Statistics on Language impaired preschoolers

[Adele Proctor]

1.Does anyone have references for demographics or any statistical data on
incidence or prevalence of language impairment/language disorders in
preschool children?
2. Also, any info on language disorders/impirment in preschool children
from multicultural backgrounds.
Thanks in advance for your recommendations, Adele
