In simple terms, aging and ageing have the same meaning, definition, and process of growing older. The only real spelling difference comes from American English and British English usage. In the United States, the standard spelling is aging, while the UK, Australia, New Zealand, Canada, and other Commonwealth English regions often prefer ageing.
From my experience editing academic writing, professional writing, and online content, the best rule is to follow your audience, style guide, and language preference. Whether the word works as an adjective, noun, verb, or present participle, both forms carry the same exact meaning and remain an accepted spelling in their proper context.
The history behind this regional spelling comes from English spelling changes, Noah Webster, and later spelling reform efforts in the US. British usage often retains the silent e before adding ing, creating ageing, while American usage usually drops the e, creating aging. You can see this pattern in color/colour, organize/organise, traveling/travelling, and favorite/favourite.
Today, both forms appear in scientific publications, academic publications, healthcare, research, medical writing, marketing, government documents, and everyday communication. Whether discussing an aging population, ageing population, healthy aging, healthy ageing, aging infrastructure, anti aging creams, anti ageing creams, or physical aging, the choice depends on regional preference, writing consistency, and the expectations of your readers.
