# Stuart Levenbach The [[Chief Statistician of the United States]] since January 2026, succeeding Mark Calabria after roughly six months in the post. The seat turned over twice between June 2025 and January 2026. The office administers [[Statistical Policy Directive No. 1]] and [[Statistical Policy Directive No. 15]] and chairs the Interagency Council on Statistical Policy. It is not Senate-confirmed and carries no fixed term, which is the structural point recorded in [[Federal Statistical System Tree]]: the independence of the federal statistical system rests on directives issued from an office that any administration can fill at will. ## See also - [[Chief Statistician of the United States]] · [[Office of Management and Budget]] · [[Federal Statistical System Tree]] - [[Statistical Policy Directive No. 15]] · [[How a Census Question Is Added or Removed]]
