Country is a key variable for determining a range of social and economic statistics, including country of birth, country of residence, migration, international trade and balance of payments.
The National Statistics country classification (NSCC), including the definition and coding index, is designed to be the standard harmonised framework used by National Statistics users and producers involved in the collection and processing of country-related statistical data.
The NSCC is based on ISO 3166-1 (the international standard for country codes) and has been adapted to meet the data needs of UK National Statistics' users and producers.
