The name was initially concentrated in the regions of Bavaria and Saxony, where it was commonly found in historical records and documents. Some of the earliest known references to the name can be traced back to the town of Achen, located in the present-day state of Baden-Württemberg.
In the 17th century, the name appeared in various German manuscripts and records, including the Kirchenbücher (church books) of several parishes in Bavaria. One notable example is the birth record of Johann Achatz, born in 1632 in the town of Aschaffenburg, located in present-day Bavaria.
Throughout the 18th and 19th centuries, the name spread across various parts of Germany, with individuals bearing the surname Achatz appearing in various historical documents and records. One prominent figure from this period was Johann Caspar Achatz (1732-1807), a German composer and organist known for his contributions to the development of church music.
In the 20th century, the name gained recognition globally due to the success of Grant Achatz, an American chef and restaurateur known for his innovative culinary techniques. Born in 1974 in Macomb County, Michigan, Achatz has earned numerous accolades, including being named one of the world's most influential chefs by Time magazine in 2008.

Demographics
Among Census respondents with the surname Achatz, the largest self-reported group is White at 96.3%. The next largest groups are Hispanic (1.6%) and Two or More Races (1.1%).
The bar chart below shows how Achatz 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 Achatz 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.
