Asylum reception in figures (COA)

How many people live in COA reception, how many arrive and leave each month, which countries they come from and how many already have a residence permit and are waiting for a home. The Ministry of Asylum and Migration publishes these migration chain figures monthly as CSV on data.overheid.nl, one file per year. National figures: not per municipality or per location.

What you can build with it1

DashboardAsylum reception dashboard: national and per municipalityA dashboard that shows how many people live in COA reception since 2016, how many arrive and leave, and how many reception places each municipality has, also per 1,000 residents.3 sourcesGetting started

What can you do with it?3 ideas

Getting started

Reception over the years

Line up occupancy per month, from the low point in June 2018 (20,010 residents) to more than 83,000 in 2026.

Getting started

Waiting for a home

The number of permit holders in reception shows how many people may already stay but have no home yet: a measure of the pressure on municipalities.

Advanced

Intake versus outflow

Compare intake and outflow per month and see when reception grows or shrinks; link outflow to housebuilding per municipality.

How to process it3 steps

Pick the yearly file
Each dataset (occupancy, intake, outflow) has one CSV per year. The list of addresses is in the data.overheid.nl dataset record.
```
https://data.overheid.nl/data/api/3/action/package_show?id=immigratie-coa-opvang-en-onderdak-bezetting
```
Read the encoding correctly
Semicolons as separator. The files from 2016 to 2023 and 2026 are in Windows encoding (cp1252), those of 2024 and 2025 in UTF-8. Try UTF-8 first, otherwise cp1252.
Pick one breakdown
The column 'Totaal van' says which breakdown a row is: 'Jaar, Maand' is the monthly total, 'Jaar, Maand, Vergunninghouder' splits by status, 'Jaar, Maand, Land van herkomst' by country. Use one per count, otherwise you count twice. *Alle* means: all values together.

Interesting combinations

jaar en maand, land van herkomst

Asylum applications and reception

CBS table 83102NED counts asylum applications per month and nationality; put it next to the intake into reception.

Combine with CBS StatLine

provincie en gemeente

Where are the places?

The monthly figures are national. For the spread across the country: capacity per location from our harvest of coa.nl.

Combine with COA reception locations

Similar sources

C
COA reception locations
Capacity per location, not the number of residents.

What to watch out for

Rounded to tens
All figures are rounded to tens and counts below 5 are not shown. Adding up details (per country) therefore gives a different number than the total: use the total rows.
Not per municipality or location
The open files are national. The COA's own figure pages are images. Per location there is only the capacity on coa.nl (see COA reception locations).
Corrections afterwards
A new monthly file can correct earlier months of the same year. Fetch the whole yearly file again.

Filtering tested

No filters: whole annual files. Pick rows yourself with the 'Totaal van' column (which breakdown) and *Alle* in the other columns.

Limits and pitfalls

No key and no limit; plain file downloads. No Last-Modified header, but Accept-Ranges. tested
Encoding varies per year: cp1252 (Windows) up to 2023 and again in 2026, UTF-8 in 2024 and 2025. Semicolon separator, CRLF line endings. tested
Each line is one breakdown (occupancy 2026: 26 kinds). Never sum across all lines: pick one 'Totaal van'. The monthly total is 'Jaar, Maand' (September 2026: 83,150). tested
Rounded to tens, counts under 5 omitted: the sum over countries is not the total. experience
The JSON files next to the CSVs are chart settings (dataStore, settings.activeChart), not data. tested
The file list is also in data.overheid.nl's CKAN API (package_show), but robots.txt disallows /data/. The dataset page and the files under /sites/default/files/ are allowed. tested
