Northern Ireland Family Expenditure Survey, 1979

<P>Abstract copyright UK Data Service and data collection copyright owner.</P>The <i>Northern Ireland Family Expenditure Survey</i> (NIFES) was conducted in Northern Ireland from 1967-1998, and was the counterpart to the <i>Family Expenditure Survey</i> (FES), which was conducted annually in Great Britain from 1957-2001 (see under GN 33057). The FES/NIFES provided reliable data on expenditure and income in relation to household characteristics. The results of the survey show how expenditure patterns of different kinds of households vary, and the extent to which individual members of a household contribute to the household income. Although originally commissioned to provide expenditure details for the calculation of weights for the Retail Price Index, the FES/NIFES collected much additional information was also collected on the characteristics of co-operating households and the incomes of their members. It thus became a multi-purpose survey, and provided a unique fund of important economic and social data. <br>
<br>
From 1968 the Great Britain FES incorporated a sample drawn from the NIFES to become the UK FES. The FES was replaced in 2001 by a new survey series, the <i>Expenditure and Food Survey</i> (EFS) (see under GN 33334), covering the whole of the UK. The EFS is an amalgamation of the previous <i>National Food Survey</i> (NFS) (see under GN 33071) and UK FES.<br>
<br><br><B>Main Topics</B>:<BR>Household Schedule:<br>
This schedule was taken at the main interview. Information for most of the questions was obtained from the head of household or housewife, but certain questions of a more individual character were put to every spender aged 15 or over (or 16 or over from 1973 onwards). Until the introduction of the community charge, information on rateable value and rate poundage was obtained from the appropriate local authority, as was information on whether the address was within a smokeless zone. Information was collected about the household, the sex and age of each member, and also details about the type and size of the household accommodation. The main part of the questionnaire related to expenditure both of a household and individual nature, but the questions were mainly confined to expenses of a recurring nature, e.g.:<ul><li>Household: housing costs, payment to Gas and Electricity Boards and companies, telephone charges, licences and television rental</li><li>Individual: motor vehicles, season tickets for transport, life and accident insurances, payments through a bank, instalments, refund of expenses by employer, expenditure claimed by self-employed persons as business expenses for tax purposes, welfare foods, education grants and fees</li></ul>Income Schedule:<br>
Data were collected for each household spender. Apart from page 1, the schedule was concerned with income, National Insurance contributions and income tax. Income of a child not classed as a spender was obtained from one or other of his parents and entered on the parent's questionnaire. Information collected included: employment status and recent absences from work, earnings of an employee, self-employed earnings, National Insurance contributions, pensions and other regular allowances, occasional benefits - social security benefits and other types, investment income, miscellaneous earnings of a 'once-only' character, tax paid directly to Inland Revenue or refunded, income of a child.<br>
<br>
Diary Records<br>
Each diary covered fourteen days. Each household member aged 15 or over (or 16 or over from 1973 onwards) was asked to record all expenditure made during the 14 days.<br>
<br>
The NIFES was identical to the UK FES and therefore used the same questionnaires and documentation. However, starting in 1988, a voluntary question on religious denomination was asked of those aged 16 and over in Northern Ireland.<br>

北爱尔兰家庭支出调查（Northern Ireland Family Expenditure Survey, NIFES）于1967年至1998年在北爱尔兰开展，是对应1957年至2001年大不列颠地区每年开展的家庭支出调查（Family Expenditure Survey, FES）的配套调查项目（详见GN 33057）。FES与NIFES提供了与家庭特征相关的支出与收入可靠数据，其结果揭示了不同类型家庭的支出模式差异，以及家庭个体成员对家庭收入的贡献程度。尽管该调查最初仅为计算零售物价指数权重而委托开展，但最终还额外收集了合作受访家庭的特征及其成员收入的大量信息，由此成为一项多用途调查，并形成了独特且重要的经济与社会数据宝库。

1968年起，大不列颠地区的FES纳入了来自NIFES的样本，进而形成覆盖全英国的FES。2001年，FES被新的调查系列支出与食品调查（Expenditure and Food Survey, EFS）取代（详见GN 33334），该调查覆盖全英国。EFS是原全国食品调查（National Food Survey, NFS）（详见GN 33071）与英国FES的整合项目。

主要研究主题：
家庭问卷：
该问卷于主访谈环节发放。多数问题的信息由户主或家庭主妇提供，但针对15岁及以上（1973年起调整为16岁及以上）的每位实际开支者设置了部分个性化问题。在引入社区收费制度前，有关应评税价值及税率的信息，以及该住址是否处于无烟区的信息，均通过相应地方当局获取。调查收集了家庭整体情况、每位家庭成员的性别与年龄，以及家庭住宿的类型与规模等信息。问卷的核心内容涵盖家庭与个体两类支出，但主要聚焦于经常性开支，例如：
- 家庭类：住房成本、燃气与电力公司缴费、电话费、执照费及电视租赁费
- 个体类：机动车、交通季票、人寿与意外保险、银行缴费、分期付款、雇主报销的费用、个体经营者为税务申报用途列支的营业支出、福利食品、教育补助金与学费

收入问卷：
针对每位家庭实际开支者收集数据。除第一页外，问卷主要围绕收入、国民保险缴费及个人所得税展开。未被归类为实际开支者的儿童的收入信息由其父母一方提供，并录入父母的问卷中。收集的信息包括：就业状况与近期缺勤情况、雇员薪资、个体经营收入、国民保险缴费、养老金及其他定期津贴、临时性福利（社会保障福利及其他类型福利）、投资收益、一次性性质的杂项收入、直接向国内税务局缴纳或退还的税款、儿童收入。

日记记录
每份日记的记录周期为14天。要求每位15岁及以上（1973年起调整为16岁及以上）的家庭成员记录其在14天内的所有支出。

NIFES与英国FES完全一致，因此采用相同的问卷与文档材料。但自1988年起，北爱尔兰地区16岁及以上的受访者被额外询问了关于宗教教派的自愿性问题。
