Notes:
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) 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.

 3) (..)  = data not available.
