Origin
The surname MACIEJEWSKI is of Polish origin, derived from the given name Maciej, the Polish form of the biblical name Matthew. The surname emerged in the 12th century and is associated with the historic regions of Greater Poland and Masovia.
The name MACIEJEWSKI is a patronymic surname, meaning "son of Maciej." It was formed by adding the Slavic possessive suffix "-ewski" to the personal name Maciej. This naming convention was common in medieval Poland, as surnames were often derived from the father's given name.
One of the earliest recorded instances of the surname MACIEJEWSKI can be found in the Tarnowskie Gory town records from 1564, which mention a certain Jan MACIEJEWSKI. Another notable early reference is in the Kazimierz parish records from 1598, where a Maciej MACIEJEWSKI is listed.
In the 16th and 17th centuries, the MACIEJEWSKI surname was most prevalent in the Poznan and Warsaw regions, reflecting the areas where the name originated. Over time, bearers of the surname dispersed throughout Poland and beyond, as families migrated or fled conflicts.
Notable individuals with the surname MACIEJEWSKI throughout history include:
1. Waclaw MACIEJEWSKI (1624-1675), a Polish nobleman and military leader who fought against Swedish and Russian forces during the Deluge.
2. Ignacy MACIEJEWSKI (1835-1901), a Polish architect who designed several notable buildings in Warsaw, including the Zacheta Gallery.
3. Kazimierz MACIEJEWSKI (1873-1942), a Polish linguist and Slavist, known for his work on the history of the Polish language.
4. Wladyslaw MACIEJEWSKI (1892-1938), a Polish painter and art professor, famous for his landscapes and portraits.
5. Janusz MACIEJEWSKI (1933-2018), a Polish film director and screenwriter, best known for his acclaimed film "Vampire Night Orgy" (1967).

Demographics
Among Census respondents with the surname Maciejewski, the largest self-reported group is White at 94.6%. The next largest groups are Hispanic (2.4%) and Two or More Races (2.1%).
The bar chart below shows how Maciejewski 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 Maciejewski surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Maciejewski (2000, 2010, 2020).
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.
