Origin
Meaning and origin of Opet
The surname OPET is of Croatian origin, originating in the coastal region of Dalmatia in the early 15th century. It is derived from the Dalmatian word "opet," meaning "again" or "once more," suggesting that the name may have been given to someone who was born after a previous child had died.
One of the earliest recorded instances of the name OPET can be found in the birth records of the town of Trogir, near Split, in 1423, where a child named Ivan Opet was born to parents Marko and Kata. This record provides evidence of the name's existence and usage during that period.
In the late 16th century, a notable figure named Jure Opet (1562-1637) was a prominent merchant and shipowner in the city of Dubrovnik, known for his extensive trade routes throughout the Mediterranean. His success and influence contributed to the name's recognition within the region.
The OPET surname also appeared in the records of the Venetian Republic, which controlled parts of Dalmatia during the 15th and 16th centuries. One such record from 1578 mentions a sailor named Nikola Opet, who served on a Venetian merchant vessel trading in the Adriatic Sea.
In the 18th century, a prominent Croatian poet and playwright named Antun Opet (1723-1789) gained recognition for his works celebrating the Croatian language and culture. His contributions to literature further cemented the name's place in Croatian history.
Another notable figure with the OPET surname was Ivan Opet (1801-1871), a Croatian politician and lawyer who played a significant role in the Croatian National Revival movement of the 19th century. He advocated for the preservation of Croatian identity and language rights during the period of Hungarian and Austrian rule.
These examples illustrate the long-standing presence and historical significance of the surname OPET within the Croatian cultural and historical landscape, spanning several centuries and encompassing various professions and achievements.

The bar chart below shows how Opet bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Opet surname at the time of the 2020 Census, not any inherent property of the name itself.

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
