Origin
The surname Calafell has its roots in the Catalonian region of Spain. It is derived from the place name Calafell, a municipality located in the province of Tarragona, Catalonia. The name likely originated in the medieval period, around the 11th or 12th century.
Calafell is believed to have stemmed from the Latin word "calefactus," which means "heated" or "warmed." This suggests that the place name may have been associated with a location known for its warm climate or perhaps the presence of natural hot springs.
Early records of the Calafell surname can be found in various historical documents from the region, including municipal archives and ecclesiastical records. One of the earliest known mentions of the name dates back to the 13th century, when a certain Pere de Calafell was recorded as a landowner in the area.
In the 15th century, the Calafell family played a significant role in the defense of the region during the Catalan Civil War. Joan de Calafell, born in 1421, was a prominent military leader who fought against the forces of King Juan II of Aragon.
Another notable figure bearing the Calafell surname was Francesc de Calafell, a 16th-century Catalan playwright and poet. His works, written in the Catalan language, contributed to the cultural renaissance of the region during that time period.
In the 17th century, Miquel de Calafell y Borrell (1617-1694) was a distinguished Catalan jurist and legal scholar. He authored several influential treatises on Catalan civil law and served as a magistrate in Barcelona.
Fast-forwarding to the 19th century, Joaquim de Calafell (1820-1891) was a prominent Catalan architect and urban planner. He was responsible for designing numerous notable buildings and public spaces in Barcelona, including the iconic Parc de la Ciutadella.
Throughout history, the Calafell surname has been closely associated with the Catalonian region of Spain, reflecting its deep roots and cultural significance within that area.
Demographics

The bar chart below shows how Calafell 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 Calafell 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.
