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.
Identifies the major weaknesses in the current United Nations system and proposes fundamental reforms to address each. This title is also available as Open Access.
This open access book presents a ground-breaking approach to developing micro-foundations for demography and migration studies. It offers a unique and novel methodology for creating empirically grounded agent-based models of international migration – one of the most uncertain population processes and a top-priority policy area. The book discusses in detail the process of building a simulation model of migration, based on a population of intelligent, cognitive agents, their networks and institutions, all interacting with one another. The proposed model-based approach integrates behavioural and social theory with formal modelling, by embedding the interdisciplinary modelling process within a wider inductive framework based on the Bayesian statistical reasoning. Principles of uncertainty quantification are used to devise innovative computer-based simulations, and to learn about modelling the simulated individuals and the way they make decisions. The identified knowledge gaps are subsequently filled with information from dedicated laboratory experiments on cognitive aspects of human decision-making under uncertainty. In this way, the models are built iteratively, from the bottom up, filling an important epistemological gap in migration studies, and social sciences more broadly.
Annotation This title examines both internal and international migration, at the city level and cities of the Global South. The report highlights the growing evidence of potential benefits of all forms of migration and mobility for city growth and development. It showcases innovative ways in which migration and urbanization policies can be better designed for the benefit of migrants and cities.
The increased importance of international migration flows worldwide & the changing nature of this phenomenon has led to a need to improve statistics on international migration. This publication outlines a process by which both the quality & the comparability of statistics may be improved. It also provides a framework for the compilation of statistics on international population movements.
The 2021 edition of International Migration Outlook analyses recent developments in migration movements and the labour market inclusion of immigrants in OECD countries. It also monitors recent policy changes in migration governance and integration in OECD countries.
