人口普查交互数据服务 (CIDS) 是一个数据支持单位，为英国研究人员提供访问人口普查办公室生成的交互数据集的权限。这些移民和通勤数据集庞大且复杂，与地区统计不同，因为它们涉及两个地理区域——一个是出发地，另一个是目的地。
WICID 是一个基于网络的软件系统，旨在为 1991 年人口普查的特别移民统计数据 (SMS) 和特别工作场所统计数据 (SWS) 提供用户界面，现已升级，允许人口普查数据的注册用户提取 2001 年交互数据集的子集。其中包括 2001 年 SMS 和 SWS 以及一套新的苏格兰流量特别旅行统计数据 (STS)。数据集与1991年的不同，不仅是因为提供了输出地区、区、区规模的总流量统计，而且消除披露风险的数据调整方法也与1991年不同。
本文分为三个部分。首先，概述了 2001 年的相互作用数据集，并与 1991 年产生的数据进行了比较。总结了与 2001 年地理边界一致的 1981 年和 1991 年数据的重新估计工作，并使用三个不同空间尺度的迁移数据检查了小小区调整方法（SCAM）的效果。其次，我们说明了 WICID 用户界面的开发，该界面合并了 2001 年的数据并添加了一些分析功能。最后，我们举例说明了 WICID 系统可用于支持从 2001 年人口普查中选择选定数据集的分析类型。
The Census Interaction Data Service (CIDS) is a Data Support Unit providing access for researchers in the UK to the interaction data sets that are produced by the Census Offices. These migration and commuting data sets are large and complex, differing from the area statistics by virtue of the fact that they involve two geographies – one of origin and the other of destination.
WICID, the web-based software system developed to provide the user interface to the Special Migration Statistics (SMS) and the Special Workplace Statistics (SWS) from the 1991 Census, has now been upgraded to allow registered users of census data to extract subsets of the 2001 interaction data sets. These include 2001 SMS and SWS as well as a new set of Special Travel Statistics (STS) for flows in Scotland. The data sets are different from those in 1991, not least because aggregate flow counts are available at the scale of output areas, as well as wards and districts, and because the method of data adjustment to eliminate the risk of disclosure is different from that used in 1991.
This paper is in three sections. Firstly, the 2001 interaction data sets are outlined and compared with what was produced in 1991. Work on the re-estimation of 1981 and 1991 data consistent with 2001 geographical boundaries is summarised and the effects of the small cell adjustment method (SCAM) are examined using migration data at three different spatial scales. Secondly, we illustrate the developments of the WICID user interface that have been made to incorporate 2001 data and to add some analytical functionality. Finally, we exemplify the type of analysis that the WICID system can be used to support choosing selected data sets from the 2001 Census.
