    This paper proposes a methodology for the estimation of the number of people that show a severe disability and are dependent, using data coming from the Italian National Survey on Health conditions and Appeal to Medicare. Dependency is treated as a latent trait hidden behind a set of items that survey difficulties in movements and in accomplishing everyday tasks (Activities of daily living). Latent class models are used to classify the population according to different levels of disability. The analysis provides a good classification using four classes. Looking at posterior probabilities, people belonging to each class may be labelled as being without disability, with light disability, with some dependence, with severe disability (dependent). The survey provides reliable estimates at regional – NUTS 2 – level. Estimating the amount of population within each latent class at sub-regional level, e.g. sanitary districts, requires small area estimation techniques. To this end, a multinomial unit level model is used with individual level covariates.
