Origin
Meaning and origin of Cabais
The surname CABAIS has its origins in the Iberian Peninsula, specifically in the region of Catalonia, Spain. Its earliest roots can be traced back to the 11th century during the Christian Reconquista of the Iberian Peninsula from the Moors. The name is believed to be derived from the Catalan word "cabàs," which means "basket" or "hamper," possibly referring to an occupation or trade related to basketry or weaving.
One of the earliest recorded references to the CABAIS surname is found in the "Llibre del Repartiment," a medieval manuscript that documented the distribution of lands and properties in the newly conquered territories of Valencia after the Moor expulsion in the 13th century. Several individuals with the surname CABAIS were listed as recipients of land grants in this historic document.
In the 14th century, a notable figure bearing the CABAIS surname was Pere Cabais, a merchant and trader from Barcelona who played a significant role in the expansion of Catalan trade routes across the Mediterranean. His business ventures and travels are documented in various historical accounts from that period.
During the 15th century, the CABAIS surname gained prominence in the region of Catalonia, with several individuals holding prominent positions in local government and religious institutions. One such individual was Bernat Cabais, a respected jurist and legal scholar who served as a magistrate in the city of Girona from 1462 to 1478.
In the 16th century, the CABAIS surname spread beyond the borders of Catalonia and Spain, with some members of the family migrating to other parts of Europe and the Americas. Notably, Jaume Cabais, a navigator and explorer, accompanied the Spanish conquistador Hernán Cortés on his expedition to Mexico in 1519. Cabais played a crucial role in the establishment of the Spanish settlement in what is now Veracruz.
Another notable figure from the 16th century was Isabel Cabais, a renowned poetess and writer from Valencia. Her works, which explored themes of love, spirituality, and societal issues, were widely acclaimed and published during her lifetime (1540-1612).
As the centuries progressed, the CABAIS surname continued to spread across various regions, with descendants making significant contributions in various fields, such as arts, sciences, and politics. However, it is important to note that the prevalence and distribution of the surname may have varied over time due to historical events, migrations, and other societal factors.

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 Cabais surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Cabais (2010, 2020).
Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.

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