Origin
Meaning and origin of Jasmund
The surname Jasmund originated in Germany, appearing as early as the 13th century. It is derived from the Old High German words "gias" meaning "bend" and "munt" meaning "mouth" or "estuary." This suggests the name likely referred to someone living near a bend in a river mouth or estuary.
The earliest recorded spelling variations include Jasmund, Jasemunde, and Jasemunt. These early spellings point to the name's origins on the Baltic Sea island of Rügen, particularly near the Jasmund National Park area. This region is known for its striking chalk cliffs and beech forests along the Jasmund peninsula.
In medieval records from the 13th to 15th centuries, there are entries for individuals with the name Jasmund living in towns like Bergen auf Rügen and Putbus on the island of Rügen. A notable early bearer was Hans Jasmund, a merchant active in the Hanseatic League port city of Stralsund in the late 1400s.
The Jasmund name spread beyond Rügen over the following centuries. In 1597, Matthias Jasmund was recorded as a landowner in Demmin, a town in what is now Mecklenburg-Vorpommern. Another early bearer was Johann Jasmund, born around 1620 in Greifswald, who became a respected Lutheran theologian and rector.
Moving into the 1700s, examples include Andreas Jasmund (1718-1784), a pastor in Mellen, Prussia, and his son Johann Jasmund (1756-1828), who attained the rank of major in the Prussian army during the Napoleonic Wars. In the 1800s, Carl Jasmund (1826-1892) was a noted German painter from Greifswald.
While primarily a northern German surname, Jasmund has also appeared in various records across central Europe over the centuries. A few other notable bearers were the Bohemian artist Josef Jasmund (1828-1901), the Prussian architect Bernhard Jasmund (1836-1911), and the German World War I general Max Jasmund (1869-1943).

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

Does the Census include every surname?

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.
