title: Dynamics of a disabled population in Morocco.
abstract: BACKGROUND
  The disabled population constitutes a class of people needing special care and necessitating important economic and social effort.
  
  
  METHODS
  In this paper, using specific parameter settings, partial differential equations are used to model the temporal change of the proportion of the disabled population in Morocco.
  
  
  RESULTS
  Combining different forms and values of the parameters, a numerical method is proposed and three scenarios are considered. These forms and values are determined by data fitting and simulation.
  
  
  CONCLUSIONS
  The experiments show clearly the dynamical evolution of the disabled population with time and age according to each scenario.
