Origin
The surname Morozov originated in Russia and dates back to the 14th century. It is a patronymic name, derived from the Russian word "moroz," meaning "frost." Morozov translates to "son of Moroz," suggesting that the name may have initially referred to someone whose father was known for being associated with cold or winter weather.
The name's earliest recorded appearance can be found in medieval Russian manuscripts, where various spellings such as "Morozov," "Morozoff," and "Morozowicz" were used. These variations likely reflected regional dialects and linguistic influences from other Slavic languages.
One of the earliest known bearers of the name was Ivan Morozov, a wealthy merchant and landowner who lived in the 16th century. Records show that he owned extensive properties in the city of Veliky Novgorod and played a significant role in the city's economic and political affairs.
In the 17th century, the Morozov family gained prominence in Moscow, with several members holding influential positions in the Russian Orthodox Church and the Tsar's court. Notably, Boris Morozov (1590-1661) served as a boyar (nobleman) and a close advisor to Tsar Alexis I.
Another notable figure with the surname Morozov was Savva Morozov (1770-1862), a successful industrialist and textile manufacturer who established one of the largest textile mills in Russia. His business empire contributed significantly to the country's industrial development in the 19th century.
During the Russian Revolution, the Morozov family faced persecution and many of their assets were seized by the Bolshevik government. However, some members of the family managed to flee Russia and establish themselves in other parts of the world, carrying the name with them.
In more recent history, Mikhail Morozov (1897-1952) was a Soviet military commander who played a crucial role in the defense of Moscow during World War II. He was awarded the title of Hero of the Soviet Union for his bravery and leadership.
While the surname Morozov has its roots in Russia, it has since spread to other countries through immigration and cultural exchange. Today, individuals bearing this name can be found in various parts of the world, reflecting the rich history and global reach of this once distinctly Russian surname.
Demographics
Among Census respondents with the surname Morozov, the largest self-reported group is White at 95.3%. The next largest groups are Two or More Races (1.9%) and Hispanic (1.3%).
The bar chart below shows how Morozov 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 Morozov 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 Morozov (2000, 2010, 2020).
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.
