We partially update Grossman's 2005 survey of patterns in mathematical research using a sample of 401 profiles from MathSciNet. The mathematical landscape has changed substantially: single-paper authors have reduced from 43 \% to 32.42 \%, collaboration has intensified, and the giant component of the co-authorship network has grown denser, with median Erd\H{o}s number dropping from 5 to 4. The data reveal the profession as markedly more collaborative, particularly among younger generations, although the tail of high productivity has also grown more extreme.
