Nirina,

If you are unable to send msg to the list, you can check if you set
your email to "plain text". Statalist refuses emails in rich format
without giving any error msgs, which happened to me before as well.

My thoughts on the questions.

(1a) IPUMS-USA creates some routines that construct the family
interrelationship variables. You can check it out.

http://usa.ipums.org/usa/chapter5/chapter5.shtml

(1b) I think your expectation that husband and wife will give the same
answer is wrong. They are not necessarily the first partner for each
other.

(3) I guess that you have three variables: var2, sex, year of birth.
If so, I think you should calculate mean of each category by female
and year of birth, which will be more meaningful.

(4) Follow Nick's suggestion.

Hope it helps.
