๐ How Rare Are You in Philippines?
๐ต๐ญ Genetic Landscape of Philippines
The Philippines has been a genetic crossroads of Southeast Asia for millennia. The Aeta (Negrito) people are among the earliest inhabitants with Australo-Melanesian ancestry. Centuries of Malay migration, 333 years of Spanish colonization, American influence, Chinese trade, and Japanese presence have created a uniquely layered genetic profile. Filipino DNA studies show one of the most complex admixture patterns in Southeast Asia, with significant variation across the 7,641 islands.
Surnames here mislead almost everyone who reads them. In 1849 the Spanish governor-general Narciso Claveria ordered families to take fixed surnames from a printed catalogue distributed town by town, mainly to make tax and civil records workable. Officials handed the list out alphabetically, so whole municipalities still cluster around a single letter, and a map of Filipino surnames is partly a map of which pages each town received. A Spanish-looking name therefore says very little about Spanish ancestry. Older names survived where Spanish administration reached least, above all in the Muslim south, while Chinese trading households often fused an ancestor's full name into one word, which is why surnames like Cojuangco and Yuchengco look unlike anything else in the archipelago.
๐ชช What the national ID writes down about you
Republic Act No. 11055, the Philippine Identification System Act, was approved on 6 August 2018. Section 8(a) lists exactly ten pieces of demographic data the PhilSys registry holds about a person: full name, sex, date of birth, place of birth, blood type, address, Filipino or resident alien status, and — optional — marital status, mobile number and e-mail address. Blood type is item five. Section 8(b) lists the biometrics: a front facing photograph, a full set of fingerprints, an iris scan and, if necessary, other identifiable features as determined in the implementing rules.
That statute explains the tiles at the top of this page better than any dataset does. A blood group is something the Philippine state writes down for every registrant. Eye colour and hair colour are not: neither appears among the ten demographic items, and the three biometrics the Act names are identifiers rather than a colour recorded about you. We found no published national tally of PhilSys blood types, so the blood figures below still come from elsewhere.

🧮 Calculate Your Rarity in Philippines
Pick your eye colour, hair colour and blood type. The calculator uses Philippines'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 →
โ๏ธ The Civil Code’s rule for two people with the same name
Republic Act No. 386, the Civil Code of the Philippines, approved on 18 June 1949, contains Title XIII, headed “Use of Surnames”, Articles 364 to 380. Article 374 reads in full: “In case of identity of names and surnames, the younger person shall be obliged to use such additional name or surname as will avoid confusion.” That is a duty to be distinguishable, written into a civil code — what a name rarity check measures, turned into an obligation.
Article 375 handles the same collision inside a family. Where an ascendant and a descendant share a name, “Junior” can be used only by a son; grandsons and other direct male descendants must either add a middle name or the mother’s surname, or add the Roman numerals II, III, and so on. Article 376: no person can change a name or surname without judicial authority. Article 380: apart from pen and stage names, no one shall use different names and surnames.
๐ฐ Changing a first name takes two weeks of newspaper notices
Article 376 meant a court, or nothing. Republic Act No. 9048, approved on 22 March 2001, amended it: a city or municipal civil registrar can change a first name or nickname without a judge. Section 4 lists the grounds — the petitioner finds the name “ridiculous, tainted with dishonor or extremely difficult to write or pronounce”; the new name has been “habitually and continuously used” and the petitioner is publicly known by it; or “the change will avoid confusion”, Article 374’s phrase again.
None of it is private. Section 5 requires the petition to be published “at least once a week for two (2) consecutive weeks in a newspaper of general circulation”. Republic Act No. 10172, approved on 15 August 2012, extended the same over-the-counter route to the day and month in a date of birth, and to the sex entry, where the error is clerical or typographical. So the day and month of a Philippine birth date can be corrected without a judge; the year is not on that list, so it still takes one.
โญ Rare Facts About Philippines
Where the figures on this page come from
The Philippine Statistics Authority (RA 10625, 2013) publishes the census, and the DOST’s Food and Nutrition Research Institute measures adults in the National Nutrition Survey. The population and height tiles are rounded estimates, not figures quoted from a named release. Blood services run under RA 7719, the National Blood Services Act of 1994, which has the Department of Health plan and implement the National Voluntary Blood Services Program together with the Philippine National Red Cross and the Philippine Blood Coordinating Council; blood is typed at licensed blood banks, so any published share reflects donors, not a random sample. The national ID system does not record eye or hair colour — neither appears in the data RA 11055 lets PhilSys collect — and we found no Philippine agency publishing figures for either, so those percentages have no official source.
