About 2.1 million Mexicans are employed as domestic workers, with women accounting for about 90 percent of such employees, and the majority lack employment contracts, are not registered in the social security system and are subjected to discrimination, long work days, poor pay and other forms of abuse, the National Council to Prevent Discrimination, or Conapred, said.
The figures come from a survey of domestic workers that was conducted in association with U.N. Women and the International Labor Organization, or ILO, Conapred said in a report presented to the Senate.
The 2010 National Survey on Discrimination in Mexico, or Enadis, found that 38 percent of domestic workers consider excessive work and low pay the main problems facing them, while 19.3 percent complained of mistreatment and discrimination, among other abuses, as well as the lack of labor rights.
Just 1.5 million of Mexico's 26 million households, according to National Institute of Statistics and Geography, or INEGI, figures, have domestic workers.
Although the households that hire domestic workers tend to have higher incomes, they pay among the lowest wages.
Pay for domestic workers tends to be among the lowest of any occupation, with 43.7 percent of those toiling in this sector earning between $35 and $71.
Some 90 percent of domestic workers lack employment contracts and working conditions are established via a "verbal agreement" with the employer.
Just 6.7 percent of domestic employees are registered with the social security system, the report said.
