The most unhappy age, according to extensive research on the "happiness curve," often centers around the late 40s, with specific studies pinpointing around age 47 or 49 as the nadir of well-being, a period marked by midlife challenges and declining happiness before it generally improves in the 50s and 60s. This midlife low point, often called the "midlife crisis", sees increased depressive symptoms and general unhappiness, though it varies by individual and generation, with some younger people now experiencing lows earlier.
A huge research study concluded that in developed countries, people start having decreasing levels of happiness starting at age 18. It continues in their 20s and 30s before reaching an unhappiness peak — or bottoming out, if you prefer — at the precise age of 47.2. That's exactly how old I am today.
Surprising Science: The 2 Ages When People Are Happiest
According to a study by the London School of Economics and Political Science, happiness tends to peak not once, but twice in life: first at age 23, and again at age 69. Yes—69!
The observed age pattern for daily stress was remarkably strong: stress was relatively high from age 20 through 50, followed by a precipitous decline through age 70 and beyond.
Unhappiness is hill-shaped in age and the average age where the maximum occurs is 49 with or without controls.
According to researchers at Harvard, the age of 35 is the happiest, as that's when most of us begin to stabilise our lives, reach professional heights, and have stronger social ties—all of which contribute to our sense of total fulfilment.
There are a lot of different reasons why you might feel like nothing makes you happy. Certain mental health conditions like depression, anxiety, and PTSD can cause severe feelings of unhappiness, lack of motivation, and disinterest in activities that used to bring joy.
In it, he talks about how the ages of 22–42 are statistically the most unhappy period in life. Why? People come out of their early 20s and think life is supposed to be easy, but it's not. Those two decades are full of challenges.
Recent research shows that members of the Baby Boomer generation have worse health than previous generations did at the same ages—diabetes, heart disease and other chronic illnesses are more common.
Quality of life increases from 50 years (CASP‐19 score 44.4) to peak at 68 years (CASP‐19 score 47.7). From there it gradually starts to decline, reaching the same level as at 50 years by 86 years. By 100 years, CASP‐19 score has declined to 37.3.
They also found that happiness across lifespan exists on a spectrum of valleys and peaks over time: Satisfaction with life declines between ages nine and 16, rises to reach its peak at age 70, then declines again until age 96 (the oldest age recorded in the study).
This knowledge about happiness states that 50% of our happiness is determined by genetics, 10% by our circumstances and 40% by our internal state of mind. This rule originates from the book “The How Of Happiness” written by Sonja Lyubomirsky. A lot of people and even psychologists live by this rule.
According to this unscientific survey, most women peak between 19.9 years and 24.0 years (sample size 22).
Across much of the world, it is no longer middle-aged adults who are the most miserable. Instead, young people, especially Gen Z, are reporting the highest levels of unhappiness of any age group.
At What Age Is Depression Most Common? According to CDC data from 2019, 21% of adults experiencing any depressive symptoms in the most recent two weeks were between 18 and 29 years old. This incidence is the largest among all adult age groups.
Empirical Research
Empirical studies have found that blacks have lower life satisfaction, less trust in people, less general happiness, less marital happiness, more anomie, and lower self-rated physical health than whites (Thomas and Hughes 1986; Barger, Donoho, and Wayment 2008).
Some consider millennials to be one of the heaviest generations. In the U.K., researchers found at least seven in 10 people born in the millennial generations will be overweight or obese before they reach middle age. Baby boomers only faced rates of five in 10.
Whilst boomers and millennials may use the 😂 emoji, this has long since been deemed 'uncool' (or 'cheugy') by Gen Z. Instead, this has been replaced by the skull (💀) or the crying emoji (😭), dramatising the idea of 'dying with laughter'.
“Often referred to as the 'unluckiest generation,”millennials have had to adapt to rising costs of living and an unpredictable job market during their most formative career years.
Key Insights on Life Expectancy
In 2021, the global average life expectancy was just over 70 years. This is an astonishing fact – because just two hundred years ago, it was less than half. This was the case for all world regions: in 1800, no region had a life expectancy higher than 40 years.
Studies show the saddest age is actually 47. That's when people often start facing mid-life crises and really noticing how quickly time is flying by. Bobby even shared his own recent mortality crisis: realizing he may never see his beloved Arkansas Razorbacks win a championship in his lifetime.
The "most dangerous age" is 15 years. During a single year here, referrals to the Youth Aid Bureau of the Milwaukee Police Department were headed by 15-year-olds - a total of 2,990. Referral of 16-year-olds was second highest, totaling 2,813.
Five common signs of poor mental health include persistent sadness or extreme mood swings, withdrawing from friends and activities, significant changes in sleep or appetite, difficulty concentrating or coping with daily life, and neglecting personal hygiene or having unusual thoughts like paranoia or hallucinations. Recognizing these changes in yourself or others, especially when they're prolonged or interfere with daily functioning, signals a need for support.
Psychological symptoms
The first stage of a mental breakdown, often starting subtly, involves feeling overwhelmed, exhausted, and increasingly anxious or irritable, coupled with difficulty concentrating, changes in sleep/appetite, and withdrawing from activities or people that once brought joy, all stemming from intense stress that becomes too much to handle.
