Origin
The surname Erstad originates from Norway, tracing its roots back to the Middle Ages. It is believed to have derived from the Old Norse words "erð" meaning "sandy ground" and "staðr" signifying "place" or "farm." This etymology suggests that the name was initially associated with individuals who lived on or owned sandy, arable land.
Erstad is a locational surname, indicating that the earliest bearers of this name hailed from a specific place known as Erstad. Historical records show that there were several villages and farms bearing this name in various parts of Norway, particularly in the regions of Vestfold, Østfold, and Telemark.
One of the earliest recorded instances of the Erstad name dates back to the 14th century, when it appeared in the Diplomatarium Norvegicum, a collection of medieval Norwegian diplomatic documents. This suggests that the name had already established itself as a distinct surname by that time.
In the 16th century, the Erstad surname can be found in a Norwegian census record from 1593, which listed several individuals bearing this name in the town of Tønsberg, located in the county of Vestfold.
The 17th century saw the emergence of a prominent figure named Hallvard Erstad (1615-1679), a Norwegian clergyman and author who served as the rector of the Cathedral School in Trondheim. His literary works, including a Latin grammar book and a collection of sermons, contributed to the dissemination of the Erstad name within academic and religious circles.
Another notable individual with the Erstad surname was Hans Erstad (1798-1873), a Norwegian poet and playwright born in the village of Eidsvoll. His literary works, often infused with patriotic themes and a celebration of Norwegian culture, gained him recognition during the Romantic Nationalist movement of the 19th century.
In the 20th century, Rolf Erstad (1905-1986) was a Norwegian businessman and philanthropist who made significant contributions to the development of the town of Sandefjord. He established several businesses and donated generously to educational and cultural institutions, leaving a lasting impact on the local community.
The Erstad name has also been associated with various locations and place names throughout Norway. For instance, the farm Erstad Søndre in Sandefjord and the village of Erstad in Østfold both bear the name, serving as reminders of its geographical origins.
Demographics
Among Census respondents with the surname Erstad, the largest self-reported group is White at 92.7%. The next largest groups are Hispanic (4.5%) and Asian/Pacific Islander (1.3%).
The bar chart below shows how Erstad 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 Erstad 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.
