Origin
The surname Kline originated in Germany and is a variation of the German word "klein," which means "small." This surname was likely first used to refer to a person of small stature or someone who was considered small or insignificant in their community.
The name can be traced back to the Middle Ages, with some of the earliest recorded instances appearing in German parish records and historical documents from the 13th and 14th centuries. Variations of the spelling, such as Klyne and Clyne, were also common during this time period.
In the 16th century, the name Kline began to appear in various regions of Germany, including Bavaria, Saxony, and the Rhineland. During this time, the name was often associated with specific professions, such as tailors or cobblers, who were known for their attention to detail and precision in their work.
One of the earliest notable individuals with the surname Kline was Johann Kline, a German merchant and landowner who lived in the city of Nuremberg in the late 15th century. Records indicate that he was a prominent figure in the local community and owned several properties in the city.
Another notable figure with the Kline surname was Philipp Kline, a German Lutheran theologian and educator who lived in the 17th century. He was a professor at the University of Heidelberg and published several works on theology and philosophy.
In the 18th century, the name Kline began to spread beyond Germany as families with this surname immigrated to other parts of Europe and even to the American colonies. One notable individual from this period was Johann Adam Kline, a German-born farmer who settled in Pennsylvania in the mid-1700s and established a successful agricultural operation.
In the 19th century, the Kline surname continued to gain prominence, particularly in the United States. One notable figure was John Kline, an American minister and abolitionist who was born in 1797 in Virginia. He was a vocal opponent of slavery and played a significant role in the Underground Railroad, helping to guide escaped slaves to freedom.
Another notable individual with the Kline surname was Harriet Kline, an American suffragist and women's rights activist who was born in 1846 in New York. She was a prominent figure in the women's suffrage movement and worked tirelessly to secure the right to vote for women in the United States.
Over the centuries, the Kline surname has been associated with various occupations, from merchants and farmers to theologians and activists. While its origins can be traced back to Germany and the Middle Ages, the name has since spread across the globe, reflecting the diverse histories and experiences of those who bear it.
Demographics
Among Census respondents with the surname Kline, the largest self-reported group is White at 91.2%. The next largest groups are Two or More Races (3.1%) and Hispanic (2.8%).
The bar chart below shows how Kline 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 Kline 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.
