead to debates about fairness in resource allocation and policy implementation
Challenges include balancing local specificity with national consistency in poverty measurement
Calculation methods
Various approaches exist to determine poverty lines, each with strengths and limitations
Choice of method impacts poverty estimates and subsequent policy decisions
Understanding calculation methods is crucial for interpreting poverty statistics in social stratification studies
Cost of basic needs approach
Estimates the cost of acquiring adequate food and non-food items
Food poverty line based on minimum calorie requirements and typical local diet
Non-food component added based on spending patterns of households near the food poverty line
Advantages include intuitive understanding and reflection of local consumption patterns
Challenges involve defining an appropriate reference group and accounting for quality differences
Food energy intake method
Determines the level of consumption or income at which a household acquires sufficient food energy
Calculates the expenditure level at which households typically attain minimum calorie requirements
Does not require defining a specific food basket, unlike the cost of basic needs approach
Advantages include simplicity and lower data requirements
Limitations include potential overestimation of poverty in areas with high food prices
Subjective poverty lines
Based on people's perceptions of their own economic situation and needs
Often determined through surveys asking about minimum income needed for adequate living
Reflect societal norms and expectations rather than externally defined standards
Advantages include capturing local context and social definitions of poverty
Challenges involve potential biases in self-reporting and difficulties in cross-country comparisons
Criticisms and limitations
Understanding critiques of poverty lines is essential for a nuanced analysis of social stratification
Recognizing limitations helps in developing more comprehensive approaches to poverty measurement
Critiques often highlight the complex, multidimensional nature of poverty beyond income or consumption
Inadequacy of income measures
Fail to capture non-monetary resources (subsistence farming, social networks)
Do not account for wealth accumulation or long-term economic security
Ignore access to public services (healthcare, education) that affect living standards
May not reflect true purchasing power in areas with high costs of living
Challenges in accurately measuring income in informal economies or rural areas
Neglect of non-monetary factors
Overlook important dimensions of well-being (health, education, social inclusion)
Fail to capture the impact of discrimination, social exclusion, or lack of political voice
Do not account for environmental factors affecting quality of life (pollution, natural disasters)
Ignore the importance of assets and resilience in coping with economic shocks
Limitations in reflecting the experiences of marginalized groups (women, minorities, disabled individuals)
Rural vs urban disparities
Standard poverty lines may not accurately reflect differences in living costs between rural and urban areas
Urban poverty often underestimated due to higher costs of housing, transportation, and services
Rural poverty may be overestimated if subsistence agriculture and lower living costs are not considered
Challenges in comparing poverty rates between rural and urban areas due to different consumption patterns
Difficulties in accounting for migration and remittances in poverty measurements
Alternative measurements
Recognition of poverty's multidimensional nature has led to the development of alternative measures
These approaches aim to capture a more comprehensive picture of poverty and well-being
Understanding alternative measures enhances the analysis of social stratification beyond income-based metrics
Multidimensional poverty index
Developed by Oxford Poverty and Human Development Initiative and the UN Development Programme
Measures deprivations across three dimensions: health, education, and standard of living
Includes indicators such as nutrition, child mortality, years of schooling, and access to basic services
Allows for decomposition of poverty by dimension and population subgroup
Provides a more nuanced understanding of poverty beyond monetary measures
Asset-based approaches
Focus on household ownership of durable goods and access to services
Include items such as vehicles, appliances, housing quality, and access to electricity or clean water
Advantages include stability over time and ease of measurement compared to income
Useful in contexts where income data is unreliable or difficult to collect
Limitations include not capturing short-term economic fluctuations or liquid assets
Capability approach
Developed by economist , focuses on individuals' freedoms and abilities
Emphasizes what people are able to do and be, rather than just their income or consumption
Considers factors such as political freedoms, social opportunities, and economic facilities
Informs the Human Development Index and other multidimensional measures
Challenges include difficulties in quantifying and comparing capabilities across diverse contexts
Policy implications
Poverty line measurements significantly influence social policy and resource allocation
Understanding these implications is crucial for analyzing the role of policy in addressing social stratification
Different measurement approaches can lead to varying policy responses and outcomes

Can affect the allocation of resources between different types of social programs
Challenges include balancing targeted assistance with broader social protection measures
Targeted interventions
Poverty measurements help identify specific groups or regions for focused poverty reduction efforts
Inform the design of conditional cash transfer programs targeting education or health outcomes
Guide geographic targeting of development projects in high-poverty areas
Assist in tailoring interventions to address specific dimensions of poverty (nutrition, housing, education)
Challenges include avoiding and ensuring inclusion of marginalized groups
Poverty reduction strategies
National and international poverty lines serve as benchmarks for setting poverty reduction goals
Influence the formulation of Poverty Reduction Strategy Papers (PRSPs) in developing countries
Guide the allocation of international aid and development assistance
Inform policy choices between growth-oriented and redistribution-focused strategies
Challenges include balancing short-term poverty alleviation with long-term structural changes
Poverty line vs other indicators
Comparing poverty lines with other socioeconomic indicators provides a more comprehensive view of inequality
Understanding these relationships enhances the analysis of social stratification across different dimensions
Integrating multiple indicators offers a more nuanced picture of societal well-being and development
Gini coefficient comparison
measures income inequality across the entire population
Poverty rates and Gini coefficient can move independently (high inequality with low poverty or vice versa)
Combining poverty lines with Gini coefficient provides insights into the distribution of poverty
High Gini coefficient with high poverty rate suggests deeply entrenched socioeconomic divisions
Low Gini coefficient with high poverty rate may indicate widespread but relatively equal deprivation
Human development index relationship
Human Development Index (HDI) incorporates health, education, and income dimensions
Countries may have similar poverty rates but different HDI scores due to variations in non-income factors
HDI can highlight development progress not captured by poverty reduction alone
Combining poverty measures with HDI offers insights into the quality of life beyond income poverty
Challenges include reconciling different methodologies and data sources between measures

Key Terms to Review (21)
Absolute poverty: Absolute poverty refers to a condition where individuals or families lack the minimum resources necessary to maintain basic living standards, such as food, clean water, sanitation, healthcare, and shelter. It is a severe state of deprivation that can lead to life-threatening situations. This concept connects deeply to issues surrounding economic inequality, the distribution of resources globally, and how poverty is measured in different contexts.
Amartya Sen: Amartya Sen is a renowned Indian economist and philosopher who is best known for his work on welfare economics, development theory, and social justice. He emphasizes the importance of capabilities and freedoms in assessing well-being, rather than merely relying on income or wealth indicators. His ideas have significantly shaped discussions around global poverty, social safety nets, and poverty measurement, highlighting the multidimensional aspects of poverty and the need for holistic approaches to development.
Asset-based approaches: Asset-based approaches focus on leveraging the resources, skills, and strengths that individuals and communities possess to improve their economic and social conditions. Rather than concentrating solely on deficits or needs, this approach emphasizes building upon existing assets to foster empowerment and enhance well-being, which can significantly impact poverty line measurements.
Capability approach: The capability approach is a theoretical framework that emphasizes individuals' abilities to achieve well-being and live a life they have reason to value. This approach shifts the focus from traditional measures of welfare, like income, to the actual capabilities that people have to pursue different opportunities and outcomes in their lives.
Conflict Perspective: The conflict perspective is a sociological approach that views society as an arena of inequality that generates conflict and change. It emphasizes how social structures and institutions perpetuate inequalities based on factors such as class, race, gender, and power dynamics, highlighting the struggles between different groups for limited resources.
Economic inequality: Economic inequality refers to the uneven distribution of wealth and income within a society, leading to significant disparities between different socioeconomic groups. This inequality can affect access to resources, opportunities, and overall quality of life, often perpetuating cycles of poverty and limiting social mobility.
Food Insecurity: Food insecurity refers to the state where individuals or households lack reliable access to sufficient, affordable, and nutritious food necessary for a healthy life. It is closely tied to socioeconomic factors, often highlighting disparities in wealth and resources among different groups in society. Understanding food insecurity requires examining the broader context of poverty measures and the challenges faced by lower-income families in securing adequate nutrition.
Functionalist perspective: The functionalist perspective is a sociological approach that views society as a complex system whose parts work together to promote solidarity and stability. This perspective emphasizes the role of social structures in maintaining social order and explains how various aspects of society, including institutions, norms, and values, contribute to the overall functioning of society. By analyzing how different elements serve a purpose, the functionalist perspective connects to understanding class structures, mobility, and inequalities.
Gini Coefficient: The Gini coefficient is a statistical measure used to represent income or wealth distribution within a population, ranging from 0 (perfect equality) to 1 (perfect inequality). It provides insight into the extent of inequality in a society, reflecting how evenly resources are distributed among individuals or households. A higher Gini coefficient indicates greater inequality, while a lower value suggests more equitable distribution.
Housing instability: Housing instability refers to the condition where individuals or families lack a stable, safe, and adequate place to live. This can include frequent moves, living in temporary accommodations, or being at risk of eviction or homelessness. It is often closely linked to poverty and social inequality, impacting access to education, health care, and employment opportunities.
Multidimensional Poverty Index: The Multidimensional Poverty Index (MPI) is a comprehensive measure that assesses poverty through multiple deprivations in health, education, and living standards, rather than solely income. It recognizes that poverty is not just about lack of money but also encompasses various aspects of human well-being, making it a more holistic approach to understanding poverty dynamics globally.
Official poverty measure: The official poverty measure is a statistical tool used to determine the poverty status of individuals and families in the United States, primarily based on income thresholds. This measure is calculated using a formula that considers family size and the cost of basic needs such as food, clothing, and shelter. The thresholds are updated annually to account for inflation, making it a crucial benchmark for understanding economic hardship and assessing the effectiveness of social policies.
Peter Townsend: Peter Townsend was a British sociologist and social policy expert known for his pioneering work on poverty and social inequality. He significantly influenced the understanding of relative poverty, emphasizing that poverty should be measured not just by income but by the ability to participate in society. His contributions are particularly relevant in discussions about global poverty and methods of measuring poverty lines.
Poverty Gap Ratio: The poverty gap ratio measures the intensity of poverty by calculating the average shortfall of income from the poverty line, expressed as a percentage of that poverty line. This ratio highlights not just the number of people living below the poverty line, but also how far below it they are, providing a clearer picture of poverty's severity and helping to inform policies aimed at alleviating poverty.
Poverty threshold: The poverty threshold is a specific income level established by government standards, below which individuals or families are considered to be living in poverty. This measurement plays a crucial role in identifying who qualifies for assistance programs and evaluating economic conditions within a society. The threshold is often updated annually to account for inflation and changes in the cost of living, ensuring that it accurately reflects current economic realities.
Rationalization: Rationalization refers to the process by which traditional methods of thinking and acting are replaced by more systematic, logical, and efficiency-driven approaches. This shift often involves the use of reason and calculations to achieve desired outcomes, leading to a more structured and predictable environment. In the context of social structures, rationalization plays a key role in understanding how social inequalities are perpetuated and measured, particularly in the way that poverty is quantified and addressed within society.
Relative poverty: Relative poverty refers to the condition where an individual or a group lacks the minimum income needed to maintain the average standard of living in the society they live in. This concept emphasizes the disparities between different segments of the population, focusing on how poverty is not just about survival but also about one's ability to participate fully in social and economic life. The understanding of relative poverty highlights its connection to issues like inequality, social inclusion, and the benchmarks used to measure living standards.
Social Mobility: Social mobility refers to the ability of individuals or groups to move up or down the social hierarchy, often measured by changes in income, education, or occupation. This concept is crucial for understanding how different social structures impact individuals' opportunities and outcomes, influencing the dynamics of class, access to resources, and overall societal inequality.
Stigmatization: Stigmatization refers to the process by which individuals or groups are marked as different, often in a negative way, leading to discrimination and social exclusion. This labeling can significantly impact people’s access to resources, opportunities, and support systems, influencing their social standing and life experiences. The effects of stigmatization can be seen across various societal issues, particularly those related to poverty, education, social safety nets, and measurements of economic hardship.
Supplemental Nutrition Assistance Program (SNAP): The Supplemental Nutrition Assistance Program (SNAP) is a federal assistance program designed to provide food-purchasing support for low-income individuals and families in the United States. SNAP aims to alleviate hunger and improve nutrition among those living in poverty by offering monthly benefits that can be used to buy eligible food items, thus acting as a crucial component of the nation's social safety net and reflecting the ongoing measurements of poverty.
Temporary assistance for needy families (tanf): Temporary Assistance for Needy Families (TANF) is a federal assistance program in the United States that provides financial aid to low-income families with children, helping them achieve self-sufficiency. TANF was established in 1996, replacing the previous welfare program and shifting the focus from long-term dependency to temporary support and work requirements. This program is closely connected to the concepts of social safety nets and poverty measurements as it plays a significant role in providing financial relief while also influencing the assessment of poverty levels and support needs within families.
