Origin
The surname Martinec originated in the Czech Republic during the 13th century. It is derived from the personal name Martinek, which is a diminutive form of the name Martin. The name Martin itself can be traced back to the Roman name Martinus, which was derived from the name of the Roman god Mars.
The earliest recorded instances of the surname Martinec can be found in medieval Czech records and manuscripts. One notable example is the mention of a Jakub Martinec in a land registry document from the town of Kutná Hora, dated 1387.
During the 15th century, the surname Martinec began to spread beyond the Czech lands as people migrated to other parts of Europe. In 1492, a certain Hans Martinec was recorded as a resident of the city of Nuremberg in Germany.
One of the earliest known bearers of the surname Martinec was Jan Martinec, a Czech Protestant reformer who lived from 1490 to 1564. He was a prominent figure in the Hussite movement and played a role in the spread of Protestant ideas in Bohemia.
Another notable individual with the surname Martinec was Václav Martinec, a Czech painter and engraver who lived from 1589 to 1667. He is known for his religious paintings and engravings, many of which can be found in churches and museums across the Czech Republic.
In the 18th century, the surname Martinec also appeared in records from the Austro-Hungarian Empire. For example, a Franz Martinec was born in 1732 in the town of Brno, which was then part of the Habsburg Monarchy.
During the 19th century, the surname Martinec began to appear in records from other parts of Europe, particularly in areas with significant Czech or Slovak populations. One notable example is the Czech-American writer and journalist Jan Martinec, who was born in 1863 and immigrated to the United States in the late 19th century.
Another individual of note was the Czech writer and playwright Karel Martinec, who lived from 1892 to 1964. He is best known for his plays and novels that explored themes of Czech identity and culture.
Demographics
Among Census respondents with the surname Martinec, the largest self-reported group is White at 71.8%. The next largest groups are Hispanic (25.7%) and Two or More Races (1.7%).
The bar chart below shows how Martinec 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 Martinec 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.
