International migration: what is measured (and what is not)

Among the events contributing to population dynamics, international migration is the most difficult to capture. Most countries do not have the tools to produce regular statistics. Definitions and measurement methods may vary from country to country. Since the early 2000s, international organizations such as the United Nations and the European Union have been promoting more standardized approaches that allow comparisons to be made. Whatever the indicator used, France appears to be one of the countries with the lowest immigration in Western Europe.
