push factor
In migration, any adverse factor which causes movement away from the place of residence. Examples of pushes include: famine, changes in land tenure (the Highland Clearances, 1790-1850), political persecution (Tamil separatists, Sri Lanka, 1989), mechanization which made agricultural workers redundant (but See rural depopulation) and which made factory products cheaper than those of cottage industry. Relatively few migrations are spurred by push factors alone.
