In total, there is nothing wrong with either data or Stata, just
some misunderstandings of what Stata actually does.

tab name if  HoursPWeek > 90

will give you all observations which are greater than 90, which includes all missing values. Tab "help missing".

You may want to do:
tab name if  HoursPWeek > 90 & HoursPWeek<.

> Another strange thing:
> If I say "tab name" if  HoursPWeek==99.9 there are "no observations" 
> although I can clearly see in the  data, there are some.
