According to this systemic review (:the most objective kind of evidence come from reviews of studies not primary sources:) 1 in 7 schizophrenia patients met criteria for recovery.

A Systematic Review and Meta-analysis of Recovery in Schizophrenia:
Conclusions: Based on the best available data, approximately, 1 in 7 individuals with schizophrenia met our criteria for recovery. Despite major changes in treatment options in recent decades, the proportion of recovered cases has not increased. http://www.medscape.com/viewarticle/814844
This all depends on their definition of recovery, which is a very abstract concept. Is recovery working at a fastfood chain restaurant when they could have been a nobel prize winning writer if that ability was cared for?
And to define recovery you must as well define the ideal citizen. Is recovery being average or ideal? Because average is not something to be proud of and is still ill from my perspective that healthy individuals are self actualized thriving "Eudamonia" individuals. If you are not of the Eudammonia type of well being then you are ill (: if even it is an illness of abstract nature or is of an unknown kind:) and in need of treatment by someone, something, or your self.
