Origin
The surname Molinari has its origins in Italy, specifically in the northern regions of Lombardy and Piedmont. It is derived from the Italian word "molinaro," which means "miller" or someone who operates a mill. The earliest recorded instances of this surname date back to the 13th century.
During the Middle Ages, the Molinari family was well-established in the city of Milan, where they were involved in the milling industry. Records from this period show that several members of the family held influential positions within the city's guilds and trade organizations.
One notable figure from this era was Giovanni Molinari, a prominent merchant and banker who lived in Milan in the late 14th century. His name appears in several historical documents related to trade agreements and financial transactions.
As the Molinari family grew and spread throughout northern Italy, variations in the spelling of the surname began to emerge. Some of these variations include Molinaro, Molinaroli, and Molinelli. In some cases, the name was also associated with specific locations, such as Molinari di Bergamo or Molinari di Torino.
During the Renaissance period, the Molinari family produced several notable figures, including the architect and sculptor Gian Giacomo Molinari, who was born in Genoa in 1570. His works can be found in various churches and palaces throughout northern Italy.
Another prominent individual was Giambattista Molinari, a Venetian philosopher and economist who lived from 1801 to 1888. He is considered one of the founders of the economic theory of anarcho-capitalism and was a strong advocate for free market principles.
In the 19th century, the Molinari name gained international recognition through the works of the Italian composer and pianist Giovanni Molinari (1805-1881). His compositions, which included operas, symphonies, and chamber music, were widely performed throughout Europe.
One of the most famous bearers of the Molinari surname was the Italian painter and sculptor Medardo Rosso (1858-1928), whose full name was Giovanni Battista Medardo Rosso Molinari. He was a pioneering figure in the Impressionist and Modernist movements and is renowned for his sculptural works in wax and plaster.
Throughout its long history, the Molinari surname has been carried by individuals from various walks of life, including artists, intellectuals, entrepreneurs, and tradespeople. While its origins can be traced back to the milling industry of medieval Italy, the name has since spread across the globe, reflecting the diverse and far-reaching impact of Italian culture and heritage.
Demographics
Among Census respondents with the surname Molinari, the largest self-reported group is White at 83.8%. The next largest groups are Hispanic (12.4%) and Two or More Races (1.8%).
The bar chart below shows how Molinari 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 Molinari 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.
