Abstract: In this paper, we investigate the effects of the introduction of 5-
year impact factors. We collect impact factor data for all disciplines available in 
the Journal Citation Reports. For all these categories, we give insights into the 
relationship between the traditional 2-year impact factor and the new 5-year 
impact factor. Our main focus is to investigate whether the traditionally low 
impact factors for statistics journals improve with this new measure. The 
results show that the statistics discipline indeed benefits from the 5-year 
window, that is, the impact factor increases. This appears to be true for most 
disciplines, although the statistics discipline ranks among the top 15 (out of 
171) disciplines in this respect.
