Origin
The surname "TILIAKOS" has its origins in Greece, tracing back to the late 18th or early 19th century. It is believed to have derived from the Greek word "tilia," which means "linden tree," indicating a possible connection to a place or region known for the abundance of these trees.
One of the earliest recorded instances of the name TILIAKOS can be found in the village of Kalamata, located in the Peloponnese region of southern Greece. Historical records from the late 1700s mention a family bearing this surname residing in the area, suggesting that this region may have been the initial point of origin.
In the early 1800s, a man named Ioannis TILIAKOS (1789-1867) was documented as a notable figure in the village of Kalamata. He was a respected landowner and played a significant role in the local community during the Greek War of Independence against the Ottoman Empire.
Another notable individual with the surname TILIAKOS was Georgios TILIAKOS (1829-1901), a merchant and trader who lived in the city of Patras. His business ventures extended throughout the Mediterranean region, and he was known for his philanthropic efforts in supporting education and cultural initiatives in his hometown.
During the late 19th century, a branch of the TILIAKOS family settled in the city of Athens. One of its members, Ekaterini TILIAKOS (1856-1932), gained recognition as a pioneering educator and advocate for women's rights. She established one of the first schools for girls in Athens and worked tirelessly to promote equal educational opportunities.
In the early 20th century, Dimitrios TILIAKOS (1878-1954) made a name for himself as a renowned architect. He was responsible for designing several iconic buildings in Athens and other Greek cities, leaving a lasting impact on the country's architectural landscape.
While the surname TILIAKOS may have originated in the Peloponnese region, over time, it has spread to various parts of Greece and beyond, as individuals bearing this name have migrated and established roots in new locations.
Demographics
Among Census respondents with the surname Tiliakos, the largest self-reported group is White at 99.1%. The next largest groups are Two or More Races (0.9%).
The bar chart below shows how Tiliakos 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 Tiliakos 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.
