Abstract | This paper assesses the empirical representativeness of micro-data by comparing two representative household surveys implemented in Malawi, currently the world’s poorest country, in 2010. The comparison of descriptive statistics –mainly concerning household demographics, asset ownership and living conditions– shows considerable similarities in average values despite statistically identifiable differences. Pronounced differences mostly occur when the wording and scope of the survey questions differ suggesting that the way questions are formulated impacts the responses. Multivariate analyses are less representative due to loss of observations. This results in statistical correlations of asset indicators with human capital as represented by child health and education that are susceptible to the (political) objective of the survey; composite indicators of wealth, in turn, promise more representativeness and, hence, more accurate results. Care is required when drawing policy recommendations as they depend on purpose and design of the survey, and are only representative as far as the context of the data collection is reflected. |
