There are about 245 million migrants worldwide – around 3% of the world population. Roughly one-fifth are tertiary educated. Middle-income countries have a smaller proportion of immigrants than high-income countries (about 1% versus 12%). But for a number of middle-income countries with more immigrants than others, there is uneasiness about relying on unskilled foreigners as they strive to leap from low-wage labor and imitation to high-skilled labor and innovation. There are palpable concerns in Malaysia, for example, with some 2.1 million registered immigrants – about 7% of its population - and likely over 1 million undocumented immigrants. Things reached a crescendo early last year when all new hiring of unskilled foreign workers was suspended as the Malaysian government re-evaluated the management and need for foreign workers. The freeze was subsequently lifted for select sectors amid complaints of labor shortages.
