Why do minority populations often grow faster than majorities? States in dyadic conflict with a minority whose population growth exceeds that of the majority are prone to protective measures to bolster the majority’s grip on power. Under conditions of ethnic control, however, such measures appear to precipitate higher fertility rates among the minority. Christian Leuprecht develops the logic of a demographic security dilemma to account for this pervasive puzzle.
