Language in Zambia is part of the Survey of Language Use and Language Teaching in Eastern Africa, for which extensive research was carried out by an interdisciplinary group of international and local scholars. The survey, which also covered Ethiopia, Kenya, Tanzania and Uganda, represents the most comprehensive sociolinguistic study made in this region in modern times. It provides the basic linguistic data necessary to policy-makers, administrators, educators, and others with responsibility for the formulation and execution of language policy.
