How much did you eat yesterday? And how much did you spend? On what food products exactly? And what about last week? These types of questions can be very hard for anyone to answer, yet most analyses of poverty, food security, and nutrition are based on data collected using different variants of these questions. Therefore, ensuring that the way data on food consumption and expenditures is collected yields accurate information is essential for monitoring and understanding the welfare of a society and progress toward key development goals.
