From: On the validity of area-based income measures to proxy household income

Area-based Measure Group None One Two Three Four Five Six Seven Eight Nine
Actual household-level income All 14.9 22.5 18.5 14.5 10.8 7.7 5.3 3.3 1.8 0.7
  Non-seniors 14.9 21.8 18.2 14.7 11.2 7.9 5.4 3.4 1.8 0.7
  Seniors 15.6 23.9 19.1 14.4 10.4 7.2 4.7 2.7 1.4 0.6
Best-case scenario All 33.4 18.3 14.4 11.4 8.3 5.4 4.1 2.6 1.4 0.7
  Non-seniors 37.8 16.0 13.3 10.7 8.2 5.8 3.9 2.5 1.3 0.5
  Seniors 20.2 22.7 18.0 13.6 9.8 6.8 4.4 2.6 1.3 0.6
  1. Note: In Best-case scenario, non-registered households are assigned a hypothetical household-level income decile that is identical to their area-based measure.
