Origin
The surname SIGGIA originated in Italy during the medieval period. It is believed to have derived from the Old Italian word "siggia," which referred to a type of coarse woolen fabric commonly produced in certain regions of the country.
One of the earliest recorded instances of the name SIGGIA can be found in a document from the city of Siena, dated 1327. This document mentions a family with the surname, suggesting that they may have been involved in the textile trade or production of the fabric from which the name originated.
In the 14th century, a notable figure bearing the name SIGGIA was Guido Siggia, a prominent merchant and politician from the city of Florence. Records indicate that he served as a member of the Signoria, the governing council of the Florentine Republic, in the years 1358 and 1368.
Another historical figure with the surname SIGGIA was Tommaso Siggia, a renowned painter from the city of Siena who lived during the 15th century. His works can still be found adorning the walls of several churches and public buildings in Siena and its surrounding areas.
During the Renaissance period, the SIGGIA family established itself as a prominent lineage in the Marche region of central Italy. In the 16th century, Giulio Siggia (1501-1572) gained recognition as a skilled architect and engineer, contributing to the design and construction of several notable buildings and fortifications in the area.
In more recent times, the surname SIGGIA has been associated with the Italian-American community. One notable individual was Pasquale Siggia (1888-1964), an Italian immigrant who settled in New York City and became a successful businessman and philanthropist, contributing to various charitable causes within the Italian-American community.
While the surname SIGGIA may have originated from a humble fabric-related trade, it has since been carried by individuals who have made their mark in various fields, from art and architecture to business and politics, spanning several centuries of Italian history.
Demographics
Among Census respondents with the surname Siggia, the largest self-reported group is White at 90.8%. The next largest groups are Hispanic (5.0%) and Asian/Pacific Islander (1.7%).
The bar chart below shows how Siggia 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 Siggia surname at the time of the 2020 Census, not any inherent property of the name itself.

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. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
