• The disparity between R1 and R5 did not change over time. The rate ratio of R1 compared to R5<br />
was 1.08 <strong>in</strong> <strong>the</strong> first time period and 1.03 <strong>in</strong> <strong>the</strong> last time period, for a non–statistically significant<br />
decrease. The absolute difference gap <strong>in</strong> dementia rates compar<strong>in</strong>g R1 to R5 was also not statistically<br />
significant, go<strong>in</strong>g from 0.48 <strong>in</strong> T1 to 0.23 <strong>in</strong> T5.<br />
Urban:<br />
• Compar<strong>in</strong>g T1 to T5, dementia prevalence of all urban neighbourhood <strong>in</strong>come qu<strong>in</strong>tile groups<br />
<strong>in</strong>creased over time. Only <strong>in</strong> U3 was <strong>the</strong> <strong>in</strong>crease steady across all time periods; for all o<strong>the</strong>r urban<br />
neighbourhood <strong>in</strong>come qu<strong>in</strong>tiles, <strong>the</strong>re was one (U1 and U5) or two (U2 and U4) periods of decrease,<br />
with an overall <strong>in</strong>crease over time.<br />
• The disparity between U1 and U5 was stable by one measure and <strong>in</strong>creased by ano<strong>the</strong>r measure.<br />
The rate ratio of U1 compared to U5 was 1.25 <strong>in</strong> <strong>the</strong> first time period and 1.28 <strong>in</strong> <strong>the</strong> last time period,<br />
but this <strong>in</strong>crease was not statistically significant. The absolute difference gap <strong>in</strong> dementia prevalence<br />
compar<strong>in</strong>g U1 to U5 statistically significantly <strong>in</strong>creased by 96% over time, from 1.39 more persons<br />
with dementia per 100 residents aged 55 and older <strong>in</strong> U1 compared to U5 <strong>in</strong> <strong>the</strong> first time period<br />
(1984/85–1988/89) to 2.73 more persons with dementia per 100 residents <strong>in</strong> <strong>the</strong> last time period<br />
(2004/05–2008/09).<br />
Lorenz Curves:<br />
Rural over time:<br />
• In T1, 20.0% of persons with dementia were accounted for <strong>in</strong> 19.7% of <strong>the</strong> population <strong>in</strong> <strong>the</strong> lowest<br />
neighbourhood <strong>in</strong>come qu<strong>in</strong>tile group R1, with <strong>the</strong> G<strong>in</strong>i coefficient of 0.010 <strong>in</strong>dicat<strong>in</strong>g no disparity.<br />
• In T5, 17.0% of persons with dementia were accounted for <strong>in</strong> 16.9% of <strong>the</strong> population <strong>in</strong> <strong>the</strong> lowest<br />
neighbourhood <strong>in</strong>come qu<strong>in</strong>tile group R1, with <strong>the</strong> G<strong>in</strong>i coefficient of 0.003 <strong>in</strong>dicat<strong>in</strong>g no disparity<br />
across rural neighbourhood <strong>in</strong>come qu<strong>in</strong>tile groups.<br />
• The G<strong>in</strong>i coefficient decreased from <strong>the</strong> first to <strong>the</strong> last time period, but <strong>the</strong> decrease was not<br />
statistically significant, which <strong>in</strong>dicates no change <strong>in</strong> <strong>in</strong>equality over that time period.<br />
Urban over time:<br />
• In T1, 26.7% of persons with dementia were accounted for <strong>in</strong> 23.1% of <strong>the</strong> population <strong>in</strong> <strong>the</strong> lowest<br />
neighbourhood <strong>in</strong>come qu<strong>in</strong>tile group U1, with <strong>the</strong> G<strong>in</strong>i coefficient of 0.050 <strong>in</strong>dicat<strong>in</strong>g a statistically<br />
significant disparity.<br />
• In T5, 26.1% of persons with dementia were accounted for <strong>in</strong> 20.4% of <strong>the</strong> population <strong>in</strong> <strong>the</strong> lowest<br />
neighbourhood <strong>in</strong>come qu<strong>in</strong>tile group U1, with <strong>the</strong> G<strong>in</strong>i coefficient of 0.056 <strong>in</strong>dicat<strong>in</strong>g a statistically<br />
significant disparity.<br />
• The G<strong>in</strong>i coefficient <strong>in</strong>creased slightly from <strong>the</strong> first to <strong>the</strong> last time period, but <strong>the</strong> change was not<br />
statistically significant, which <strong>in</strong>dicates no change <strong>in</strong> <strong>in</strong>equality over that time period.<br />
Rural compared to urban <strong>in</strong> most recent time period:<br />
• In <strong>the</strong> most recent time period T5, <strong>the</strong>re is a statistically significantly higher G<strong>in</strong>i coefficient <strong>in</strong> urban<br />
compared to rural (0.003 vs. 0.056, p
