Origin
The surname CHIOCCHI is of Italian origin, specifically from the Abruzzo region of central Italy. It is believed to have derived from the Italian word "chioccia," meaning "brooding hen." This suggests that the name may have originated as a nickname or descriptive name for someone who exhibited characteristics associated with a brooding hen, such as being nurturing, protective, or constantly surrounded by many people or children.
The earliest known record of the CHIOCCHI surname dates back to the 16th century in the town of Castiglione Messer Raimondo, located in the province of Teramo, Abruzzo. A document from 1587 mentions a certain Pietro CHIOCCHI, a landowner and farmer in the area. This indicates that the name was already well-established in the region by that time.
In the 17th century, the name appears in the records of the nearby town of Roseto degli Abruzzi. A prominent figure was Nicola CHIOCCHI, born in 1642, who was a respected local merchant and member of the town council. His son, Antonio CHIOCCHI (1679-1745), followed in his footsteps and became a successful businessman and landowner.
As the CHIOCCHI family grew and dispersed throughout the region, variations in spelling emerged, such as CHIOCCI, CHIOCCIA, and CHIOCCA. These variations were likely due to regional dialects and differences in pronunciation or scribal errors in record-keeping.
One notable individual with the surname CHIOCCHI was Gaspare CHIOCCHI (1812-1891), a renowned artist and sculptor from the town of Teramo. He was renowned for his intricate wood carvings and religious sculptures, which adorned several churches in the region. His works are considered part of the cultural heritage of Abruzzo.
Another prominent figure was Giuseppe CHIOCCHI (1878-1945), a politician and lawyer from Roseto degli Abruzzi. He served as a member of the Italian Parliament and was actively involved in local politics, advocating for the rights and interests of the people of Abruzzo.
While the CHIOCCHI surname is not among the most common in Italy, it has a rich history deeply rooted in the Abruzzo region, where it originated and flourished for centuries. The name has been carried by farmers, merchants, artists, and political figures, all contributing to the cultural tapestry of the area.
Demographics
Among Census respondents with the surname Chiocchi, the largest self-reported group is White at 95.0%. The next largest groups are Hispanic (4.2%) and Asian/Pacific Islander (0.8%).
The bar chart below shows how Chiocchi 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 Chiocchi 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.
