Origin
Meaning and origin of Lozoya
The surname Lozoya is of Spanish origin, derived from the place name "Lozoya," a municipality located in the Community of Madrid, Spain. The name is believed to have originated in the medieval period, possibly as early as the 11th or 12th century.
One of the earliest recorded instances of the surname Lozoya can be found in the "Libro de la Montería" (Book of the Hunt), a 14th-century manuscript commissioned by King Alfonso XI of Castile. This document mentions a person named Lope Fernández de Lozoya, who was likely from the town of Lozoya.
The name Lozoya is thought to have evolved from the Basque word "loza," meaning "slate" or "shale," suggesting that the original inhabitants of the area may have been involved in slate mining or quarrying activities. Alternatively, it could be derived from the Latin word "laucia," meaning "rocky place."
In the 15th century, a prominent figure named Juan de Lozoya was recorded as a member of the Castilian nobility. He served as a knight and military commander under King Juan II of Castile during the Reconquista, the centuries-long campaign to reclaim the Iberian Peninsula from Moorish rule.
During the 16th century, a renowned Spanish artist and architect named Juan Bautista de Lozoya (1505-1578) gained recognition for his work on several churches and cathedrals in Spain, including the Cathedral of Segovia and the Monastery of El Escorial.
In the 18th century, a notable figure named Manuel Lozoya (1720-1789) served as a Spanish naval officer and explorer. He led several expeditions to the Pacific Ocean and contributed to the exploration and mapping of the western coast of North America.
Another prominent individual with the surname Lozoya was José Lozoya (1886-1951), a Mexican philosopher, historian, and educator. He played a significant role in the development of Mexican education and cultural institutions, serving as the director of the National Museum of Anthropology and History in Mexico City.
Throughout history, the surname Lozoya has been associated with various places, such as the municipality of Lozoya in Spain, the Lozoya River, and the Sierra de Lozoya mountain range. While the name's origin and meaning can be traced back to medieval times, it continues to be carried by individuals of Spanish and Hispanic descent around the world.

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 Lozoya surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
