In a review of Tizard and Phoenix's (1993) study, Sinclair drew attention to the paucity of official statistical information on children of mixed parentage, including the omission of a 'mixed' category in the 1991 Census classification. This article documents the limitations of that classification (which unsatisfactorily accommodated the needs of some 230 000 persons who identified their mixed origins in write‐in descriptions), examines the only official sources of information that can be used to estimate the number of children of mixed parentage, including the Samples of Anonymised Records and the Labour Force Survey statistics, and assesses the current policy needs for such information. Finally, the provision for people of 'mixed' ethnic/cultural background in the 2001 Census is discussed. Copyright © 2000 John Wiley & Sons, Ltd.

Data collection is one of the main operations performed in Wireless Sensor Networks (WSNs). Even if several interesting approaches on data collection have been proposed during the last decade, it remains a research focus in full swing with a number of important challenges. Indeed, the continuous reduction in sensor size and cost, the variety of sensors available on the market, and the tremendous advances in wireless communication technology have potentially broadened the impact of WSNs. The range of application of WSNs now extends from health to the military field through home automation, environmental monitoring and tracking, as well as other areas of human activity. Moreover, the expansion of the Internet of Things (IoT) has resulted in an important amount of heterogeneous data that are produced at an exponential rate. Furthermore, these data are of interest to both industry and in research. This fact makes their collection and analysis imperative for many purposes. In view of the characteristics of these data, we believe that very large-scale and heterogeneous WSNs can be very useful for collecting and processing these Big Data. However, the scaling up of WSNs presents several challenges that are of interest in both network architecture to be proposed, and the design of data-routing protocols. This paper reviews the background and state of the art of Big Data collection in Large-Scale WSNs (LS-WSNs), compares and discusses on challenges of Big Data collection in LS-WSNs, and proposes possible directions for the future.
