The population and housing census is part of an integrated national statistical system, which may include other censuses (for example, agriculture), surveys, registers and administrative files. It provides, at regular intervals, the benchmark for population count at national and local levels. For small geographical areas or sub-populations, it may represent the only source of information for certain social, demographic and economic characteristics. For many countries the census also provides a solid framework to develop sampling frames. This publication represents one of the pillars for data collection on the number and characteristics of the population of a country.

Healthcare providers, consumers, researchers and policy makers are inundated with unmanageable amounts of information, including evidence from healthcare research. It has become impossible for all to have the time and resources to find, appraise and interpret this evidence and incorporate it into healthcare decisions. Cochrane Reviews respond to this challenge by identifying, appraising and synthesizing research-based evidence and presenting it in a standardized format, published in The Cochrane Library (www.thecochranelibrary.com). The Cochrane Handbook for Systematic Reviews of Interventions contains methodological guidance for the preparation and maintenance of Cochrane intervention reviews. Written in a clear and accessible format, it is the essential manual for all those preparing, maintaining and reading Cochrane reviews. Many of the principles and methods described here are appropriate for systematic reviews applied to other types of research and to systematic reviews of interventions undertaken by others. It is hoped therefore that this book will be invaluable to all those who want to understand the role of systematic reviews, critically appraise published reviews or perform reviews themselves.

Land Reform Revisited engages with contemporary debates on land reform and agrarian transformation in South Africa. The volume offers insights into post-apartheid transformation dynamics through the lens of agency and state making. The chapters written by emerging scholars are based on extensive qualitative research and their analysis highlights the ways in which people negotiate and contest land reform realities and politics. By focusing on the diverse meanings of land and competing interpretations of what constitutes success and failure in land reform Brandt and Mkodzongi insist on looking beyond the productivity discourses guiding research and policy making in the field towards an informed view from below. Contributors are: Kezia Batisai, Femke Brandt, Sarah Bruchhausen, Nerhene Davis, Elene Cloete, Tariro Kamuti, Tarminder Kaur, Grasian Mkodzongi, Camalita Naicker, Fani Ncapayi, Mnqobi Ngubane, and Chizuko Sato.
