UN Statisticians tooted  their own horns Wednesday, and showed their numerical prowess by scheduling World Statistics Day date on 20.10 2010.  They even made a video that highlights the importance of the “availability of high quality statistics at the national, regional and global levels,”  the “unbiased official statistics” and “objective and accurate information” government statisticians provide (see the video below).
