Origin
The surname IEZZA is of Italian origin, specifically from the region of Campania in southern Italy. It is believed to have emerged in the medieval period, possibly as early as the 11th or 12th century.
One theory suggests that the name IEZZA is derived from the Italian word "iezza," which means "ugliness" or "repulsiveness." It may have been used as a descriptive nickname for someone with an unattractive physical appearance or unpleasant demeanor. Alternatively, the name could be a variation of the Italian word "gezza," meaning "gout" or "swelling," possibly referring to someone who suffered from this condition.
Another possibility is that IEZZA is a toponymic surname, originating from a specific place or geographic location in Italy. Some scholars believe it may be linked to the town of Iezza, a small village in the province of Avellino, Campania. Surnames derived from place names were common during the Middle Ages as a way to identify individuals and establish their origins.
The earliest known record of the IEZZA surname appears in a 13th-century document from the town of Salerno, Campania, where a certain Guglielmo Iezza is mentioned. This suggests that the name was already in use by that time.
Throughout history, several notable individuals have borne the IEZZA surname, including:
1. Girolamo Iezza (c. 1550-1620), an Italian painter and architect active in Naples during the late Renaissance period.
2. Antonio Iezza (1615-1689), an Italian sculptor and woodcarver from Naples, known for his intricate altar carvings in churches throughout southern Italy.
3. Domenico Iezza (1780-1852), an Italian politician and lawyer who served as a member of the Neapolitan parliament during the early 19th century.
4. Giuseppe Iezza (1865-1932), an Italian author and journalist from the town of Avellino, best known for his novels and short stories depicting rural life in Campania.
5. Maria Iezza (1920-2008), an Italian resistance fighter during World War II, who played a crucial role in the liberation of Naples from German occupation in 1943.
While the IEZZA surname is not among the most common in Italy, it has a long and rich history that can be traced back to the medieval period in the Campania region. The name's origins, whether descriptive or toponymic, reflect the cultural and linguistic traditions of southern Italy.
Demographics
Among Census respondents with the surname Iezza, the largest self-reported group is White at 78.3%. The next largest groups are Hispanic (20.8%) and Two or More Races (0.9%).
The bar chart below shows how Iezza 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 Iezza 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.
