New Delhi, June 13 -- Union Home Minister Amit Shah on Saturday directed a high-level committee on demographic change to undertake a detailed study of shifts in population structure in border districts and conduct field assessments in areas witnessing significant demographic changes, officials said.

Chairing a meeting of the committee, Shah asked its members to visit border regions, metropolitan cities and industrial towns to examine changes in population patterns caused by illegal migration and other factors.
