The proportion of workers classified as working poor was highest for those employed in service occupations; at 11.2 percent, their rate was twice the average for all workers.
Individuals who had worked in natural resources, construction, and maintenance occupations also had an above-average working-poor rate—7.3 percent.
The data were collected in the 2005 Annual Social and Economic Supplement to the Current Population Survey. For more information see A Profile of the Working Poor, 2004, Report 994 (PDF 87K).
