Research and Development Outputs

Academic Science and Engineering Article Output per 1,000 S&E Doctorate Holders in Academia



Findings

  • Between 2001 and 2010, the number of scientific and engineering articles published by academia increased from 141,000 to 154,000 and the number of S&E doctorate holders in academia increased from 251,000 to 300,000.
  • In 2010, the value of this indicator across the states ranged from 255 to 705 S&E articles per 1,000 S&E doctorate holders in academia.
  • 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. The average indicator value for Experimental Program to Stimulate Competitive Research (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, trademarks, copyrights, 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.

Publication counts are based on the number of articles that appear in a set of journals tracked by Thomson Reuters 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 the biological, agricultural, or environmental life sciences; computer, physical, and social sciences; mathematics; psychology; engineering; and health fields. S&E doctorate data are estimates and exclude those with doctorates from foreign institutions and those older than the age of 75. Estimates for states with smaller populations of S&E doctorate holders are generally less precise than estimates for states with larger populations. Data for S&E doctorate holders in academia are presented by employment location.
