The Romanian statistical agency was called the Central Directorate of Statistics from 1951-1989. From 1989-1998 it held the title National Commission for Statistics. The name changed again in 1998 to National Institute of Statistics and Economic Studies and to National Institute of Statistics in 2001. Information is from a Wikipedia article on the National Institute of Statistics in Romania which provides the history of the organization from 1859 to the present.
