Economic activity

Mnemonic reference (code): ECOPUK11

Type: Derived variable

Definition: Economic activity relates to whether or not a person aged 16 and over was working or looking for work in the week before census. Rather than a simple indicator of whether or not someone was currently in employment, it provides a measure of whether or not a person was an active participant in the labour market.

Family Reference Person

The Family Reference Person (FRP) is identified by criteria based on the family make up.


  • In a lone parent family it is taken to be the lone parent.
  • In a couple family, the FRP is chosen from the two people in the couple on the basis of their economic activity (in the priority order: full-time job, part-time job, unemployed, retired, other). If both people have the same economic activity, the FRP is identified as the elder of the two or, if they are the same age, the first member of the couple on the form.


A family is defined as a group of people who are either:

  • a married, same-sex civil partnership, or cohabiting couple, with or without child(ren),
  • a lone parent with child(ren),
  • a married, same-sex civil partnership, or cohabiting couple with grandchild(ren) but with no children present from the intervening generation, or
  • a single grandparent with grandchild(ren) but no children present from the intervening generation.
