The proportion of well-educated and skilled workers in Jordan is among the highest in the region in sectors such as ICT and industry, due to a relatively modern educational system. This has attracted large foreign investments to Jordan and has enabled the country to export its workforce to Persian Gulf countries. Flows of remittances to Jordan grew rapidly, particularly during the end of the 1970s and 1980s, and remains an important source of external funding. Remittances from Jordanian expatriates were $3.8 billion in 2015, a notable rise in the amount of transfers compared to 2014 where remittances reached over $3.66 billion listing Jordan as fourth largest recipient in the region.
