The National Institute of Statistics (NIS), which is part of the Ministry of Planning, is the focal point on statistical matters in Cambodia. The NIS compiles and consolidates statistics provided by decentralized offices and also collects primary data through household and establishment surveys and population, agricultural and economic censuses. Many development partners financially and technically assisted NIS since 1993.
Cambodia has a decentralized statistical structure. There are statistical bureaus and sections within planning and statistics departments of the various Ministries and in the planning and statistical units in the provinces and districts.
