The Expenditure and Food Survey is now the Living Costs and Food Survey.〔(Living Costs and Food Survey ), UK Data Service, retrieved 8 November 2013〕 The Expenditure and Food Survey (EFS) is a survey conducted by the Office for National Statistics (ONS) and the Department for Environment, Food and Rural Affairs (DEFRA) which collects data about private household expenditure and food consumption in Great Britain. == History == From 1957 until 2001, there were two different surveys conducted each year: the Family Expenditure Survey (FES) and the National Food Survey (NFS). These two surveys were combined in the Expenditure and Food Survey (EFS) which completely replaced the former series. The survey is conducted by the Office for National Statistics (ONS), the DEFRA sponsors the food data.〔(Living Costs and Food Survey catalogue description ), UK Data Service, retrieved 8 November 2013〕 The design of the survey is based on that of the FES but there have been some changes, notably with the introduction of the European Standard Classification of Individual Consumption by Purpose (COICOP). Another change has occurred with the use of a new processing software, SPSS, which has affected the structure of the datasets.〔(Introductory Guide to the Living Costs & Food and Expenditure & Food Surveys, (PDF) ), Economic and Social Data Service, retrieved 8 November 2013 〕 Additionally, the EFS has changed from a financial year based system to a calendar year based one in 2006; from January 2008, the EFS became known as the Living Costs and Food (LCF) module of the Integrated Household Survey (IHS).〔(Living Costs and Food Survey catalogue description ), UK Data Service, retrieved 8 November 2013〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Expenditure and Food Survey」の詳細全文を読む スポンサード リンク
