ftpt
Notes from the GHS
Question
I am using the GHS from 1983 onwards and I face a problem
with the full/part time work distinction. For years 1985 and 1986 there is
no information if the individual works full time or part time. In contrast
to years before and after (i.e. in 1984 the variable that distinguishes between
full time and part time work is ftpa and the variable is in the person84.dta
module, for year 1987 the corresponding variable is ftpa and is in person87.dta
module). I know that the distinction between full time and part time work
can de done though the working hours per week, however it is a mystery to
me why this distinction is not made for these two years. I have been looking
in the other modules for these years as well. There is information on the
distinction between part/full time work for the head of household, or for
the working status in the previous year, but not for the individual at the
year of the survey. Would you please have a look and advise me appropriately?
Answer
As ftpta is a derived variable I'm
not shocked or overly worried at its absence from certain years. I've rummaged
around and found the algorithm for it for 93 - so my best advice is to apply
this rule to your own data to obtain comparable data.
if (worklwk = 1) (I'm not sure what
this is - presume simply a filter on working?)
if(teach = 1) if (workhrs > 0 and <26) = p/t
if (workhrs < 25 and < 99) = f/t
elseif (workhrs = 0 or na) = na hours else
if (workhrs > 0 and < 31) = p/t
if (workhrs > 30 and < 99) = f/t
elseif (workhrs= 0 or na) = na hours
elseif (worklwk = 3, 4, 5, or 6) = -9
