Venn diagram of overlap between four indicators of ill health, n = 7196. The circles denote each of the four indicators and are proportional in size to the sample captured by each; the intersections are not proportional. Colour legend: Red = Chronic Conditions, Purple = Activity Limitations, Green = Severe Health Difficulty, Blue = Elevated Service Use. Not shown on the diagram is the intersection between activity limitations and elevated service use (n = 53) and the intersection between chronic conditions and severe health difficulties (n = 116).
