Census
Lonzo in the 2020 Census
The 2020 Census recorded 1,111 people with the first name Lonzo, which placed it at #11,500 in the published first-name tables. This is a snapshot of people who already had the name at the time of the Census.
The SSA sections elsewhere on this page answer a different question: how often parents gave the name to babies over time. The "people living today" figure on this page is different again: it is a current estimate built from SSA birth records and age-based survival rates, so the two numbers are not expected to match exactly.

Demographics
Ancestry and ethnicity for Lonzo
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Lonzo is Black at 58.0%. The next largest groups are White (28.6%) and Hispanic (8.3%). These figures describe the people who had the name in 2020, not any inherent property of the name itself.
The bar chart below shows how people with the first name Lonzo 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 name, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown so the breakdown is easy to read across every published category. Because the 2020 Census first-name file also includes raw headcounts for each group, Name Census can show those alongside the percentages in the legend and hover tooltip.
Keep in mind that these are self-reported numbers. A first name does not determine a person's race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the name Lonzo at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Lonzo
The name Lonzo is a relatively uncommon given name with roots that can be traced back to the Spanish language. Its origins are believed to stem from the Spanish surname Alonzo, which itself is a variant of the more common name Alfonso. The name Alfonso derives from the Germanic name Adalfuns, which is composed of the elements "adal," meaning noble, and "funs," meaning ready or eager.
In the early medieval period, the name Alfonso was introduced to the Iberian Peninsula by the Visigoths, a Germanic people who ruled portions of the region for several centuries. It gained particular prominence in the Kingdom of Asturias, where it was borne by several notable rulers, including Alfonso I (693-757), often referred to as Alfonso the Catholic.
The earliest recorded instance of the name Lonzo as a given name can be traced back to the 16th century, when it appears in various Spanish records and documents. However, its usage was relatively rare compared to the more common Alfonso and Alonzo.
One of the earliest notable individuals to bear the name Lonzo was Lonzo Naldi (1555-1637), an Italian painter from Bologna who was known for his religious and mythological works. Another prominent figure was Lonzo Cossetti (1620-1693), an Italian architect and sculptor who worked extensively in the city of Genoa.
In the 18th century, Lonzo Geminiano (1720-1795) was an Italian painter and engraver from Bologna, known for his landscapes and vedute (cityscape paintings). Around the same time, Lonzo Smeducci (1745-1820) was an Italian architect and engineer who worked on various projects in Rome and the surrounding areas.
Moving into the 19th century, Lonzo Naldini (1812-1880) was an Italian painter and sculptor from Florence, known for his religious and mythological works. He studied under the renowned Neoclassical sculptor Lorenzo Bartolini.
While the name Lonzo has remained relatively uncommon throughout history, it has persisted as a unique and distinctive given name, particularly in Spanish-speaking regions and among those with Spanish or Italian heritage.

FAQ
Lonzo: questions and answers
How many people in the U.S. are named Lonzo?
Name Census puts the figure at roughly 1,653 living Americans. We arrive at this by taking every SSA birth registration for Lonzo going back to 1880 and adjusting each cohort for expected survival using CDC actuarial life tables. The result is an age-weighted living-bearer count, not a raw birth total. That works out to about 1 in 207,353 US residents.
Is Lonzo a common name?
We classify Lonzo as "Rare". It ranks above 92.9% of all first names in the SSA dataset by living bearers. Across the full history of the data, 3,936 babies have been registered with this name.
When was Lonzo most popular?
The single biggest year for Lonzo was 1919, when 85 babies received the name. The fact that the average living Lonzo is about 56 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Lonzo in the 2020 Census?
The published 2020 Census first-name tables recorded 1,111 people with the name Lonzo, or 0.37 per 100,000 residents. That placed it at #11,500 in the national Census ranking for first names.
Why is the Census count different from the living estimate?
Because they measure different things. The Census figure is a count of people who had the name Lonzo in 2020. The living estimate aims to answer a current question instead: how many people with the name are alive today, based on SSA birth records and age-based survival rates. Since one number is a 2020 snapshot and the other is a present-day estimate, they are not expected to be identical.
What does the Census say about the gender split for Lonzo?
In the 2020 Census sex table, Lonzo appears almost entirely male. Of the 1,116 people counted with this name, 100.0% were male and only a very small share were female. The Census view is a snapshot of people living with the name in 2020, while the SSA section above tracks births across time.
What does the Census say about the background of people named Lonzo?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Lonzo is Black at 58.0%. The next largest groups are White (28.6%) and Hispanic (8.3%). These figures describe the people who had the name in 2020, not any inherent property of the name itself. The percentages in the chart above come from self-reported race and Hispanic-origin responses in the 2020 Census.
Which group reports the name Lonzo most often in the Census?
Black is the largest reported group for people named Lonzo in the 2020 Census, accounting for 58.0% (644 people in the published table).
Why can the Census sex total and race total differ slightly?
The Census Bureau published separate 2020 tables for sex and for race/Hispanic origin, and the released figures can differ slightly because of privacy protection in the public files. That is why this page treats the gender section and the race/origin section as two related snapshots instead of forcing them into one identical total.
Does every first name have Census demographic data?
No. The public Census first-name release only includes names that met the Bureau's publication rules, so many rarer names in the SSA files have no Census demographic snapshot. When that happens, the SSA trend, gender history, and state sections still appear, but the 2020 Census demographic sections are omitted.
What does the SSA popularity chart show?
The chart tracks births, not the number of people alive with the name today. Each point shows how many babies were given the name Lonzo in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Lonzo a male name?
Yes, 100.0% of people registered as Lonzo in the SSA data are male. You can see the full per-sex comparison in the gender distribution section above, which includes the latest year rank, birth count, and peak year for each sex.
Is Lonzo still being used today?
Yes. The SSA still recorded Lonzo in 2024, and the page above shows its latest-year rank where available. A name can be well past its peak and still remain in steady use, especially if it built up a large population over earlier decades.
Why can a name have a lot of living bearers even if it is not trendy now?
Because living-bearer counts and current baby-name popularity measure different things. A name like Lonzo can build up a very large population over many decades, even if fewer parents are choosing it now than they did at its peak.
Where does this data come from?
First-name figures come from the Social Security Administration's national baby name files, which cover every name on a birth certificate from 1880 to 2024. Living-bearer estimates layer in CDC actuarial life tables broken out by sex to account for mortality. The population baseline (342,754,338) is the Census Bureau's latest national estimate.
