An article on the Migration Information Source web site takes at in depth look at the statistics concerning emigration from El Salvador and remittances sent home. One impact is globalization:
In fact, it can be easily argued that migration is El Salvador's principal gateway to globalization. And this is due not only to the volume of remittances but also to a myriad of other economic activities that have increased because of migration.
According to data from the US Federal Communications Commission, telephone calls between the United States and El Salvador rose 570 percent from 99.9 million minutes in 1992 to 669 million minutes in 2002 as families made use of increased access to land lines as well as cell phone expansion to keep in touch.
Information from the US Bureau of Transport Statistics shows that air traffic between El Salvador and the United States increased exponentially from 123,846 passengers in 1990 to more than 1.3 million in 2004. The principal cities of destination (Los Angeles, Washington, DC, Houston, New York, and San Francisco) coincide with the largest concentrations of Salvadorans in the United States.
Linked to air traffic is ethnic tourism. Salvadorans who live outside the country and come to visit stay longer and spend more per day than tourists of other nationalities. According to the Ministry of Tourism, on average, Salvadoran visitors stay 19 days and spend $97 per day while other tourists stay only eight days and spend $87 per day.
No wonder, then, that the immigration debate in the US is followed so closely in El Salvador.
