Is Ilo getting more or less popular?
Ilo is too rare for a direction to mean much. It averaged 11 births a year across 2021–2025 against 8 a year a decade earlier — at these counts a single baby moves the percentage, and any year under five births is withheld at source.
Measured on recorded births. American births overall have fallen since 2007, so most established names lose births over any recent decade — a name can shed births and still hold its rank. Compare the rank above, which is measured against the other names of the same year.
Is Ilo a boy’s or a girl’s name?
Across the whole record Ilo is mostly a girl’s name — 91.4% of the 779 Americans given it were girls and 8.6% were boys. In births since 2016 it is 23% girls and 77% boys.
Counted from every US birth the Social Security Administration recorded under this name, so it reflects use rather than opinion. A name given to fewer than five babies of one sex in a year is withheld at source and is not counted.
How old is someone named Ilo?
Roughly 109 Americans named Ilo are alive today — 14% of everyone ever recorded with the name. The median is 8 years old, and half are between 2 and 85. That is a wide band, the mark of a name in steady use across generations rather than a passing fashion.
An estimate, not a count. Recorded births are carried forward through the Social Security Administration’s 2023 period life table, by age and sex. That table describes mortality in one recent year, so it credits the oldest cohorts with today’s survival rather than the harsher rates they actually lived through — the further back a name peaked, the more this will overstate how many remain. It counts people issued a Social Security number at birth, not immigrants who arrived later.
