[P13c-d were asked of persons who worked for pay or profit or family gain.]
P13c How many days did (name) work for pay or profit or family gain? _ _
P13d How many hours did (name) work for pay or profit or family gain? (If 99 hours or more code 99) _ _
P13d How many hours did (name) work for pay or profit or family gain?
In order not to confuse the respondent, it would be better to find out the number of hours worked each day for the period. The total number of hours could be obtained by adding the hours together for the number of days worked.
If the person has a fixed number of hours worked each day then multiply the answer in P13c (i.e. no. of days worked) by the number of hours worked each day.
Note if the person worked 99 hours or more code 99 and mark.
