We have a grad student who has been using the Food Expenditure Survey for expenditure at restaurants by country of birth. This variable has been dropped for the 2001 survey. Is there any other data source for this type of information? He has collected data to 1996 and now cannot find more current data.
Income division (responsible for Food Expenditures) confirmed that you are correct, there is nothing after 1996 on this and they are not aware of any other resources to be able to assist you.
