Goal Of The Study:
The number of people with dementia (PwD) in Germany is expected to grow beyond 2 million until 2030. The present analysis aims to estimate (a) the number of PwD in 10 years and b) the percentage change until 2030, and c) the proportion of the population in 2030, each on the county level.
Methods:
For all n = 401 counties in Germany estimates are provided on how many PwD are living there in 2030, how the share of POwD in the population is and how both figures change between 2018 and 2030. The data is illustrated graphically.
Result:
In 2030 it is expected that approx. 2.170.000 PwD above age 65 are living in Germany. The development differs strongly between counties ranging between no change up to an increase of 50 %. The proportion of PwD in the population is 2.61 % nationally, but varies by county between 1.75 % and 4,18 %.
Conclusion:
Regional prognoses are helpful to plan health care and support for the coming 10 years at an early stage and evidence-based. The population of PwD is growing as important group in all counties in Germany.
