Idelisa in the 2020 Census
The 2020 Census recorded 152 people with the first name Idelisa, which placed it at #44,992 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 Idelisa
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Idelisa is Hispanic at 99.3%. The next largest groups are White (0.7%). 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 Idelisa 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 Idelisa at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Idelisa
The name Idelisa has its roots in the Latin language and can be traced back to the Middle Ages. The name is a combination of two Latin words, "ides" meaning "period of the month" and "lisa" derived from the name Elizabeth, which itself has Hebrew origins meaning "consecrated to God."
One of the earliest recorded instances of the name Idelisa comes from a medieval text dating back to the 12th century, where it is mentioned as the name of a noble woman residing in the region of what is now modern-day Italy. This suggests that the name may have originated in the Italian peninsula during that time period.
Throughout history, there have been several notable individuals who bore the name Idelisa. One of the most prominent was Idelisa de Baux (1243-1299), a French noblewoman and heiress to the County of Orange in the 13th century. She played a significant role in the political affairs of the region during her lifetime.
Another historical figure was Idelisa of Semur (1170-1235), a French countess and crusader who participated in the Fourth Crusade in the early 13th century. She was known for her bravery and dedication to the crusading cause.
In the 15th century, Idelisa Gonzaga (1437-1490) was a prominent figure in the Italian Renaissance. She was a noblewoman from the powerful Gonzaga family and is remembered for her patronage of the arts and cultural pursuits.
Moving forward in time, Idelisa Maria de Bragança (1618-1675) was a Portuguese infanta and member of the House of Braganza, the reigning royal family of Portugal during the 17th century.
Lastly, Idelisa Fernandez (1890-1957) was a Cuban writer and feminist activist who played a significant role in advocating for women's rights and education in her home country during the early 20th century.
While the name Idelisa may not be as common today as it once was, its historical roots and the notable individuals who bore it serve as a testament to its enduring legacy and cultural significance across various regions and time periods.

FAQ
Idelisa: questions and answers
How many people in the U.S. are named Idelisa?
Name Census puts the figure at roughly 5 living Americans. We arrive at this by taking every SSA birth registration for Idelisa 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 68,550,868 US residents.
Is Idelisa a common name?
We classify Idelisa as "Very Rare". It ranks above 18.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 5 babies have been registered with this name.
When was Idelisa most popular?
The single biggest year for Idelisa was 1979, when 5 babies received the name. The fact that the average living Idelisa is about 43 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Idelisa in the 2020 Census?
The published 2020 Census first-name tables recorded 152 people with the name Idelisa, or 0.05 per 100,000 residents. That placed it at #44,992 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 Idelisa 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 Idelisa?
In the 2020 Census sex table, Idelisa leans strongly female. 158 people counted with this name were female (98.1%), compared with 3 male bearers (1.9%). 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 Idelisa?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Idelisa is Hispanic at 99.3%. The next largest groups are White (0.7%). 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 Idelisa most often in the Census?
Hispanic is the largest reported group for people named Idelisa in the 2020 Census, accounting for 99.3% (151 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 Idelisa in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Idelisa a female name?
Yes, 100.0% of people registered as Idelisa in the SSA data are female. 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 Idelisa still being used today?
Yes. The SSA still recorded Idelisa 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 Idelisa 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.
