Estimated economic burden of ADRDs by country groups through 2050, trillions of 2020 constant US$ (Model 1).

Note: Data were available for 168 countries covering more than 99% of the world population. Country income group classifications are from the World Bank (2020 definition). Disease burden was projected based on constant 2010-2019 growth rate (Model 1). Estimates were based on income elasticity values of E=1 for HICs and E=1.5 for LMICs, and adjusted to 2020 constant US$ using consumer price index data from the U.S. Bureau of Labor Statistics. All future year estimates were discounted at a 3% annual discount rate. LIC: Low-income countries; LMIC: Lower-middle income countries; UMIC: Upper-middle income countries; HIC: High-income countries; T: Trillion.
