Origin
The surname Ungar is of Hungarian origin, derived from the word "ungar," which means "Hungarian" in several languages, including Swedish, Danish, and Norwegian. This name likely originated in the Middle Ages when Hungary was known as the Kingdom of Hungary.
The earliest recorded use of the name Ungar dates back to the 12th century, when it appeared in various Hungarian documents and records. It was often used to identify individuals who had migrated from Hungary or had Hungarian ancestry.
In the 13th century, the name Ungar was mentioned in the "Registrum Ecclesiae Parochialis de Magyar," a medieval manuscript that documented parish records in Hungary. This suggests that the name was well-established in the region during this period.
One of the earliest notable individuals with the surname Ungar was Pal Ungar, a Hungarian nobleman and military commander who lived in the 15th century. He played a significant role in defending Hungary against Ottoman invasions.
In the 16th century, the name Ungar appeared in various German records, indicating that individuals with this surname had migrated to German-speaking regions. This was likely due to the political and religious turmoil that plagued Hungary during this time.
During the 17th and 18th centuries, the name Ungar became more widespread across Europe as Hungarian immigrants settled in various countries. One notable figure from this period was Janos Ungar, a Hungarian theologian and philosopher who lived from 1670 to 1744.
In the 19th century, the Ungar surname gained prominence in the United States, as many Hungarian immigrants sought new opportunities in the New World. One of the most famous individuals with this name was Max Ungar, a Hungarian-American businessman and philanthropist who lived from 1837 to 1917.
Another notable figure was Estelle Ungar, an American professional poker player who was born in 1936 and won several prestigious tournaments, including the World Series of Poker Main Event in 1997.

Demographics
Among Census respondents with the surname Ungar, the largest self-reported group is White at 95.7%. The next largest groups are Hispanic (2.5%) and Two or More Races (1.0%).
The bar chart below shows how Ungar 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 Ungar 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.
