Origin
The surname Bitsoi has its origins in the Navajo language and culture of the southwestern United States. It is believed to have emerged in the late 18th or early 19th century among the Navajo people, who are an Indigenous nation with roots in the Four Corners region where Arizona, New Mexico, Utah, and Colorado meet.
The name Bitsoi is thought to be derived from the Navajo word "bits'iis," which means "flat" or "broad." This may have been a descriptive name referring to a physical characteristic or a reference to a specific geographic location associated with the family.
While written records of Navajo surnames are relatively scarce from the early periods, the name Bitsoi is known to have appeared in various documents and records kept by the United States government and tribal authorities in the 19th and 20th centuries.
One of the earliest known individuals with the surname Bitsoi was Hosteen Bitsoi, a Navajo leader and medicine man who lived in the mid-19th century. He was renowned for his knowledge of traditional Navajo healing practices and played a significant role in preserving and transmitting Navajo culture and traditions.
Another notable figure was Bitsui Bitsui, a Navajo silversmith and artist who was born in 1872 and is recognized for his contributions to the development of Navajo silversmithing and jewelry-making.
In the 20th century, Carl Bitsoi (1924-2013) was a prominent Navajo artist and educator who taught at the Institute of American Indian Arts and helped to promote and preserve Navajo art and culture.
Wilma P. Bitsoi (1927-2005) was a Navajo linguist and educator who worked tirelessly to document and preserve the Navajo language. She contributed significantly to the development of Navajo language curricula and resources.
Lastly, Shonto Begay Bitsoi (1936-2015) was a highly respected Navajo Code Talker who served in the United States Marine Corps during World War II, using the Navajo language to transmit coded messages that were crucial to the Allied forces' success.
Demographics
Among Census respondents with the surname Bitsoi, the largest self-reported group is American Indian/Alaska Native at 84.0%. The next largest groups are White (9.2%) and Two or More Races (5.9%).
The bar chart below shows how Bitsoi 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 Bitsoi 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.
