Is it because the article's purpose is to explain which of these lady's came first regardless of popularity? I don't think the articles regarding Trump are written for that purpose and so age isn't really even important context to provide. Not to mention he's so well known I don't think they would need to mention his age in every article about him, perhaps if the article was discussing age of politicians as a topic they would mention it, as context is relevant
