          The head of household is usually taken to be the first person         
          entered on the Census form, provided they are a) 16 years or          
          older and b) usually resident.                                        
          Omits households with 12+ persons and households headed by an 
          under-16 year old. Also omits those not economically active within 
          the ten year period prior to the 1991 Census.                                                  
DHDCLASS is derived from SOCHEAD, which gives a value of 0 to all non-household heads or 'heads' aged under 16, and gives to heads of household aged 16 or above a value which is equivalent to the value of that person'ssocial class. DHDCLASS selects the highest value of SOCHEAD across each household, which will correspond to the social class of the household head.
