A graphic claiming the United Nations has redrawn the boundaries of human age groups has been circulating on Sri Lankan social media again this week. The posts are shared widely on Facebook with a caption telling people not to be fooled by anyone, who calls even someone in 60’s as uncles, citing that UN classifies 18-65 age group as “youth”. Let us look at the claim in detail.
Social Media Posts :
A graphic carrying the UN emblem, claiming to set out a new age classification, has been shared again recently. According to this post, the classification system is:
0-17 = Children
18-65 = Youth
66-79 = Middle Age
80-90 = Elderly
100+ = Old
Numerous other Facebook pages shared the same graphic in the following forms from way back in 2020. Facebook | Archived Link Facebook | Archived Link
Fact-Check :
We checked the official UN website for any record of this classification. We found no section anywhere on the site indicating that the UN had introduced a new age classification of this kind.
We then contacted the Media Unit of the UN Resident Coordinator’s Office in Sri Lanka. They confirmed that the UN has never issued such a classification, and provided the official age definitions currently in use, set out below.
Children Are Defined as Under 18, Not Under 17
People up to age 14 are sometimes referred to as children in casual usage, but Article 1 of the UN Convention on the Rights of the Child defines a “child” as anyone under the age of 18. The UN Resident Coordinator’s Office in Sri Lanka explained that this is deliberate, intended to extend protection and rights to the widest possible age range.
The UN Defines Youth as 15 to 24, Not 18 to 65
The same information appears in the Frequently Asked Questions section of the UN Department of Economic and Social Affairs website, which states that youth are defined as anyone between the ages of 15 and 24. Archived Link.
The UN issued a fact sheet on this age range in 2013, which similarly defines youth as people aged 15 to 24. Un.org | Archived Link. This confirms that the Facebook graphic claiming the UN classifies people aged 18 to 65 as “youth” is false.
Adults Are 25 to 59, and Older Persons Are Generally 60 and Above
Ages 25 to 59 are classified as adult. UNstats.un.org.
The UN refugee agency website also sets out clearly which ages it considers older persons. Unhcr.org | Archived Link. This classification places people generally above the age of 60 in the older persons category.
This Hoax Originated in South Korea
The version of this graphic shared in Sri Lanka appears to have first circulated in South Korea. AFP’s Korean fact-checking team investigated the same claim in English, available here.
Factcrescendo Sri Lanka investigated the claims in Sinhala in 2020 and here is the fact check.

Conclusion :
Our investigation confirms that the Facebook graphic claiming the United Nations recently introduced a new age classification system is false. This applies equally to the version circulating again in 2026 as it did to the version we first investigated in 2021. It is the same recycled graphic.
The UN classifies people under 18 as children, those aged 15 to 24 as youth, those aged 25 to 59 as adults, and those above 60 as older people. There is no UN classification anywhere that defines everyone between 18 and 65 as “youth.”
