In 2010, 34% of ruralmigrantworkers left their factory jobs to move back home, according to the most recent data available from the Rural-Urban Migration in China and Indonesia project at Australian National University.
It used to be that migrantworkers would come from the more rural areas of Brazil during harvest season and essentially live at the mill for the season, using the old slash-and-burn technique to harvest the sugarcane.
The World Bank says that rural wages (outside farms) fell by almost a fifth between 2007 and 2009 as migrantworkers fled to their villages in search of jobs.
