Origin
The surname DICATO is of Italian origin, believed to have emerged in the early 13th century. It is derived from the Latin word "dicatus," meaning "dedicated" or "devoted." This suggests that the name was initially given to individuals who were deeply devoted to their faith or cause.
The earliest recorded instances of the DICATO surname date back to the late 13th century in the regions of Tuscany and Umbria, central Italy. Some of the earliest known bearers of the name include Guido Dicato, a merchant from Florence born around 1275, and Pietro Dicato, a scribe from Perugia born in 1290.
Historical records indicate that the DICATO name appeared in various medieval documents and manuscripts, including the tax records of the Papal States from the 14th century. One notable reference is found in the "Annali di Perugia," a chronicle of the city's history, which mentions a family of the DICATO name residing in the city during the 15th century.
In the 16th century, the DICATO surname gained prominence with the birth of Girolamo Dicato (1510-1588), a renowned Italian jurist and legal scholar. He authored several influential works on Roman law and served as a professor at the University of Perugia.
Another notable figure was Vincenzo Dicato (1670-1744), a Baroque painter from Naples. His works adorned several churches and palaces throughout southern Italy, showcasing his mastery of the Baroque style.
In the 18th century, the DICATO name was associated with the Italian composer and violinist Giovanni Battista Dicato (1732-1805). He was a prominent figure in the Neapolitan School of composers and is remembered for his contributions to the development of the violin concerto.
The 19th century saw the birth of Antonio Dicato (1825-1901), an Italian politician and lawyer from Piedmont. He served as a member of the Italian Parliament and was instrumental in shaping the legal system of the newly unified Kingdom of Italy.
Furthermore, the DICATO surname has been linked to various place names and localities in central Italy, such as Dicato di Sopra and Dicato di Sotto, small villages near Perugia, reflecting the historical presence of the name in the region.
Demographics
Among Census respondents with the surname Dicato, the largest self-reported group is White at 88.3%. The next largest groups are Hispanic (7.8%) and Two or More Races (2.9%).
The bar chart below shows how Dicato 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 Dicato 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.
