4.2.9 Household Number (HHN)
Each household within a housing unit will be given a one-digit serial number - 1,2,3, etc. If the housing unit is vacant write '0' and then shade the appropriate space. This will indicate that no one was living there at the time of enumeration. You will then get the housing particulars for the housing unit. If the Housing Unit is occupied, but you do not contact any household member at that particular housing unit, leave the column for HHN blank. For a non residential building, record zero for HiIN and shade accordingly.
