Table 2 Percentage of discrepancy by decile between area-based and household-level income measures

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

Note: In Best-case scenario, non-registered households are assigned a hypothetical household-level income decile that is identical to their area-based measure.
