Origin
Meaning and origin of Kroma
The surname Kroma has its origins in the Slavic region of Central and Eastern Europe, dating back to the 9th century. It is believed to be derived from the old Slavic word "krom," which means "edge" or "border." This suggests that the name was originally given to someone who lived on the outskirts or borders of a settlement or region.
One of the earliest recorded instances of the name Kroma can be found in a medieval manuscript from the 12th century, which mentions a farmer named Kroma residing in a village near the present-day city of Krakow, Poland. This document provides valuable insight into the historical prevalence of the name in the region.
During the Middle Ages, the name Kroma appeared in various forms, including Krom, Krome, and Kroma, reflecting the linguistic variations and regional dialects of the time. The name was particularly common in areas that are now parts of Poland, Slovakia, and the Czech Republic.
In the 16th century, a notable figure bearing the surname Kroma was Jan Kroma (1522-1589), a prominent Czech humanist and scholar who made significant contributions to the fields of philosophy and theology. His works were widely circulated and studied throughout Europe during the Renaissance period.
Another noteworthy individual with the surname Kroma was Andrzej Kroma (1670-1743), a Polish military officer and nobleman who served in the Polish-Lithuanian Commonwealth. He is remembered for his bravery and leadership in numerous military campaigns against foreign invaders during the 17th and 18th centuries.
In the 19th century, the name Kroma gained recognition through the works of the Polish writer and poet Józef Kroma (1811-1886), whose literary contributions helped shape the cultural identity of his nation during a period of political turmoil and struggle for independence.
The surname Kroma has also been associated with various place names throughout Central and Eastern Europe, such as the village of Kromau (now Kromeriz) in the Czech Republic, and the town of Kromolice in southern Poland. These place names likely derived from the same linguistic roots as the surname, further emphasizing its geographical and cultural significance in the region.
Other notable individuals with the surname Kroma include Stanislav Kroma (1892-1976), a Czech artist and painter known for his vibrant landscapes and portraits, and Michal Kroma (1929-2017), a Slovak engineer and inventor who made significant contributions to the field of aerospace technology during the Cold War era.

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.

Does the Census include every surname?
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.
