One of the earliest recorded instances of the surname Opfermann can be found in the town of Hildesheim, Lower Saxony, Germany, in the late 1500s. The name was also present in the nearby regions of Hanover and Brunswick during this time period.

During the 18th century, the surname Opfermann spread to other parts of Germany, with records indicating families with this name residing in cities such as Berlin and Hamburg. One prominent individual was Friedrich Opfermann, a merchant and ship owner from Hamburg, who lived from 1732 to 1798.
As the 19th century progressed, the surname Opfermann continued to be found across Germany, with some families migrating to other parts of Europe and beyond. One notable bearer of this name was Karl Opfermann, a German mathematician and astronomer who lived from 1819 to 1876.

Demographics
Among Census respondents with the surname Opfermann, the largest self-reported group is White at 84.3%. The next largest groups are Hispanic (9.6%) and Two or More Races (4.3%).
The bar chart below shows how Opfermann 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 Opfermann 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.
