See the ‘Reportation of Aliens Chain’ (until 2020) or ‘State of Migration’ (from 2020) for a substantive explanation of the data in this file. See chapter ‘Methodology’ for a number of aspects to be taken into account when interpreting the data. The ‘Reportation of Aliens Chain’ can be downloaded from the site www.rijksoverheid.nl
When interpreting the data, there are a number of aspects that need to be taken into account.
— All numbers are rounded to dozens. Numbers less than 5 are not shown.
— Because the numbers are rounded to dozens, the addition of detail numbers may lead to deviations from, for example, the annual total. In the case of detailed rules with nationalities, the derogation may be significant. For this reason, the main totals are included in the file.
— Each line in the file contains at least a column ‘Total of’ and a number. The ‘Total of’ column shows the content of the number. For example, the line with ‘Year’ in the ‘Total of’ column indicates the annual total. The rows with ‘Year, Month’ in the ‘Total of’ column indicate the total number for each year and month.
— Always use only one ‘total’ per item to avoid double counting.
— The numbers mentioned in the ‘Reportation of Aliens Chain’ serve as a reference framework.
The files are published monthly and contain data for the current year. New files may include corrections for previous months. File for previous years remains available and will no longer be updated.
