Hi,
I have few things that I wonder in the DHS dataset.
Question 1.
Responding first to Friedrich Hueblers answer 2009-06-22.
I tried as you said inorder to get the age of mother and age of father. But
those variables seems weird to me. Some of the values indicate 2, which in
impossible. None of mothers or fathers' age can actually be 2 years. There are
variables indicating partners age (v730)and mothers' age (v447a). I just don't
understand why the two variables created according to the following command:
by hhid: gen mage = hv105[hv112]
by hhid: gen fage = hv105[hv114]
doesn't give the same value in years as in the v730 and v447a. Normally this
should be the case, or is it?
Question 2. - Disposable household income variable
I would like to create a variable for disposable household income. This variable
doesn't exit in the DHS datasample but I would like to use a proxy variable that
is available in the data. The suggested proxy variables are;
.wealth index hv270 (indicates 1-5 level, where 1 is the poorest and 5 is richest.
.respondens'currently working v714 (the respondent consist of only women which
then will not indicate a good proxy for household income)
Other potentially proxy variables are:
. partners occupation v704 v705
. respondents occupation v716 v717
I don't know which variable that can in an efficient and in a consistent way
show the disposable household income variable.
question 3. - Nr of siblings
I would like to create, if possible nr of siblings for children under 5 (my
dependent variable)
How can I create this variable. I have looked if there is variable for nr of
siblings. However, looking at the data sample closely the variables
. Nr of household member h009
. Nr of children under five years h014
My reasoing for creation of nr of siblings is the following: looking closely at
these two variables shows the following:
Ex: in row nr5. the h009 denotes 5 and h014 denotes 2. Thus, this particular
household, incorporates 5 household members with 2 children under five. The one
member that is left, who is this person? Is it sibling as I am assuming or
another family member such as a relative. Further more, I don't know if both
parents are alive in the household. In order to check if both parents are alive
I take on this method.
sort hhid hvidx
by hhid: gen mother = hv010[hv112]
by hhid: gen father = hv011[hv114]
The hv010 and hv011 represents nr of eligible women and nr of eligible men in
the household. The hv112 and hv114 denotes, mother and fathers line nr
respectively. Nevertheless, there are two other variables sh11 and sh13 which
also indicates mother and fathers line nr. Does it matter which one I use?
Somehow, it doesn't give me the desired results. Instead I try to combine with
the variables
. mothers' alive sh10
. fathers' alive sh12
This I just check by edit command. In the end how can I verfiy if the one member
is actually a sibling? Because this is the variable that I am looking for.
So, if someone can enlighten me in these three question. I would be happy.
Best regards
Tharshini
