Origin
The surname Miroslaw originated in Poland, tracing its roots back to the Middle Ages. It is a compound name formed from the Slavic elements "mir" meaning peace and "slaw" meaning glory or fame, thus translating to "peaceful glory" or "glorious peace."
The name first appeared in historical records from the 13th century, found in medieval manuscripts and documents from the regions of Greater Poland and Silesia. Early variations of the spelling included Miroslau, Myroslav, and Miroslaus.
One of the earliest known bearers of the Miroslaw name was Miroslav of Cieszyn, a Polish nobleman and military commander who lived in the late 13th century. He is mentioned in chronicles from the time for his role in defending the Duchy of Opole against Bohemian invaders.
In the 14th century, the name appears in connection with the village of Miroslawice, located in the modern-day Łódź Voivodeship of central Poland. This place name likely derived from an early settler named Miroslaw, reflecting the common practice of naming settlements after their founders or landowners.
Notable historical figures with the surname Miroslaw include Jan Miroslaw (1556-1623), a Polish poet and translator during the Renaissance period, and Kazimierz Miroslaw (1832-1899), a 19th-century Polish painter and art professor.
Other prominent individuals bearing this name were Stanisław Miroslaw (1875-1941), a Polish lawyer and politician who served as a member of the Sejm (parliament) in the early 20th century, and Mirosław Hermaszewski (born 1941), a Polish Air Force pilot and the first Polish astronaut to travel into space, aboard the Soyuz 30 mission in 1978.
Throughout its history, the Miroslaw surname has maintained a strong connection to its Polish roots, reflecting the cultural and linguistic heritage of the Slavic peoples who have shaped the region over centuries.
Demographics
Among Census respondents with the surname Miroslaw, the largest self-reported group is White at 96.6%. The next largest groups are Hispanic (1.7%) and Black (0.8%).
The bar chart below shows how Miroslaw 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 Miroslaw 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.
