Note: ^*The incidence of dementia was obtained by multiplying rates at age groups 60–64 to 90 + by the corresponding populations. ^**The incidence of dementia was obtained by first obtaining the population at risk (total population minus persons who already have dementia) then multiplying the incidence rates at age groups 60–64 to 90 + by the corresponding populations at risk. Source: See Table 1 for source of population data. Prevalence and Incidence rates were taken from Alzheimer’s Disease International, 2015. World Alzheimer Report 2015, p. 20 and p. 33. The rates for East Asia were used for China and those for North America were used for USA. For Canada, the prevalence rates were taken from a personal communication with Maëlenn Guerchet of King’s College London dated 1 June 2018, and the incidence rates for North America were used.
