1) Persons with disabilities refers to persons formally recognised as disabled, with a degree of dissability of  33% or over, according to the procedure for evaluating this established in the RD 1971/1999 and modified by the RD 1856/2009.

 2) Physical and other: impairments of the osteoarticular, neuromuscular, cardiovascular, immune, respiratory, digestive, metabolic and endocrine systems
 Intellectual
 Mental
 Sensory: impairments of the visual and hearing systems

 3) When the box is marked with a '-' sign before the data, it indicates that the number of sample  observations is between 100 and 500, so the figure is subject to great variability.

 4) (..)  = data not available.
