Origin
The surname Nemec is of German origin, derived from the German word "Nemet" which means "mute" or "unable to speak." It is believed to have emerged in the 14th century as a descriptive surname, likely referring to someone who was mute or had a speech impediment.
Variants of the name include Nemetz, Nemecek, and Nemecky. These variations can be found in regions of Germany, Austria, and the Czech Republic, where the name has a strong presence.
One of the earliest recorded instances of the name Nemec can be found in the Liber Vetustissimus Gorlicensis, a 15th-century manuscript from the town of Görlitz, in modern-day Germany. The entry mentions a certain "Peter Nemec" who was a resident of the town in the year 1419.
In the 16th century, the name appears in various records from the region of Bohemia, which was then part of the Holy Roman Empire. One notable figure was Jan Nemec (1523-1589), a Catholic priest and writer who authored several religious works.
The 17th century saw the emergence of the Nemec family in the town of Kutná Hora, located in the present-day Czech Republic. Records from this period mention a merchant named Matouš Nemec (1612-1679), who was a prominent figure in the local trade guild.
Moving into the 18th century, the name Nemec gained recognition in the field of music with the birth of Johann Nepomuk Nemec (1738-1804), a Czech composer and violinist who served as the Kapellmeister (music director) at the court of Prince Esterházy in Hungary.
In more recent times, the 20th century saw the rise of notable individuals bearing the surname Nemec, such as Jan Nemec (1936-2016), a renowned Czech film director known for his works like "Diamonds of the Night" and "The Party and the Guests."
Other notable figures with the surname Nemec include the Czech painter and illustrator Jaroslav Nemec (1935-2018), the American baseball player Mark Nemec (born 1967), and the Canadian actress Ona Grauer (née Nemec, born 1975).
Demographics
Among Census respondents with the surname Nemec, the largest self-reported group is White at 92.9%. The next largest groups are Hispanic (2.9%) and Two or More Races (2.6%).
The bar chart below shows how Nemec 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 Nemec surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Nemec (2000, 2010, 2020).
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.
