It will be proved that for any distribution of population over the unit segment with density which is continuous and bounded away from zero, there exists a consecutive partition into countries that is migration-proof, i.e. such that no individual is willing to change his/her country. This was implicitly conjectured by Alesina and Spolaore in the conclusion to their seminal paper (Alesina & Spolaore, 1997). The proof utilizes the celebrated Gale and Nikaido's lemma, which is known from the proof of the existence of competitive Walrasian equilibrium.
