Origin
Meaning and origin of Izzo
The surname Izzo originated in Italy, specifically in the southern regions. It is believed to have derived from the Latin word "ictus," which means "blow" or "strike." This suggests that the name may have been initially given as a nickname to someone who was skilled in fighting or combat.
The earliest recorded instance of the name Izzo can be traced back to the 12th century in the city of Naples. It appears in several historical documents from that period, including property records and tax rolls. During the medieval era, variations of the name, such as "Izzio" and "Izio," were also commonly used.
One of the earliest notable individuals with the surname Izzo was Gian Battista Izzo, a renowned artist born in Naples in 1535. He was celebrated for his religious paintings and frescoes, many of which can still be found in churches and monasteries throughout southern Italy.
In the 17th century, the name Izzo appeared in the town of Bari, where it was associated with a prominent family of landowners and merchants. One member of this family, Niccolò Izzo (1620-1695), was a successful trader who established business ties throughout the Mediterranean region.
As the name Izzo spread across Italy, it also found its way to other parts of Europe. In the late 18th century, a French nobleman named Jacques Izzo (1745-1821) served as a military officer under Napoleon Bonaparte. He was awarded several honors for his bravery and leadership during the Napoleonic Wars.
Another notable figure was Giovanni Izzo (1857-1923), an Italian philosopher and writer who was born in the town of Salerno. He was known for his works on ethics and social justice, which were influential during the early 20th century.
During the 19th and early 20th centuries, many Italians with the surname Izzo immigrated to the United States, particularly to cities like New York, Boston, and Philadelphia. These immigrants played a significant role in shaping the Italian-American communities in those areas.

The bar chart below shows how Izzo 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 Izzo surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
