This brief summarizes the contribution of immigrants to Maryland's workforce and trends in the workforce between 2000 and 2006. Maryland's immigrant workers are unusually highly educated and work in key skilled industries such as healthcare, information technology and the sciences. However, there are also large numbers of immigrant workers with low educational attainment and English proficiencythey largely work in construction, agriculture, and services. Education, English language, and job training programs if properly tailored to immigrants' and employers' needs could potentially raise the incomes of immigrant workers and increase their tax contributions to the state.
