The primary work activity of 37 percent of scientists and engineers with disabilities is research and development, compared to 38 percent of those without disabilities. Twenty-five percent of scientists and engineers with disabilities and 21 percent of those without disabilities are in management or administration. Among those with supervisory responsibilities, persons with and without disabilities have about the same number of subordinates. The average number of subordinates for persons with disabilities is 12 and the average number of subordinates for persons without disabilities is 11. Salaries M edian salaries of scientists and engineers with disabilities do not differ substantially from median salaries for those without disabilities.
Salaries differ little within fields and age groups as well.
The data on persons with disabilities in science and engineering are seriously limited for several reasons. Different sets of data have used different definitions and thus are not totally comparable. The third limitation on information on persons with disabilities gathered from surveys is that it often is obtained from self-reported responses. Typically, respondents are asked if they have a disability and to specify what kind of disability it is. Resulting data, therefore, reflect individual decisions to self-identify, not objective measures.
