๐ How Rare Are You in Romania?
๐ท๐ด Genetic Landscape of Romania
Romania's genetic heritage is uniquely Daco-Roman โ a blend of ancient Dacian (Thracian) peoples and Roman colonizers, with later Slavic, Hungarian, Turkic, and German additions. The Carpathian Mountains created natural genetic barriers, preserving distinct regional profiles. Transylvania shows Hungarian and Saxon German genetic influence, while Moldavia has more Eastern European markers. Romania has one of Europe's most balanced eye color distributions, with no single color dominating.
Old provinces, not a single country, explain most of what follows. Wallachia and Moldavia spent centuries as tributary principalities facing the Ottomans, while Transylvania lay under Hungarian and then Habsburg rule, which is why its villages still carry Saxon fortified churches and Szekely Hungarian speech. Banat, further west, was resettled in the eighteenth century with Swabian German farmers invited onto land recovered from the Ottomans. In the far north, Maramureศ kept its wooden churches, its dialect and its local marriage patterns behind the mountains long after the lowlands opened up. And in the Danube Delta, Lipovan villages founded by Russian Old Believers fleeing persecution still fish the channels, speaking a Russian their ancestors carried in with them.
๐ The column marked “information not available”
Romania's 2021 census table of resident population by ethnicity names twenty-one ethnicities, adds a column for any other ethnicity, and then adds one more: Informație nedisponibilă, information not available. In the ROMANIA row it holds 2,484,926 people out of 19,053,815, roughly 13 in every 100 counted. The statistics office says what is in it. Ethnicity, mother tongue and religion were recorded from what each person declared, so the column covers both people who refused to declare those three things and people whose census record was put together indirectly from administrative sources instead of from a form they filled in. Under article 22 of the census ordinance, the individual records of about a million people were completed that way, by statistical imputation from statistical and administrative sources, because no filled-in form existed for them.
The gap is also new. The same office publishes ethnicity counts for each of the eight censuses in that series back to 1930, and the column reads 5,052 in 1930, 452 in 1977 and 1,941 in 2002 — then 1,236,810 in 2011 and 2,484,926 in 2021. In two census rounds a rounding error became an eighth of the country. Worth keeping in mind while reading the percentages below: a national figure is only as complete as the record it is drawn from.

🧮 Calculate Your Rarity in Romania
Pick your eye colour, hair colour and blood type. The calculator uses Romania's own figures from the tables above, not world averages.
This is an estimate, not a measurement. It multiplies three national frequencies as if they were independent, and they are not: eye and hair colour share pigmentation genes, so a combination that tends to run together, such as blue eyes with blonde hair, is more common than the multiplication suggests, while one that rarely does, such as blue eyes with black hair, is rarer. Blood type is independent of both. The frequencies are national averages from public datasets — see Data Sources.
That number describes the body you were born with. Fraeon, our other site, does the same arithmetic for the part you chose: the films, series, games, books, anime and manga you have actually finished. Start your log →
๐บ๏ธ Where the national average describes almost nobody
In the 2021 census, 1,002,151 residents are recorded as Hungarian. What share that is depends on what you divide by. Against all 19,053,815 residents it comes to 5.3 per cent; the statistics office divides instead by the 16,568,889 people who declared an ethnicity at all, and publishes 6.0 per cent. Open the same table at county level and the national number stops meaning much either way. In Harghita, 232,157 of 291,950 residents are recorded as Hungarian — close to 80 per cent of everyone counted, and 85.7 per cent of those who declared. In Covasna it is 133,444 of 200,042. Neighbouring Mureș splits: 252,400 Romanian against 165,014 Hungarian out of 518,193.
The holes in the record are regional too. Bucharest municipality returns 438,876 of its 1,716,961 residents in the information-not-available column, about a quarter of the city, against 20,949 of 291,950 in Harghita, about 7 per cent. Since that column covers both people who refused to declare and people whose record was assembled from administrative sources, the census ended up with very different amounts of the same information depending on where it was asked. Every percentage on this page is one national number standing in for a country that does not hold still across its counties.
โจ๏ธ Two ways to spell the same surname
Romanian writes ș and ț with a comma under the letter. The Unicode Standard gives the Romanian form its own code point — U+0219, s with comma below — and keeps it separate from the Turkish s with cedilla at U+015F, which carries a little hook instead. The Standard says that in modern usage the preferred representation of Romanian text is the comma-below letter while Turkish data uses the cedilla, and that the s and t letters with these two marks pose particular interpretation issues for Turkish and Romanian data.
Then it concedes the mess. Because of the legacy character sets, it says, “a large amount of Romanian data will contain” the cedilla letter or the corresponding code point 0xBA in the older ISO 8859-2 encoding. So a Romanian surname exists in the world's databases as two different strings, and the Standard has to tell software to treat the two as equivalent when processing Romanian data. Whether two people share a name can come down to which byte a keyboard produced.
โญ Rare Facts About Romania
Behind the four numbers at the top
One of them is institutional. The 19,053,815 is the definitive 2021 census figure from the Institutul Național de Statistică, and it counts usual residents — people whose home had been in Romania for at least twelve months, or who arrived meaning to stay that long — not citizens. The rest are not institutional. Romania's census collects ethnicity, mother tongue and religion, and nothing about appearance, so the eye, hair, blood-type and height figures here have no Romanian record behind them; treat them as estimates compiled from public datasets.
