A/HRC/11/7/Add.2 page 12 and nationality. As such, they may go largely unprotected and remain especially vulnerable to abuse. The Special Rapporteur received reports of wealthier Mexican families employing “servants” from Guatemala, El Salvador and Honduras. Vague estimates state that, for example, there may be 1,000 El Salvadoran female domestic workers in Mexico City alone and hundreds of Guatemalan domestic workers in the Tapachula area, many of them below the age of 18 and from indigenous communities. Central American domestic workers reportedly earn significantly lower wages than their Mexican counterparts. 37. But these numbers are not substantiated with recent data, and the precise locations of most of these workers are unknown. The situation of domestic workers remains of particular concern because of its wholly unregulated nature and therefore warrants further research. Federal law to a certain extent protects workers in the domestic sphere, but labour authorities seem to be doing little to monitor the situation of domestic workers or implement the obligations placed on employers. Health and education standards seem to be disregarded. C. Migrant children, including unaccompanied minors, and child labour 38. Migrant children including labourers (predominantly in the agricultural industries) and unaccompanied minors, is an issue of increasing concern in Mexico and a stated priority of the Government of Mexico. DIF estimates that there were 21,366 unaccompanied minor and adolescent migrants attended to in 2007. INM estimates there were a total of 17,558 Mexican unaccompanied minors (internal migrants) registered in the country in 2007. Both the northern and southern border regions pose an extremely high risk for children and adolescents. Traffickers and smugglers (polleros or coyotes) - many of them operators of gangs - take minors across the border, sometimes in order to reunite them with family members who have emigrated and sometimes to hand them over to exploiters. Many of these children are in need of international protection, since they are fleeing not only poverty but also maras, criminal groups, violence and abandonment by their families and society. They are returned to countries that lack adequate protection networks and where due attention is not given to their future reintegration; this exposes them to new risks of trafficking and exploitation. 1. Migrant children, including unaccompanied minors 39. Many migrant children are repatriated/deported back to their countries of origin. Of those deported in 2007, 47.46 per cent were Guatemalans, 36.85 per cent were Hondurans, 15.56 per cent were Salvadoran and 0.01 per cent were Nicaraguan. A total of 24 minors (15 boys, 9 girls) applied for asylum in Tapachula, representing 10.71 per cent of total asylum-seekers. The majority of these children were accompanied by their parents. None of the children were recognized as refugees in Tapachula. 40. DIF is the principal governmental organization dealing with children; through 32 offices of DIF at the state level, it attempts to build capacity at the local level through child protection programmes, a network of 29 shelters and an expansive system of information-sharing on individual cases. It develops national child protection policies, as well as intervention and rehabilitation strategies for child victims, and provides shelter to migrant families and
