The Historical Household Budget database is constantly growing, extending to new countries, social groups, time periods, and data sources. So too is the network of researchers growing, comprising economists, historians, statisticians, and anyone else with an interest in developing the methods and interpreting the results of studies based on historical family budgets. We welcome new collaborators with relevant datasets, and are eager for any indications of possible new data sources, no matter how few or seemingly-obscure. Please contact us.
