Origin
Meaning and history of Gustauo
The name Gustauo has its origins in the Old Norse language, where it was derived from the word "gūst-hafr," meaning "battle-goat." This likely referred to a fierce warrior or leader who was as courageous as a goat defending its herd. The name first appeared in written records around the 9th century AD, during the height of the Viking Age.
As the Vikings traveled and settled across Europe, the name spread to different regions and underwent various spelling changes. In Old Swedish, it became "Göstaf," while in Old German, it was rendered as "Gustab" or "Gustave." These early variations eventually evolved into the modern form, "Gustauo."
One of the earliest documented examples of the name can be found in the 12th-century Icelandic saga "Heimskringla," which mentions a Norwegian king named Gustauo Eriksson, who ruled from 1238 to 1250. Another notable historical figure was Gustauo Vasa, a Swedish nobleman who led a rebellion against Danish rule and became King of Sweden in 1523.
In the 16th century, the name gained prominence with Gustauo Adolfo, also known as Gustavus Adolphus, the King of Sweden from 1611 to 1632. He played a significant role in the Thirty Years' War and is considered one of the greatest military leaders in Swedish history.
Other famous individuals named Gustauo include Gustauo Klimt, the renowned Austrian painter and one of the most prominent members of the Vienna Secession movement (1862-1918), and Gustauo Mahler, the influential Austrian composer and conductor of the late Romantic period (1860-1911).
During the 19th century, the name was also popularized by Gustauo Courbet, a French painter known for his influential works in the Realist tradition (1819-1877), and Gustauo Flaubert, the celebrated French novelist who wrote the classic novel "Madame Bovary" (1821-1880).

FAQ
Gustauo: questions and answers
How many people in the U.S. are named Gustauo?
Name Census puts the figure at roughly 5 living Americans. We arrive at this by taking every SSA birth registration for Gustauo 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 68,550,868 US residents.
Is Gustauo a common name?
We classify Gustauo as "Very Rare". It ranks above 18.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 5 babies have been registered with this name.
When was Gustauo most popular?
The single biggest year for Gustauo was 1987, when 5 babies received the name. The fact that the average living Gustauo is about 38 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 Gustauo in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Gustauo a male name?
Yes, 100.0% of people registered as Gustauo in the SSA data are male. 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 Gustauo still being used today?
Yes. The SSA still recorded Gustauo 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 Gustauo 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.
