Origin
Meaning and origin of Chaidez
The surname Chaidez has its origins in Spain, with the earliest records dating back to the 16th century. The name is believed to have originated from the Spanish region of Extremadura, specifically in the town of Chaidez or Chaydez. The name is thought to be derived from the Latin word "caedere," which means "to cut" or "to fell," suggesting that the earliest bearers of this name may have been woodcutters or lumberjacks.
In the 16th century, the name Chaidez appeared in various historical documents, including land registry records and census documents from the region of Extremadura. One of the earliest recorded mentions of the name was in a land grant document from 1542, where a certain Pedro Chaidez was granted a parcel of land in the town of Chaidez.
The name Chaidez has also been found in some historical manuscripts, such as the "Libro de Bautismos" (Book of Baptisms) from the parish of Santa María de Chaidez, which dates back to the late 16th century. This document recorded the baptisms of several individuals with the surname Chaidez, indicating that the name was well-established in the region by that time.
Over the centuries, the name Chaidez has been associated with several notable individuals. One of the earliest recorded individuals with this surname was Juan Chaidez, a Spanish explorer who accompanied Hernán Cortés on his expedition to Mexico in the early 16th century. Another notable figure was Alonso Chaidez, a Spanish military officer who served in the Spanish army during the 17th century and played a role in the conquest of parts of South America.
In the 18th century, the name Chaidez was carried by Diego Chaidez, a prominent Spanish architect who designed several notable buildings in Madrid and other parts of Spain. During the same period, María Chaidez was a renowned Spanish painter whose works were highly sought after by the nobility and aristocracy of the time.
In the 19th century, the name Chaidez was borne by José Chaidez, a Spanish writer and poet who gained recognition for his literary works that explored themes of love, nature, and the human condition. His poetry collections, published in the mid-1800s, were widely acclaimed and contributed to the cultural renaissance of the time.
While the surname Chaidez originated in Spain, it has since spread to various parts of the world, particularly to Latin American countries, due to Spanish colonization and migration. However, the earliest and most significant historical references to this name can be traced back to its roots in the Spanish region of Extremadura.

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

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Chaidez (2000, 2010, 2020).
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.
