All numbers are unweighted. All numbers refer to the 2008/2009 wave, with exception for percent died, which refers to the period of 2008/2009-2011/2012
In order to see the percentage distributions of death, frailty, and socioeconomic vulnerability by age, in this table age is measured by age groups. In the regression analyses, age is measured by single year of age
^a The score of frailty index ranges from 0 (the healthiest) to 1 (the worst) with the number in parentheses indicating the average number of deficits ranging from 0 (the healthiest) to 39 (the worst)
^b The score of the socioeconomic vulnerability index ranges from 0 (the least vulnerable or the highest SES) to 1 (the most vulnerable or the lowest SES) with the number in parentheses indicating the average number of vulnerable socioeconomic conditions ranging from 0 (highest SES) to 6 (lowest SES)
