During a speech at Budapest's 3rd Demographic Summit, Orbán warned that the biggest problem Europe faced was demographic suicide.
"Why is this the case? It's most certainly not because of some sickness of Christian civilization – after all, the number of Christians are rising all around the world. This is a sickness of Europe in general," he said.
The Prime Minister said that the solution was not to import vast numbers of migrants, asserting, "We must never accept population exchange."
According to Orbán, the remedy should be to ensure that families were financially rewarded for having children, not punished.
"We win only if we can build a system where those who bear children live significantly better than if they hadn't started a family," he said.
