๐ How Rare Are You in Colombia?
๐จ๐ด Genetic Landscape of Colombia
Colombia is one of the most tri-ethnic nations in the Americas โ a blend of Indigenous, Spanish, and African ancestry that varies dramatically by region. The Andean highlands show more Indigenous and European traits, the Pacific coast is predominantly Afro-Colombian, and the Caribbean coast is the most mixed. Colombia has one of the world's highest O blood type frequencies (62% combined), reflecting strong Indigenous genetic roots. The country's biodiversity extends to its people.
Two communities sit outside that three-way frame altogether. San Basilio de Palenque, in the low hills inland from Cartagena, was founded by people who escaped slavery and won recognition of their freedom from the Spanish crown around the turn of the eighteenth century; its residents still speak Palenquero, a Spanish-lexicon creole shot through with Kikongo and spoken nowhere else on earth. Out in the Caribbean, nearer to Nicaragua than to the mainland, the Raizal people of San Andrรฉs and Providencia are Protestant, speak an English-based creole and descend from British settlers and the people they enslaved rather than from Spaniards. Both were absorbed by borders drawn far from where they lived, and both kept languages the mainland never spoke.
โ๏ธ The census count that lost in court
Every percentage on this page is a fraction, and the bottom of it is whatever the state managed to count. Colombia has a court judgment about exactly that. In Sentencia T-276 de 2022, dated 1 August 2022, the Constitutional Court set two censuses side by side: in 2005, 4,311,757 people identified themselves as Black, Afro-Colombian, Raizal or Palenquera — 10.3% of the population. The 2018 census returned 2,982,224, or 6%. A fall of 30.8%.
DANE said at the time that the result was “no es consistente con la dinámica demográfica” — not consistent with the demographic pattern the previous census had found — and afterwards used its 2018 quality-of-life survey to set the official census figure at 4,671,160 people, 9.34% of the population. The Court put the 30.8% drop down to a set of factors in the census operation itself: errors in running it and in putting the questions, particularly the ethnic self-recognition question; enumerators altering the self-recognition answer or wrongly assigning the “no ethnic group” code; under-counting of people in a household; and omission in areas not visited or only partly covered.
It ordered DANE to study those causes across the last three censuses, with the communities and the academics who have worked on the problem, and to publish what it learned; to discuss with Afro-Colombian organisations whether the next quality-of-life survey should pilot a complementary heterorecognition criterion alongside self-recognition; and to finish a preparation plan for the next census covering, among other things, ethnic-racial training for enumerators and supervisors and the identification of territories that are hard to reach for logistical, weather or public-order reasons. It refused one thing the claimants asked for — making the quality-of-life survey representative at municipal level — on the ground that the result would still be an estimate.

🧮 Calculate Your Rarity in Colombia
Pick your eye colour, hair colour and blood type. The calculator uses Colombia'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 →
๐ Seven per cent nationally, seventy-four in Chocó
DANE's technical bulletin of 21 August 2025 reports the 2024 Encuesta Nacional de Calidad de Vida: about 3,737,000 people, 7.1% of the country, self-identify as Black, Afro-descendant, Raizal or Palenquera. DANE prints its own error bar next to it — the figure sits somewhere between 3,537,000 and 3,937,000, or 6.7% to 7.5% — because the survey asked 85,387 households, 228,688 people, rather than everyone.
Split by department, that 7.1% stops describing anywhere. In Chocó, 74.4% of the department's own population self-identifies that way; in San Andrés 57.3%, Nariño 26.8%, Bolívar 20.9%, Valle del Cauca 17.6%, Cauca 15.5%, La Guajira 14.6%. The same table counts about 42,000 people who identify as Raizal of the San Andrés, Providencia and Santa Catalina archipelago and about 12,000 as Palenquero of San Basilio, and flags both as imprecise, with coefficients of variation above 15%. A national average is an arithmetic result, not a description of anybody.
๐ฒ When a draw decides the order of your surnames
A Colombian birth record carries two surnames. Until 4 August 2021 the father's came first by law; that day Ley 2129 de 2021 repealed Ley 54 de 1989 and rewrote Article 53 of Decreto 1260 de 1970. A birth is now registered with the mother's first surname and the father's first surname “en el orden que decidan de común acuerdo” — in whatever order the parents agree. The same rule covers children born inside and outside marriage, adopted children, and children of de facto unions and same-sex couples.
The tie-break is the unusual part. If the parents cannot agree, the official who keeps the birth register settles it “mediante sorteo” — by drawing lots — under a procedure the Registraduría Nacional del Estado Civil was given six months to write. The Constitutional Court forced the change: on 5 November 2019, in Sentencia C-519 de 2019, it struck the words “seguido del” out of the 1989 law, but deferred the effect by two legislatures, to 20 June 2022, so that Congress could write the replacement. Congress got there first. Which surname comes first decides which one a register files you under — see name rarity.
โญ Rare Facts About Colombia
Which of these Colombian numbers are official
The institutional figures on this page come from DANE, Colombia's national statistics office. The population total of about 52 million matches DANE's population projections, which are built on the 2018 census (CNPV 2018) and updated with information from after the pandemic. The departmental shares further down come from DANE's Encuesta Nacional de Calidad de Vida 2024, published in Bogotá on 21 August 2025; the national estimate in that bulletin carries DANE's own confidence interval, and we quote it. The surname law is quoted from the text of Ley 2129 de 2021 on Función Pública's Gestor Normativo, and the two rulings from the Constitutional Court's own site. Nothing in the DANE sources covers eye colour, hair colour or blood type, so those three tables are estimates rather than official statistics — see Data Sources. Last checked: September 2026.
