Wealth and Assets Survey, Waves 1-5, 2006-2016

The <i>Wealth and Assets Survey</i> (WAS) is a longitudinal survey, which aims to address gaps identified in data about the economic well-being of households by gathering information on level of assets, savings and debt; saving for retirement; how wealth is distributed among households or individuals; and factors that affect financial planning. Private households in Great Britain were sampled for the survey (meaning that people in residential institutions, such as retirement homes, nursing homes, prisons, barracks or university halls of residence, and also homeless people were not included).<br>
<br>
The WAS commenced in July 2006, with a first wave of interviews carried out over two years, to June 2008. Interviews were achieved with 30,595 households at Wave 1. Those households were approached again for a Wave 2 interview between July 2008 and June 2010, and 20,170 households took part. Wave 3 covered July 2010 - June 2012, Wave 4 covered July 2012 - June 2014 and Wave 5 covered July 2014 - June 2016. Revisions to previous waves' data mean that small differences may occur between originally published estimates and estimates from the datasets held by the UK Data Service. Data are revised on a wave by wave basis, as a result of backwards imputation from the current wave's data. These revisions are due to improvements in the imputation methodology.<br>
<br>
A Secure Access version of the WAS, subject to more stringent access conditions, is available under SN 6709; it contains more detailed geographic variables than the EUL version. Users are advised to download the EUL version first (SN 7215) to see if it is suitable for their needs, before considering making an application for the Secure Access version.<br>

<i>Latest edition information:</i><br>For the 8th edition (October 2018),  the Wave 1-3 Person and Household data files have been redeposited. Additional variables requested by users applied consistently across the three waves have been added. These include year, month, dvageband (dvage but banded for disclosive age groups) and GOR. The OAC variable has been removed from Wave 3 with the addition of GOR.

<i>财富与资产调查</i>（WAS）是一项纵向调查，旨在通过收集以下信息填补家庭经济福祉数据中的已知空白：资产、储蓄与债务水平；退休储蓄情况；家庭或个人间的财富分配方式；以及影响财务规划的因素。英国的私人家庭被纳入本次调查的抽样范围（即居住在养老机构、疗养院、监狱、兵营或大学宿舍等住宿机构的人员及无家可归者均未包含在内）。<br>
<br>
WAS于2006年7月启动，第一波访谈历时两年（至2008年6月）完成。第一波共访谈了30,595户家庭。2008年7月至2010年6月期间，这些家庭被再次邀请参与第二波访谈，共有20,170户家庭参与。第三波覆盖2010年7月至2012年6月，第四波为2012年7月至2014年6月，第五波为2014年7月至2016年6月。对前几波数据的修订可能导致最初发布的估计值与英国数据服务局（UK Data Service）持有的数据集估计值存在微小差异。数据修订按波次进行，基于当前波次数据的反向插补（backwards imputation）。这些修订源于插补方法（imputation methodology）的改进。<br>
<br>
WAS的安全访问版本（Secure Access version）受更严格的访问条件限制，可通过SN 6709获取；其包含的地理变量比EUL版本更详细。建议用户先下载EUL版本（SN7215），确认是否满足需求后，再考虑申请安全访问版本。<br>
