How to Verify a Politician's Age: A Practical Guide
Figuring out how old a politician is sounds trivial until you actually try to do it properly. Most people just check Wikipedia, which is usually correct but also usually sourced from somewhere else. If you want to do this right, here is the actual process I use. The fundamental method is simple: find an authoritative primary source for the birth date, then calculate. Primary sources in the American context mean a hospital-issued birth certificate, a certified copy on file with a government entity, or a census record. Everything else is secondary and potentially wrong. I once spent three weeks trying to verify the birth date of a state-level candidate whose family had immigrated in the 1970s. The name on the passport didn't match the name on the school records, and the birth certificate listed a different date than the local newspaper's coverage of his graduation. What I ended up doing was pulling the candidate's voter registration record, which typically requires a date of birth to register, then cross-referencing that with the census record from ten years prior. The two matched. The newspaper had the year wrong by one. This kind of mismatch happens more often than you would think, especially with older politicians or those born outside the United States.
For Donald Trump, the process is straightforward because his birth date is well-documented and has been publicly verified. He was born on June 14, 1946. His birth certificate was made public during the 2012 presidential cycle when he released it to the Associated Press. That is as close to a primary source as you get in American politics. Census records from 1950 and 1960 list him at his correct age. Voter registration records in New York confirm the same date. The calculation is simply the difference between June 14, 1946 and today. When you are verifying a politician's age, the most common pitfall is relying on a single source. A campaign website will list a birth year that may not match the actual year. Social media profiles are almost never reliable. A news article from 2004 might say he was 57 when he was actually 58. Always go to the primary document if possible. Another issue that people run into is the difference between the Gregorian calendar and older calendars. Some politicians were born in countries that hadn't adopted the Gregorian calendar yet, or in regions where the official record used a different system. This is rare for American politicians but comes up frequently if you are researching international figures. If the birth country switched calendar systems after the person was born, the recorded date might not match what you expect without adjustment.
The biggest limitation of this approach is accessibility. Not every politician's birth certificate is public. Many states treat birth certificates as confidential records that only the individual or their legal representatives can request. Once a politician leaves office, those records generally do not become automatically public. This means for many lesser-known politicians, you are working with whatever secondary sources are available, which brings us back to the reliability problem. If a politician has never been photographed holding a birth certificate or had their records scrutinized by news organizations, the best you can do is triangulate. Check census data, check voter registration if your state makes those available, check school records that might appear in local archives, and then compare all of them. When three independent sources agree, you have a strong result. When they do not, you need to dig further or acknowledge the uncertainty. For Trump specifically, there is essentially no uncertainty. The birth certificate, census records, and public documentation all align. He is calculated from a confirmed birth date with no known dispute. Most politicians do not have that level of verification on public record, and that is the reality you are working with in this field.

The actual calculation itself takes about twenty seconds once you have the date. The hard part is finding a date you can trust. I usually spend more time on source verification than on anything else. In practice, a proper age verification for a well-documented figure like Trump takes maybe ten minutes total. For an obscure local candidate with incomplete records, it can take several days or end with a note that the exact date cannot be confirmed.
