Equivalisation is a technique in economics in which members of a household receive different weightings.[1] Total household income is then divided by the sum of the weightings to yield a representative income.

OECD equivalence scale[edit]

Also called the "Oxford scale" and the "old OECD scale". Mentioned by the OECD in the 1980s for possible use in countries without an established scale.[2]

  • 1.0 to the first adult;
  • 0.7 to the second and each subsequent person aged 14 and over;
  • 0.5 to each child aged under 14.

OECD-modified scale[edit]

Currently used by Eurostat.[2][3]

  • 1.0 to the first adult;
  • 0.5 to the second and each subsequent person aged 14 and over;
  • 0.3 to each child aged under 14.

Square root scale[edit]

Adopted by more recent OECD publications. The household income is divided by the square root of household size.[2]
