Mean and standard deviation of the frailty index in SAGE countries by sex, age, education and wealth.

Note: Estimates are weighted using the standard population distribution based on the WHO World Standard. For educational attainment we used a standard coding based on the 1997 International Standard Classification of Education ISCED-97 (UNESCO [16]). Income quintiles in SAGE countries were generated from the household ownership of durable goods, dwelling characteristics and access to services. Countries sorted in increasing order by the mean of the frailty index.
