Origin
Meaning and history of Estibaliz
The name Estibaliz originates from the Basque language spoken in the regions of northern Spain and southwestern France. It is derived from the Basque words "itze" meaning "word" and "bail" meaning "value" or "worth," combined to form the name which means "of great value" or "precious word."

In the 12th century, a Basque noblewoman named Estibaliz de Lizarra was mentioned in historical records as the wife of Sancho VI, King of Navarre. This is one of the earliest documented cases of the name being used.
Another notable historical figure with the name Estibaliz was Estibaliz de Carranza, a 15th-century Basque noblewoman who served as a lady-in-waiting to Queen Isabella I of Castile.

FAQ
Estibaliz: questions and answers
How many people in the U.S. are named Estibaliz?
Name Census puts the figure at roughly 22 living Americans. We arrive at this by taking every SSA birth registration for Estibaliz going back to 1880 and adjusting each cohort for expected survival using CDC actuarial life tables. The result is an age-weighted living-bearer count, not a raw birth total. That works out to about 1 in 15,579,743 US residents.
Is Estibaliz a common name?
We classify Estibaliz as "Very Rare". It ranks above 41.6% of all first names in the SSA dataset by living bearers. Across the full history of the data, 23 babies have been registered with this name.
When was Estibaliz most popular?
The single biggest year for Estibaliz was 1978, when 6 babies received the name. The fact that the average living Estibaliz is about 17 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
What does the SSA popularity chart show?
The chart tracks births, not the number of people alive with the name today. Each point shows how many babies were given the name Estibaliz in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Estibaliz a female name?
Yes, 100.0% of people registered as Estibaliz in the SSA data are female. You can see the full per-sex comparison in the gender distribution section above, which includes the latest year rank, birth count, and peak year for each sex.
Is Estibaliz still being used today?
Yes. The SSA still recorded Estibaliz in 2024, and the page above shows its latest-year rank where available. A name can be well past its peak and still remain in steady use, especially if it built up a large population over earlier decades.
Why can a name have a lot of living bearers even if it is not trendy now?
Because living-bearer counts and current baby-name popularity measure different things. A name like Estibaliz can build up a very large population over many decades, even if fewer parents are choosing it now than they did at its peak.
Where does this data come from?
First-name figures come from the Social Security Administration's national baby name files, which cover every name on a birth certificate from 1880 to 2024. Living-bearer estimates layer in CDC actuarial life tables broken out by sex to account for mortality. The population baseline (342,754,338) is the Census Bureau's latest national estimate. You can read the full calculation on our methodology page.
Does every first name have Census demographic data?
No. The public Census first-name release only covers names that met the Bureau's publication rules, so many rarer names in the SSA files do not have a published Census demographic snapshot. In those cases, the page still shows the SSA trend, gender history, and state data.
