Origin
The surname LUCIW originated in Ukraine, tracing its roots back to the 16th century. It is a variant of the Ukrainian surname Lutsiv, which was derived from the toponym Lutsk, referring to the historic city of Lutsk in northwestern Ukraine.
LUCIW is a phonetic transcription of the Ukrainian surname Луцiв (Lutsiv), which was commonly encountered in various historical records and manuscripts from the region around Lutsk. The earliest known mention of this surname dates back to a land registry from 1587, where a certain Ivan Lutsiv was listed as a landowner in the Volhynian region.
In the 17th century, the surname LUCIW began appearing in church records and official documents across Volhynia and Galicia, two regions with strong Ukrainian cultural and linguistic influences. Notable bearers of this surname during this period include Hryhoriy Luciw (1603-1679), a prominent Orthodox priest and theologian from the town of Zolochiv.
As the Ukrainian diaspora spread throughout Europe and beyond in the late 19th and early 20th centuries, the surname LUCIW became more widely dispersed. One of the earliest known immigrants bearing this name was Petro Luciw (1872-1943), who settled in Canada in the 1890s and became a prominent figure in the Ukrainian-Canadian community.
Other notable individuals with the surname LUCIW include:
1. Yuriy Luciw (1892-1961), a Ukrainian poet and writer from Galicia.
2. Oleksandr Luciw (1917-1991), a Ukrainian-American artist and painter known for his vibrant depictions of Ukrainian folklore.
3. Mykola Luciw (1923-2002), a Ukrainian-Canadian historian and author who wrote extensively on the history of Ukraine and its diaspora.
4. Mariya Luciw (1925-2008), a Ukrainian-Canadian opera singer and vocal teacher.
5. Bohdan Luciw (born 1944), a Ukrainian-American mathematician and computer scientist who made significant contributions to the field of cryptography.
Demographics
Among Census respondents with the surname Luciw, the largest self-reported group is White at 89.8%. The next largest groups are Hispanic (5.1%) and Two or More Races (3.4%).
The bar chart below shows how Luciw 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 Luciw 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.
