The UNECE Statistical Division no longer maintains a Handbook of Official Statistics in the UNECE Region.
Instead, the United Nations Statistical Division provides information on national statistical systems:
Published by the United Nations Statistical Division, New York.
The Handbook of Statistical Organization, Third Edition: The Operation and Organization of a Statistical Agency deals with the fundamentals of national systems of official statistics: general principles, data collection and respondent policies, principles of organization and management, and dissemination guidelines. The intended audience for the Handbook are both chief statisticians (and their colleagues) and those charged with oversight of the official statistics function.
The Third Edition (ST/ESA/STAT/SER.F/88) is a complete revision of the 1980 edition and is so far available in Arabic, Chinese, English and Spanish. In due course, it will also be issued in French and Russian.
