This report discusses the contribution of immigrants to Maryland's workforce, trends in the workforce between 2000 and 2006, and recommendations for educating and training immigrant workers. Rapid growth in the number and share of immigrant workers in the state do not appear to have come at the expense of native-born workers, who saw their labor force participation grow over this six year period. Maryland's immigrant workers are unusually diverse, highly educated and work in key skilled industries such as healthcare, information technology and the sciences.
