Origin
The surname Mejia is of Spanish origin, and it is believed to have originated in the region of Extremadura, Spain, during the Middle Ages. The name is thought to be derived from the Spanish word "mejía," which means "boundary" or "border." This suggests that the name was likely given to someone who lived near a boundary or border area.
In the early 13th century, the name Mejia can be found in various historical records from Extremadura, such as the Tumbo Prieto de la Catedral de Badajoz, a manuscript containing documents related to the Cathedral of Badajoz. One of the earliest recorded instances of the name is Juan Mejía, a nobleman who lived in the village of Villanueva de la Serena in the 1240s.
As the name spread throughout Spain, it also found its way to the Spanish colonies in the Americas. One notable early bearer of the name was Hernán Mejía Miraval, a Spanish conquistador who participated in the conquest of Mexico alongside Hernán Cortés in the 16th century.
In the 17th century, the Mejia family had a significant presence in the region of Nueva España (present-day Mexico). Juan Mejía de Sandoval (1595-1668) was a prominent figure in the Catholic Church, serving as Bishop of Chiapas and later as Bishop of Puebla.
Another notable individual with the Mejia surname was José María Mejía (1778-1813), a Mexican military officer who fought against the Spanish during the Mexican War of Independence. He was executed by the Spanish authorities for his role in the rebellion.
In the 19th century, one of the most famous bearers of the Mejia name was Tomás Mejía (1820-1867), a Mexican general who fought in various conflicts, including the Mexican-American War and the Reform War. He was executed by the forces of Emperor Maximilian I after being captured during the Battle of El Cubilete.
The surname Mejia has also been associated with various place names in Spain and Latin America. For example, there is a town called Mejías in the Spanish province of Badajoz, and a municipality called Mejía in the Colombian department of Antioquia.
Demographics
Among Census respondents with the surname Mejia, the largest self-reported group is Hispanic at 93.9%. The next largest groups are White (3.6%) and Asian/Pacific Islander (1.4%).
The bar chart below shows how Mejia 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 Mejia 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.
