Findings

  • During the decade beginning in 1997, the number of scientific and technical articles published and number of S&E doctorate holders increased proportionally, resulting in no significant change in the nationwide value of this indicator.
  • The publication rate for academic S&E doctorate holders in states in the top quartile of this indicator was nearly twice as high as for states in the bottom quartile.
  • In the most recent data, the states with the highest values for this indicator were distributed across the nation.
  • The average indicator value for EPSCoR states was considerably lower than the average indicator value for non-EPSCoR states.


Description

The volume of peer-reviewed articles per 1,000 academic S&E doctorate holders is an approximate measure of their contribution to scientific knowledge. Publications are only one measure of academic productivity, which includes trained personnel, patents, and other outputs. A high value on this indicator shows that the S&E faculty in a state's academic institutions are generating a high volume of publications relative to other states. Academic institutions include 2-year colleges, 4-year colleges and universities, medical schools, and university-affiliated research centers. Research is more central to the mission of some of these institutions than others.

Publication counts are based on the number of articles that appear in a set of journals tracked by Thomson Scientific in the Science Citation Index and Social Sciences Citation Index. Academic article output is based on the most recent journal set; data for earlier years may differ slightly from previous publications due to changes in the journal set. Articles with authors from different institutions were counted fractionally. For instance, for a publication with authors at N institutions, each institution would be credited with 1/N of the article.

S&E doctorates include those in computer sciences; mathematics; the biological, agricultural, or environmental life sciences; physical sciences; social sciences; psychology; engineering; and health fields. S&E doctorate data derive from the National Science Foundation's Survey of Doctorate Recipients, which excludes those with doctorates from foreign institutions and those above the age of 75. The Survey of Doctorate Recipients is a sample survey. Estimates for states with smaller populations are generally less precise than estimates for states with larger populations. Data for S&E doctorate holders in academia are presented by employment location regardless of residence.
