The present chapter addresses some issues on survey design and sample design for household budget surveys. The focus is on surveys in developing countries. Problems of measuring consumption and income are discussed in some detail in section B. Section C contains a discussion on some crucial sample design issues, for example, stratification, and sample allocation in space (geographical) and in time (over the full season). Section D provides a description of the Lao Expenditure and Consumption Survey 1997/98 (LECS-2). In section E, some of the experiences from LECS-2 are discussed.
