We describe the scientific research about human aging in Brazil from the 4.1 version of the Executive Committee of the Research Groups in Brazil (2002) of the Scientifical and Technological Development National Council (CNPq). The criterion to identify the studied groups was the one of, at least, the development of a research line related to the human aging, and the search in the data base was done from key words related to the human aging. There were one hundred and forty-four groups identified, two hundred and nine research lines, and five hundred and eleven researchers. We discussed the fields of knowledge in which these groups are enclosed, the period in which they apeeared, and their geographical and institutional distribution.
