Some of the entries in this dictionary describe variables on the Census unit record file. Each variable has a mnemonic, e.g. LLDD for Landlord Type. Mnemonics are a convenient shorthand method of describing variables on the Census unit record file. Mnemonics are often used by clients when specifying customised tables.
It is essential that Census data users know whether the variable relates to a dwelling, a family or a person. The last character of the mnemonic is therefore important: it is a D for dwelling, an F for family, or a P for person.
Complete classifications for Census variables are listed in Section 1, 2006 Census Classifications.
