Origin
The surname DYKHOFF originated in Germany, first appearing in records from the 16th century. It is derived from the Low German words "dik" meaning thick or fat, and "hoff" meaning a farmstead or homestead. Thus, DYKHOFF likely referred to someone who lived on a large or prosperous farm.
Early variations of the spelling included Dikhoff, Dickhoff, and Dyckhoff. The name was particularly prevalent in the northern German states of Schleswig-Holstein and Lower Saxony. One of the earliest recorded instances is Hans Dikhoff, born around 1525 in the town of Lübeck.
In the 17th century, the DYKHOFF name appears in church records from the village of Wittmundhaven in East Frisia. A farmer named Hinrich Dyckhoff is listed as a landowner there in 1632. His descendants continued using the DYKHOFF spelling for generations.
As the name spread across German-speaking regions, it was sometimes associated with the Low German word "dyk" meaning dike or embankment, suggesting the family may have lived near flood protection structures. However, most experts believe the "dik" root refers to stoutness or prosperity.
Notable people with the surname DYKHOFF include Johann Dyckhoff (1711-1753), a Lutheran pastor in Schwelm, and August Dykhoff (1822-1890), a jurist and politician who served in the Prussian parliament. In the 20th century, Hans Dykhoff (1901-1980) was a German naval officer during World War II.
Other examples are Heinrich Dykhoff (1873-1945), a banker and businessman from Bremen, and Margarete Dykhoff (1909-1992), a German stage and film actress popular in the 1930s and 1940s. While not appearing in major historical sources like the Domesday Book, the DYKHOFF name has a rich legacy tracing back to 16th century northern Germany.
Demographics
Among Census respondents with the surname Dykhoff, the largest self-reported group is White at 96.3%. The next largest groups are Two or More Races (3.2%) and Asian/Pacific Islander (0.5%).
The bar chart below shows how Dykhoff 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 Dykhoff 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.
