The Journal Impact Factor is defined as citations to the journal in the JCR year to items published in the previous two years, divided by the total number of scholarly items, also known as citable items, (these comprise articles and reviews) published in the journal in the previous two years.
Impact factor data has a strong influence on the scientific community, affecting decisions on where to publish, whom to promote or hire, the success of grant applications, and even salary bonuses.
Only journals listed in the Science Citation Index Expanded (SCIE) and Social Sciences Citation Index (SSCI) receive an Impact Factor.
