Age group
“The age profile of rated researchers in 2006 indicates that the majority of rated
researchers are within the 40-49 (32,9%) and 50-59 (36,2%) age categories. It is
interesting to note that the 2002 data from the Centre for Research on Science
and Technology (CREST) at Stellenbosch University indicate a similar pattern in
these two categories for the ISI-accredited journals and South African (SA) journals
approved by the Department of Education.
However, the 2002 CREST data show that young researchers (30-39 age
category) published more articles in ISI or SA-accredited journals (18,8%), while
only 11,5% obtained a valid rating in 2006.
The percentage of A-, B- and C-rated researchers within the age categories
did not change significantly from 2003 to 2006.”
