The datafile is in format csv. In Excel, the csv file cannot be entirely open and display incorrectly two variables: 1. household size: category 3-4 is displayed and coded as 3rd of April; and 2. level of employment: category 1-39 is displayed and coded as January 1939. However, the right codes (1. 3-4, and 2. 1-39) are available in the csv file. This problem does not occur while opening the csv file with another application such as Stata or as plain text.
