- Twenty-eight percent of all workers in March 1996 were low-wage workers, which is consistent with other studies. While this share remained relatively stable throughout the panel, the share of low-wage workers decreased slightly (from 28 percent to 25 percent) through the mid- to late-1990s.
- Females, African Americans and Hispanics, single parents with children, individuals with health limitations, recent public assistance recipients, and workers in poor households were disproportionately likely to be low-wage workers.
- Low-wage job and employment spells were typically short. During the study period, the median length of low-wage job spells was about four months. About 80 percent ended within a year, and more than 90 percent ended within two years.
- There was substantial job mobility among low-wage workers. Many low-wage workers experienced upward mobility (mainly into “medium-wage” jobs) and wage growth during the study period. Still, many workers simply moved in and out of the low-wage labor market during the course of the panel.
- Upward mobility was more common for those low-wage workers who began the period with better quality jobs (somewhat higher wages, health benefits available, full-time hours) and for those who switched jobs (relative to those still in their starting job).
- Low-wage workers experienced considerable wage growth during the study period. Average wage increases for low-wage workers were about 25 percent over a three-year period after they started their jobs, or a real wage increase of nearly 8 percent per year. Female workers had lower wages than male workers throughout the follow-up period, but wage growth was similar by gender, as shown in the figure below.
