title: Migration as a means of population control.
abstract: Abstract   The more crowded West Indian islands lose citizens each year through emigration, and they are small enough for an appreciable relief of population pressure to be thereby afforded. Each year some of the inhabitants of Java move to Sumatra and elsewhere under official sponsorship, part of the rationale for the policy being the relief of population pressure; a recent definitive study covers the movement in detail.
