Ageism: What It Is, Where It Shows Up, and What It Costs

The word has a birthday. In 1969, psychiatrist Robert N. Butler published "Age-Ism: Another Form of Bigotry" in The Gerontologist and gave the prejudice a name.^[1] Butler argued that contempt for older people should be named and treated as discrimination.

The World Health Organization defines ageism in three parts: stereotypes, how we think about age; prejudice, how we feel about it; and discrimination, how we act on it.^[2] You can carry all three without noticing. Most people do. WHO's estimate is blunt: half the world's population holds ageist attitudes against older people.^[2] That finding comes from the first United Nations global report on ageism, published by WHO in March 2021.^[3]

Ageism runs in both directions. Young workers get written off as entitled and unserious. But the weight lands on the old, and it lands hardest in the two rooms where people can least afford it: the interview and the exam.

Ageism is prejudice against older people. If you're lucky enough to grow old, the stereotypes you tolerate now can shape how you're treated later.

Age-based stereotypes can affect hiring, healthcare, public policy, media, and the way older people are treated in ordinary life. They also shape how people understand their own aging.

Congress banned age discrimination at work in 1967. The Age Discrimination in Employment Act protects everyone 40 and older, and it covers hiring, firing, pay, job assignments, promotions, layoffs, training, and benefits.^[4] The law turns 59 this year. The problem hasn’t retired.

In fiscal year 2025, workers filed 16,353 age discrimination charges with the Equal Employment Opportunity Commission.^[5] That figure counts only people who filed a federal charge. Most people who lose a job or an interview to their age file nothing, because proving age bias is hard and few want to sue an industry they still need work from.

Surveys get closer to the real size. In January 2026, AARP published a survey of 1,656 workers age 50 and older, conducted in mid-2025. It found that 64 percent had seen or experienced age discrimination at work. Among those workers, 91 percent said age discrimination against older workers is common.^[6] The specifics they reported:

• 33 percent were assumed to be less capable with technology.
• 24 percent were treated as resistant to change.
• 21 percent heard jokes aimed at their generation.
• 20 percent had their accomplishments or expertise go unacknowledged.
• 20 percent were passed over for training that went to younger workers.
• 22 percent felt they were being pushed out of their jobs.^[6]

Workplace ageism follows a script: your experience is obsolete, your salary is a target, and your knowledge is welcome only on your way out. We covered the knowledge part in When the Culture Stops Listening to Older People, and what the clock does to people who find their real work late in The Career Trap.

The most dangerous three words in the medicine of old age are "it's just age." Fatigue at 75 gets a shrug where fatigue at 45 gets a workup. Depression gets read as reasonable sadness. Pain gets read as the admission price of being old. Underneath, the treatable condition keeps advancing.

This has been measured. In 2020, a Yale team led by Becca Levy published a systematic review of ageism and health covering 422 studies from 45 countries and more than 7 million participants across 25 years. In 95.5 percent of those studies, ageism came with worse health outcomes for older people. And in 84.6 percent of the studies that looked at access to care, age itself dictated who received certain procedures and treatments.^[7] Not prognosis. Not the patient's own wishes. Age.

The bill has been added up. WHO cites a United States estimate that ageism accounted for $63 billion in health care costs in a single year, across eight major health conditions.^[2] That's money spent treating harm the prejudice itself helped create, and it's an undercount, since it covers only eight conditions in one country.

If you're managing care for an older parent, our end-of-life care guide covers how to keep clinicians looking for answers instead of reaching for the shrug.

Between the interview and the exam room sits the culture, and the culture mostly handles old age by removing it from view. Count the speaking roles for characters over 70 in this year's television that aren’t about dementia, death, or being a burden. Walk the birthday card aisle: past 50, the jokes are decline, sagging, and forgetting.

The beauty industry's favorite word is "anti-aging," a term that treats a universal biological process as a disease you should be ashamed of catching. The same erasure runs through advertising, which still chases the under-50 demographic, and through stock photography, where "older adult" too often means a pair of hands resting on a cane.

None of this needs a statistic to be visible. The message is consistent: aging is failure, and the polite thing to do with the people furthest along in it isn’t to show them. Invisibility isn’t neutral. It's how a culture practices forgetting people before they die.

The strangest finding in ageism research concerns what the prejudice does after you absorb it about yourself.

In 2002, Becca Levy and colleagues published a study in the Journal of Personality and Social Psychology that followed 660 people age 50 and older from the Ohio Longitudinal Study of Aging and Retirement. Their attitudes about their own aging had been recorded up to 23 years earlier, and the researchers matched them against the National Death Index.

People with more positive views of their own aging lived 7.5 years longer than people with more negative views. The gap held after controlling for age, gender, socioeconomic status, loneliness, and functional health.^[8]

Seven and a half years. WHO uses the same figure when it lists ageism's costs: earlier death, by 7.5 years.^[2] The 2020 review reinforced it. All 10 studies that examined ageism and lifespan found ageism predicted a shorter one.^[7]

The mechanism isn’t mystical. People who believe old age is nothing but decay act on the belief. The checkup gets skipped because decline feels inevitable anyway. The daily walk stops. Every misplaced key gets read as the beginning of the end. Levy's data showed the survival effect was partially explained by will to live.^[8] What you expect from your later years changes how you behave in them, and how you behave changes how many of them you get.

The WHO global report reviewed what actually reduces ageism and found three strategies with evidence behind them: policy and law, educational interventions, and intergenerational contact.^[2][3]

• Law and policy. Enforced anti-discrimination rules change behavior before they change minds. The 16,353 charges filed last year exist because a 1967 law gives workers somewhere to file them.^[5]
• Education. Most ageist beliefs are factually wrong, and correcting them reduces the prejudice. Teaching what aging actually does, and doesn’t do, to memory, productivity, and desire strips the stereotype of its material.
• Contact. Sustained contact between generations, as equals rather than as caretaker and patient, is among the best-tested interventions. It's hard to hold a stereotype about a person you actually know.

Two more belong on the list, even if they fit less neatly into a program. Purpose: a society that pushes people out of visible roles at 65 manufactures its own evidence that older people contribute nothing. Keeping older people in work, mentorship, and public life is the most direct counterargument available.

And naming: Butler's entire contribution was a word. Prejudices with names can be confronted. Prejudices without names pass as common sense. When a doctor stops investigating, when a recruiter says "overqualified," when you catch yourself deducting competence from gray hair, say the word.

Then remember whose side you're on. Fighting ageism is advance work on your own behalf. Every stereotype you leave standing today will be waiting for you on the day you arrive.
