Coverage1976-ongoing
Scope As the ratio of people over sixty-five continues to rise, understanding the basic mechanisms of aging and age-related diseases has become a matter of urgent necessity. "Gerontology" responds to this need by drawing experimental contributions from diverse medical, biological, behavioural and technological disciplines to provide a primary source of high quality papers covering all aspects of aging in man and animals. Recent research on the clinical problems of aging and the practical applications of laboratory results is also included to support the fundamental goals of extending active life and enhancing its quality. Informative reviews and an open Debate Section for stimulating, speculative articles carry strong reader approval.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

Cites per Doc

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years.
