Origin
The surname Moscoso originated in the northwestern region of Spain, particularly in the province of Galicia. It can be traced back to the Middle Ages, around the 12th or 13th century. The name is believed to derive from the Galician-Portuguese word "musgo," meaning "moss" or "lichen," possibly indicating a connection to a place abundant in these types of vegetation.
One of the earliest recorded instances of the Moscoso name appears in the Tumbo Viejo de Castilla, a medieval cartulary from the 13th century. It mentions a nobleman named Rodrigo Moscoso who held lands and properties in the region of Galicia. The name also appears in various other historical documents from that period, such as land grants and property deeds.
The Moscoso family played a significant role in the history of Galicia and Spain during the Middle Ages and beyond. One notable figure was Pedro Moscoso, a military commander who fought alongside King Ferdinand III in the Reconquista, the Christian reconquest of the Iberian Peninsula from the Moors. He was born around 1190 and participated in the conquest of Seville in 1248.
Another prominent member of the Moscoso family was Álvaro Moscoso, a 15th-century nobleman and diplomat who served as the ambassador of Castile to the Holy Roman Empire. He was born in Galicia around 1420 and played a crucial role in the negotiations that led to the marriage of Philip the Handsome, the son of Emperor Maximilian I, and Joanna of Castile, known as Joanna the Mad.
In the 16th century, the Moscoso name gained prominence in the Americas due to the involvement of several members of the family in the Spanish conquest and colonization efforts. One noteworthy figure was Alonso Moscoso, a conquistador and explorer who participated in the expedition led by Hernando de Soto to explore and conquer parts of present-day Florida, Georgia, and the Southeastern United States. He was born in Galicia around 1510.
Another notable Moscoso was Juan Moscoso, a Spanish conquistador and explorer who led an expedition to explore parts of present-day New Mexico and Texas in the late 16th century. He was born in Galicia around 1550 and is credited with establishing the first European settlement in the region, known as San Gabriel del Yungue, near present-day El Paso, Texas.
The Moscoso surname has persisted throughout history and can still be found in various parts of Spain, as well as in Latin American countries with Spanish heritage, such as Mexico, Argentina, and Colombia. It serves as a testament to the rich cultural and historical legacy of the Galician region and its influential families during the medieval and colonial periods.
Demographics
Among Census respondents with the surname Moscoso, the largest self-reported group is Hispanic at 86.8%. The next largest groups are White (7.0%) and Asian/Pacific Islander (4.8%).
The bar chart below shows how Moscoso 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 Moscoso 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.
