Origin
The surname "LEYBA" has its origins in Spain, dating back to the medieval period. It is believed to have derived from the Spanish word "leiva," which means "yeast" or "leaven." This surname was likely initially given to someone who worked as a baker or had some connection to the baking trade.
One of the earliest recorded instances of the surname can be found in the 13th-century manuscript "Cartulario de Valpuesta," where a certain Martín Leyba is mentioned. This document suggests that the name was already in use during that time in the northern region of Spain.
In the 15th century, the surname appears in various historical records from the province of León, such as the "Libro de la Montería" compiled by King Alfonso XI. This book, which documented hunting activities, mentions several individuals with the surname Leyba, indicating that the name had spread across different regions of Spain.
During the 16th and 17th centuries, the surname Leyba gained prominence in Spain, with several notable individuals bearing this name. Juan de Leyba (1518-1598) was a renowned Spanish architect who worked on several important projects, including the renovation of the Alcázar of Segovia.
Another notable figure was Pedro de Leyba (1570-1635), a Spanish military officer and explorer who participated in the conquest of Chile and served as the governor of the territory between 1617 and 1625.
As the Spanish Empire expanded across the Atlantic, the surname Leyba was carried to the Americas, where it took root in various regions, particularly in Mexico and parts of South America. One of the earliest recorded instances of the name in the New World is that of Rodrigo de Leyba, a Spanish settler who established a hacienda in what is now Colombia in the late 16th century.
In the 18th century, José de Leyba (1730-1810) was a prominent Spanish military engineer who oversaw the construction of several fortifications in the Caribbean, including the Castillo de San Pedro de la Roca in Santiago de Cuba.
Throughout its history, the surname Leyba has undergone various spelling variations, such as Leiva, Leyva, and Lleyva, reflecting the regional dialects and linguistic influences in different parts of Spain and Latin America.
Demographics
Among Census respondents with the surname Leyba, the largest self-reported group is Hispanic at 77.9%. The next largest groups are White (15.0%) and Asian/Pacific Islander (3.4%).
The bar chart below shows how Leyba 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 Leyba 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.
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.
