In the past few decades, China has undergone enormous political, economic, and demographic changes that have transformed the realities of migration to and from the country. In addition to large flows of emigrants leaving in search of opportunities elsewhere and the persisting, more traditional streams of internal migrants for which China is known, a new trend of immigration to the fast-developing country is emerging. The driving force behind the recent trend of immigration to China — the world's most populous nation — has been the country’s rapid economic growth, compounded by its passage through a demographic transition. The growth of the Chinese labor force is slowing drastically at a time of mounting demand for labor, and this fact has increased pressure on wages and the country’s aging population.
