Estimation of the Healthy Life Expectancy in Italy Through a Simple Model Based on Mortality Rate

We use an advanced methodology based on the mortality rate of a population to explore the healthy life expectancy (HALE) estimates of the World Health Organization (WHO) from the Global Burden of Disease Study. First we calculate the loss of healthy life year estimator (LHLY) and then the healthy life expectancy (HLE). We use the full life tables from the Human Mortality Database (HMD). Our estimates are compared with the HALE estimates for Italy and other countries. Another direct estimation based on the mx and qx quantities provided from the Life Tables is also introduced and tested.
