Definition
HH2 refers to the serial number of each households which were not included in the Enumerator's list due to new households after the Listing fieldwork or missing households during the Listing fieldwork which took place before the census. Letters were used to identify unlisted households. For instance if Household number 1 is on the list and a household next to it was not, then Household 1 would still be listed as Household 001 and the new household wouldl be identified as Household 001a. If there were more households in the same place then more letters could be used. This helped the office to locate the new households in the updated listing fieldwork. It also helped the Enumerators to identify the Listed and Unlisted households.
