This website is for anyone who wants to better understand the “household” in household surveys. Household surveys are the mainstay of micro-level data for developing countries. They are particularly important in resource-poor country settings where data cannot be produced by routine or administrative data systems. They are vital for poverty measurement and there has been an upsurge in the number of household surveys conducted post-1950. The academic literature critiquing the concept of household is rich, has a long history, and is drawn from many disciplines. Relatively little research examines how these critiques could translate into improved household survey data collection and analysis. The majority of the people who use household surveys – for example, policymakers or programme managers – tend not to be aware of the limitations of a household as defined by a survey.
