Household surveys provide essential socioeconomic data across South Asia, using standardized methods that enable evidence-based program design and impact measurement.
This workshop progresses from data preparation through analysis to visualization, with special focus on South Asian contexts and a case study on gender analysis in Bihar.
Household survey data features a multi-level structure with interconnected datasets, unique identification systems, and temporal dimensions that require careful handling during analysis.
South Asian surveys vary in focus and methodology, with DHS examining health indicators, MICS assessing children's welfare, LSMS measuring poverty and living standards, and NSS tracking country-specific socioeconomic data.
Proper data preparation involves understanding survey design, accessing raw materials, organizing files systematically, and documenting all decisions throughout the process.
Address four critical structural data issues in South Asian surveys: missing data patterns, coding inconsistencies, skip pattern errors, and character encoding problems.
A systematic approach to identifying and correcting data errors through outlier detection, range verification, consistency validation, and duplicate removal, with special consideration for South Asian survey contexts.
Variable creation transforms raw survey data into standardized, comparable measures through format standardization, composite development, and index construction—essential for meaningful analysis across South Asian contexts.
Sampling weights adjust for unequal selection probabilities in complex survey designs, ensuring accurate representation of diverse populations in South Asian surveys.
South Asian surveys require careful standardization of units across multiple dimensions—land measurements, currency values, seasonal variations, and household sizes—to enable meaningful comparisons and accurate analysis.
Data collection timing and methodological choices significantly impact South Asian survey results, with recall periods, seasonal variations, and data collection approaches all affecting the reliability and interpretation of findings.
Standardization of demographic variables is essential for consistent analysis across diverse South Asian datasets, requiring careful harmonization of age, gender, household, education, occupation, and ethnicity data.
Thorough documentation of variables, cleaning decisions, transformations, and version control ensures research transparency and reproducibility.
Dataset merging requires methodical approaches to connect records across different sources while maintaining data integrity. Key strategies include linking individuals to households, matching geographical identifiers, and reconciling time periods.
Effective descriptive analysis requires attention to central tendency and dispersion measures, full distribution examination, and group-based disaggregation to reveal patterns in South Asian data that summary statistics alone might obscure.
Effective tabulation methods organize data to reveal meaningful patterns and relationships. Each technique has specific applications and requires careful interpretation, particularly when analyzing South Asian survey data.
Effective analysis of categorical data requires proper proportion calculations, appropriate visualization techniques, meaningful subgroup comparisons, and careful consideration of relative composition methods.
Distribution analysis in South Asian data reveals socioeconomic patterns through visualization tools, commonly showing skewed economic variables and requiring contextual outlier interpretation.
Correlation analysis reveals relationships between variables in South Asian household data, requiring careful interpretation of coefficients, visualization through matrices and scatter plots, and appropriate significance testing.
Education increases wages for all groups, but gender wage gaps persist across all educational levels. Statistical methods like t-tests and ANOVA help confirm the significance of these differences.
Agricultural labor hours show consistent gender differences and strong seasonal variations, peaking during planting and harvest seasons. These patterns are critical for proper data interpretation.
Geographic analysis reveals spatial patterns across administrative levels, rural-urban divides, and regional clusters, with important implications for data quality and interpretation in development research.
Inequality analysis employs metrics like the Gini coefficient and Lorenz curves to measure economic disparities, while examining group differences by gender, caste, and religion reveals systematic disadvantages. Quintile analysis further identifies gradients in socioeconomic outcomes across wealth segments.
Household dynamics in South Asia reveal complex patterns in resource allocation, decision-making, time usage, and consumption that often vary by gender and household structure.
Effective data visualization requires selecting appropriate chart types, designing with accessibility in mind, incorporating cultural context, and avoiding common misinterpretation pitfalls.
Master fundamental chart types to effectively visualize different data: bar charts for categories, line graphs for trends, scatter plots for relationships, and box plots for distributions.





Advanced visualizations transform complex data relationships into accessible insights. Heat maps reveal correlations, radar charts compare multiple dimensions, small multiples facilitate group comparisons, and interactive tools enable personalized exploration.
Statistical significance communication requires visual tools like confidence intervals and error bars, along with clear significance indicators. Proper consideration of sampling weights is essential when analyzing complex survey designs.
Gender analysis in South Asia reveals persistent educational gaps, complex decision-making patterns, and disproportionate unpaid care work for women, with disparities varying across intersections of caste, religion, and economic status.



Health indicators in South Asia must be interpreted within cultural, economic, and social contexts to understand complex factors affecting healthcare outcomes and utilization patterns.
Educational indicators in South Asia show persistent gender gaps that widen at higher education levels, with disparities in enrollment, attendance patterns, learning outcomes, and economic returns.
Women's economic empowerment in South Asia requires looking beyond standard metrics to understand participation, ownership, and agency across multiple dimensions.
Effective data interpretation requires examining results through multiple lenses: comparative benchmarks, historical trends, policy influences, cultural contexts, and qualitative insights.
Effective data analysis requires transforming observations into actionable insights by identifying gaps, forming hypotheses, connecting indicators, and developing program implications.
Proxy reporting in South Asian surveys creates systematic bias when one household member (usually male) answers for others. This practice distorts data on women's economic activities, health issues, and experiences, particularly for sensitive topics. Mitigation requires multiple respondent interviews and privacy protocols.
South Asian surveys face significant underreporting across multiple domains, from women's economic contributions to sensitive social issues. Actual prevalence of reported phenomena may be substantially higher than captured in standard surveys due to methodological limitations and cultural factors.
Sampling weights are essential statistical adjustments that correct for oversampling of certain populations. Without proper weighting, survey data can lead to significant estimation errors and invalid conclusions about South Asian populations.
Cultural contexts significantly impact South Asian survey data through social desirability bias, gender norms, caste/class dynamics, and interviewer characteristics. These factors can systematically distort responses on sensitive topics, requiring specialized methodological approaches.
South Asian survey data faces critical access barriers including documentation gaps, language inconsistencies, necessary privacy protections, and evolving regulatory frameworks that researchers must navigate carefully.
Data quality significantly declines as distance from district headquarters increases, creating risks that vulnerable remote populations are represented by less reliable data. New methodologies are being developed to address this geographical data quality gap.
Modern survey approaches leverage digital tools, satellite imagery, open-source mapping, and observational techniques to overcome traditional data collection challenges in diverse environments, particularly benefiting hard-to-reach populations.
Research on sensitive topics requires specialized protocols, indirect questioning techniques, and careful interviewer selection to ensure accurate data collection while protecting respondent privacy and safety.
Combining quantitative and qualitative methods strengthens research by providing both breadth and depth, while engaging communities ensures findings reflect local context and knowledge.
South Asian poverty measurement utilizes diverse methodologies including asset-based, consumption, income, participatory, and multidimensional approaches, each offering unique insights into different aspects of deprivation.
A comprehensive gender analysis examining time-use patterns and asset ownership in Bihar, India's economically challenged state, using a 2023-2024 survey of 2,500 households across 8 districts.
The Bihar dataset required extensive cleaning due to gender-biased missing data, inconsistent land measurements across districts, high proxy reporting for women respondents, and time-use data with varying recall periods. These challenges highlight both methodological issues and substantive gender patterns in data collection.
Rural Bihar women face severe time poverty, spending 11+ hours daily on unpaid household, agricultural, and care work, with minimal leisure time compared to men—creating barriers to economic empowerment.
Gender disparities in Bihar's time-use patterns reveal women's fragmented, multitasking schedules compared to men's concentrated activities. Women's domestic workload remains consistent despite seasonal agricultural demands, with education and caste further influencing time allocation patterns.




Significant gender disparities exist in formal asset ownership across Bihar, with men's ownership rates 3-9 times higher than women's across land, housing, and financial assets. Livestock shows the smallest gender gap due to targeted government programs.
Women in Bihar experience significant disparities between asset access and formal ownership/control, creating economic vulnerability despite their substantial contributions to household production.
Despite high formal banking access for women in Bihar, significant gaps exist between account ownership and independent usage, with digital financial services and credit access showing substantial gender disparities.
Asset ownership significantly influences how women allocate their time, with secure property rights, technology access, financial inclusion, and mobility assets all correlating with distinct time-use patterns.
Education strongly correlates with improved economic outcomes for women across multiple dimensions, with particularly dramatic effects on financial inclusion.
Analysis reveals distinct patterns across household types with female-headed households showing higher decision authority but greater time constraints, younger households demonstrating more progressive asset sharing, technology access improving time efficiency, and collective participation enhancing women's economic empowerment.
Statistical tests confirm significant gender differences in time use and asset control. Education impacts financial inclusion more than caste, while program participation shows strong correlation with empowerment indicators.
Research reveals four critical inquiries: disconnect between women's asset ownership and control, gender-based time allocation patterns, unexplained district-level variations, and concerns about proxy-reported data reliability.
Program interventions should address five key areas: strengthening women's asset control beyond documentation, implementing time-saving technologies, enhancing financial capability, targeting educational thresholds, and engaging male household members for sustainable impact.
