DSS/PSI Programme of Research into Low-Income Families, 2001

The <i>DSS/PSI Programme of Research into Low-Income Families</i> (PRILIF) studied low-income families with dependent children. The study was conducted by the Department of Social Security (DSS) (now the Department for Work and Pensions (DWP)), and the Policy Studies Institute (PSI).<br>
<br>
The PRILIF series began in 1991, when a nationally-representative survey of low-income families was undertaken to study the effects of Family Credit on labour market opportunities. The series finished in 2001, and comprised seven waves, deposited at the UK Data Archive (UKDA) in three parts:<ul><li><i>DSS/PSI Programme of Research into Low-Income Families, 1991-1995</i> (held under SN 3977)</li><li><i>DSS/PSI Programme of Research into Low-Income Families, 1996 and 1998</i> (SN 4425)</li><li><i>DSS/PSI Programme of Research into Low-Income Families, 2001</i> (SN 5406)</li></ul>The PRILIF series examined five main policy issues:<ul><li>how lone parents could improve their incomes, combining paid work, benefits and maintenance payments</li><li>the effectiveness of child support</li><li>the failure of some families to claim their benefit entitlement</li><li>the persistent dfficulties experienced by some families, especially the lowest paid couples, in maintaining themselves in paid jobs</li><li>the wider effects of the use of income-tested in-work benefits on incentives to work</li></ul>The main focus of the research was on families on the margins of work and concerned the influence of different sources of income (benefits, maintenance and earnings) on their labour market participation and family welfare.<br>
<br>
A similar survey series, the <i>Families and Children Study</i> (held under SN 4427), is also conducted by the DWP. <br>

《社会保障部/政策研究所低收入家庭研究项目》（PRILIF）旨在研究有受抚养子女的低收入家庭。该研究由社会保障部（Department of Social Security，简称DSS，现为工作和养老金部（Department for Work and Pensions，简称DWP））与政策研究所（Policy Studies Institute，简称PSI）联合开展。

PRILIF系列始于1991年，当时开展了一项全国代表性的低收入家庭调查，旨在研究家庭信贷（Family Credit）对劳动力市场机会的影响。该系列于2001年结束，包含七轮调查，分为三部分存放在英国数据档案库（UK Data Archive，简称UKDA）：
- 《社会保障部/政策研究所低收入家庭研究项目（1991-1995）》（档案编号SN 3977）
- 《社会保障部/政策研究所低收入家庭研究项目（1996及1998）》（档案编号SN 4425）
- 《社会保障部/政策研究所低收入家庭研究项目（2001）》（档案编号SN 5406）

PRILIF系列探讨了五个主要政策问题：
- 单亲父母如何通过结合有偿工作、福利与抚养费提高收入
- 子女抚养的有效性
- 部分家庭未能申领应得福利的问题
- 部分家庭（尤其是收入最低的夫妇）在维持有偿就业方面持续面临的困难
- 基于收入调查的在职福利政策对工作激励的广泛影响

该研究的核心焦点是处于工作边缘的家庭，探讨不同收入来源（福利、抚养费及工资）对其劳动力市场参与度和家庭福祉的影响。

DWP还开展了另一项类似的调查系列——《家庭与儿童研究》（档案编号SN 4427）。
