From the The 2019 World Report:

At the core of the 2019 report are the results of a global survey, commissioned by ADI and undertaken by the London School of Economics and Political Science (LSE). Almost 70,000 people globally engaged with the survey, making it the biggest of its kind ever undertaken.

LSE developed the survey to target four key groups:

(1) people living with dementia,    (2) careers,            (3) healthcare  practitioners and    (4) the general public, with analysis being provided in three categories: knowledge, attitudes and behaviour.

In the survey analysis we highlight the behavioural element first, giving prominence to the voices and experiences of people living with dementia as direct assessment of actual behaviour is central to discrimination and is the closest representation of the true impact of stigma on people living with dementia.
