Almost half of the total number of migrant workers in the world today are women. While women have always migrated as accompanying spouses and family members, contemporary migration dynamics have shown a considerable increase in the number of women migrating independently to pursue opportunities of their own. On a global scale, a significant number of women migrant workers are employed in low skilled occupations but they are also present in skilled welfare and social professions such as health, education and social services (traditionally female-dominated domains). Among these, most women migrant workers are found in the nursing sector.
