Origin
The surname "DEKAT" is believed to have originated from Germany, with its earliest recorded use dating back to the 16th century. It is thought to have derived from the German word "dekat," which referred to a type of fabric or cloth, suggesting that the name may have been associated with individuals involved in the textile trade or industry.
During the late medieval period, surnames in German-speaking regions often originated from occupations, physical characteristics, or places of residence. The name "DEKAT" could have been an occupational surname, indicating an individual's profession or trade related to the production or sale of a particular fabric.
One of the earliest recorded instances of the surname "DEKAT" can be found in the parish records of the town of Göttingen, Lower Saxony, Germany. In the year 1587, a certain Hans DEKAT was mentioned as a resident of the town, and his name appeared in various legal documents and transactions.
As German families migrated across Europe and beyond, the surname "DEKAT" spread to other regions. In the 17th century, records show a family named DEKAT residing in the city of Amsterdam, Netherlands, where they were involved in the lucrative textile trade. Notable individuals from this family include Pieter DEKAT (1621-1687), a successful merchant, and his son, Jan DEKAT (1657-1724), who served as a prominent alderman in the city.
Moving forward to the 18th century, the name "DEKAT" can be found in historical records from various parts of Germany, including Prussia and the Rhineland. One noteworthy figure was Friedrich DEKAT (1738-1812), a respected scholar and author who published several works on philosophy and theology.
In the 19th century, the surname "DEKAT" gained recognition in the field of literature. Karl DEKAT (1819-1892) was a German novelist and poet whose works explored themes of romance and nature. His contemporaries included Theodor DEKAT (1825-1901), a renowned playwright and dramatist whose plays were performed in theaters across Germany.
As immigrant communities established themselves in different parts of the world, the surname "DEKAT" traveled beyond its German origins. In the early 20th century, records indicate the presence of individuals with this surname in countries such as the United States, Canada, and Australia, likely descendants of earlier German immigrants seeking new opportunities.
Demographics
Among Census respondents with the surname Dekat, the largest self-reported group is White at 90.4%. The next largest groups are Two or More Races (4.3%) and Hispanic (3.5%).
The bar chart below shows how Dekat 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 Dekat surname at the time of the 2020 Census, not any inherent property of the name itself.
