One of the earliest recorded instances of the name can be found in the Liber Beneficiorum, a 15th-century ecclesiastical registry of benefices and prebends in the Archdiocese of Gniezno, Poland. The name appears as "Swiat" in this document, suggesting its use during that time period.
In the 16th century, the name "SWIAT" can be found in the Polish Metrical Books, which were records of baptisms, marriages, and burials maintained by various parishes across the country. These records provide valuable insights into the geographical distribution of the name, indicating its presence in various regions of Poland.
Notable individuals bearing the surname "SWIAT" include Stanisław Świat (1900-1969), a Polish painter and graphic artist known for his landscapes and portraits. Another prominent figure was Kazimierz Świat (1914-2004), a Polish military officer who served during World War II and later became a diplomat.
The name "SWIAT" has also been found in historical records from other parts of Europe, suggesting potential migration patterns. For instance, in the 18th century, there are records of individuals with the surname "Swiat" residing in the German city of Königsberg (now Kaliningrad, Russia).
It is worth noting that variations of the name's spelling existed, such as "Świat," reflecting the linguistic evolution and regional differences within Poland.

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.
