Economic migration and birthrate gaps fed Serb demographic fear in Kosovo
Evidence
The new constitution enraged Serb nationalists. After World War II, the Albanian population in Kosovo had increased in proportion to the Serbian population. Kosovo was the poorest region of Yugoslavia; some Serbs migrated to better employment and living opportunities available for them elsewhere, while Albanians tended to remain in an area where their language was spoken. Impoverished Kosovo Albanians also had one of the highest birthrates in Europe, and the Serbs, already a minority in Kosovo, began to look at the large Albanian families with demographic fear. — Michael A.
