This chapter analyses the economic assimilation of Asians in the United States. It explains the incidence of unemployment, part-time employment, full-time employment with low pay, and job mismatch to provide a better picture of the employment situation of Asians in the United States. The effects of disability status are generally positive for most groups in determining the economic forms of underemployment. Disability status has no effect on the likelihood of job mismatch. Industrial sector effects mostly reveal the preponderance of unemployment among those in the manufacturing sector, as shown by the mostly significant negative relationship of the different industries to unemployment, particularly of women. Household head status decreases the likelihood of all the types of underemployment. It decreases unemployment and working in poverty for all groups, decreases part-time work for all but Vietnamese men and Indian women, and decreases job mismatch for white and Filipino women and for all but Indian men.
