What is disability-adjusted life expectancy?
disability-adjusted life expectancy is A modification of conventional life expectancy to account for time lived with disability. It is the number of healthy years of life that can be expected on average in a given population. It is generally calculated at birth, but estimates can also be prepared at other ages. It adjusts the expectation of years of life for the loss on account of disability, using explicit weights for different health states.
