Why do some cases have missing person identifiers in the GHS 2005?

PID is the person identifier variable and in the GHS it is missing for cases conducted in the first quarter. The GHS 2005 file is drawn from two sources. A new design was introduced with a larger sample and a calendar year cycle in the second quarter, this data is therefore available for quarters 2-4. Data for the first quarter is drawn from the GHS 04/05 in order to generate a file which relates to the full calendar year. Cases for the first quarter do not have the person identifier variable PID. Furthermore, it is not possible to uniquely identify individuals by combining information on hserial and persno, as duplicates may occur between the 05 and 04/05 data. However, it is possible to uniquely identify cases using a combination of hserial, persno and sampqtr.
