HI,
I WOULD LIKE TO KNOW HOW TO COMPUTE A VARIABLE INDICATING THE NUMBER OF BIRTHS PER WOMAN IN THE LAST 4 YEAR (48 MONTHS. THE DHS DATA SET ONLY INDICATE BIRHS IN THE LAST 1 AND 5 YEARS. A SYNTAX WOULD BE VERY HELPFUL.

Kind Regards

George

Here is a response from one of our Senior Data Processing Specialists, Lady Ortiz, that should answer your question.

Assuming that you are using the "Births data", this data set has all the children ever born from women interviewed. The variable B3 is the date of birth of each child in months, and V008 is the date of the interview, also in months. Subtracting B3 from V008 (V008 B3), will give you the age in months for each child. After doing that, you can filter your data to select only children 0-47 months of age. If you are using SPSS, the Aggregate command can be used to count the number of children 0-47months of age per woman.

In SPSS the syntax will look like:

COMPUTE AGE4 = ( V008 B3).
SELECT IF (AGE4 >= 0 & AGE4 <= 47).
