Comparability
Some surveys only record the quarter or season when the survey was carried out. See country-specific sections for further details.
Comparability — South Africa [top]
In 2000, data was collected in February, June and October; therefore, there are only 3 different values for MONTH (2,6,10).
In 2010, the data collection period included three months only: October, November, and December.

In 2009, data were collected during the entire year, but only the quarter during which the data were collected is available to users. Quarters are represented as follows in the data:
2 April-June 2009 = May
3 July-September 2009 = August
4 October-December 2009 = November

For the 1995 survey, the documentation indicates that the survey was fielded in May, though the original data has some reported June diaries. In all cases, MONTH is assigned to May.
In 2005, the survey collected diaries over four separate four week periods that span the second half of one month and the first half of the next month. As we do not have the precise date, the value for the month variable reflects the start month of the period of collection, but only will be the actual month for some diaries, but not for others.
2 20 June - 16 July 2005 = June
3 19 September - 15 October 2005 = September
4 21 November - 17 December 2005 = November
