Origin
The surname LEINFELDER is of German origin, originating in the German-speaking regions of Central Europe during the medieval period. The name is believed to be derived from the Middle High German words "lin" meaning "flax" and "felder" meaning "fields," suggesting a connection to the cultivation of flax or occupation as a linen weaver.
One of the earliest recorded instances of the LEINFELDER surname dates back to the 14th century in the region of Saxony, where it appeared in various spellings such as Leynfelder, Leinfelder, and Leinfelter. This variation in spelling was common during that era due to the lack of standardized orthography.
The LEINFELDER name can be traced back to several notable individuals throughout history. In the 16th century, Hans LEINFELDER (1520-1588) was a prominent linen merchant and guild member in the city of Leipzig. His son, Johann LEINFELDER (1562-1631), followed in his footsteps and became a respected linen trader.
In the 18th century, the LEINFELDER surname gained prominence with the birth of Johann Gottfried LEINFELDER (1715-1788), a renowned German theologian and philosopher. His literary works and teachings significantly influenced the intellectual landscape of his time.
Another notable figure was Friedrich Wilhelm LEINFELDER (1801-1876), a German architect and urban planner. He was responsible for designing several iconic buildings and contributing to the development of various cities in the region.
During the 19th century, the LEINFELDER family produced several accomplished individuals, including Karl LEINFELDER (1832-1911), a renowned botanist and horticulturist who made significant contributions to the study of plant species.
It is worth noting that the LEINFELDER surname has been associated with various place names in Germany, such as Leinfeld, Leinfeldern, and Leinfelden, which further reinforces the connection between the name and the cultivation of flax.
Demographics
Among Census respondents with the surname Leinfelder, the largest self-reported group is White at 95.9%. The next largest groups are Asian/Pacific Islander (1.7%) and Hispanic (0.8%).
The bar chart below shows how Leinfelder 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 Leinfelder 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 Leinfelder (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.
