I Ran the Numbers on 207,919 People Across 22 Countries

The Mental Health Industry Isn’t Ready for What I Found. Note: This article was written with the assistance of Claude AI.

Harvard, Baylor, and Gallup quietly released the most comprehensive study on human flourishing ever conducted. 207,919 people, 22 countries, 232 variables. Two years of longitudinal data tracking everything from depression and anxiety to inner peace, loneliness, bodily pain, and purpose.

It’s called the Global Flourishing Study, and the Wave 2 dataset went public on the Open Science Framework in April 2026 with no restrictions on non-sensitive use.

I downloaded it. I went through it. And the story the data tells is not the one the healthcare industry talk about.

The stat that stopped me cold:

Of the people who reported frequent depression in Year 1 of the study, 48.1% were still depressed in Year 2. For anxiety, 49.6%. For loneliness, 44.9%.

For chronic bodily pain? 67.7% were still in pain a full year later.

Let that land. Across 22 countries, across every income level, every healthcare system, every cultural context, nearly half the people who struggled stayed struggling. For pain, it was two-thirds.

That’s a market failure.

We’re talking about the fundamental inadequacy of the current intervention model. Pills, therapy, wait lists, referrals, repeat.

The second thing the data reveals is that depression, anxiety, pain, loneliness, and low mental health compound.

Depression and anxiety correlate at r = 0.62 in this dataset. One in three adults globally carries two or more of these burdens simultaneously. They’re not four separate conditions requiring four separate prescriptions. They’re one dysregulated nervous system expressing itself across multiple channels.

This is the insight the current model struggles with. You can’t solve a systems problem with point solutions. You can’t prescribe your way out of a nervous system that’s stuck in a chronic stress response when the prescription only addresses one symptom at a time.

The youth crisis is accelerating

If the persistence numbers are alarming, the generational skew is worse.

45% of adults aged 18 to 29 in this dataset carry multiple simultaneous mental health burdens. For adults over 60, it’s 21%.

Read that. The youngest adults in the study are more than twice as burdened as the oldest. This is problem that’s compounding generationally.

It’s compounding into a demographic that is the most digitally connected, the most health-aware, and the most disillusioned with traditional healthcare delivery in history. They’re going to look for something that works differently.

What works differently?

I’m not a clinician. But I can read a dataset, and what this data screams is that the next generation of mental health intervention needs to address the nervous system as a system, not as a collection of isolated symptoms.

That means modalities that work across depression, anxiety, pain, and dysregulation simultaneously. Approaches that don’t require a prescription pad and a 90-day titration cycle. Technologies that meet people where the burden actually lives, which, according to 207,919 people across 22 countries, is in the body as much as the mind.

Electroceuticals. Neuromodulation. Vagus nerve stimulation. Bioelectronic medicine. They’re the logical conclusion of the data.

When two-thirds of chronic pain sufferers are still suffering a year later under the current model, and when that pain clusters with depression and anxiety at rates the data makes impossible to ignore, the question is how fast alternative modalities will find a market.

What this means for investors

The Global Flourishing Study is the product of Harvard’s Human Flourishing Program, Baylor’s Institute for Studies of Religion, Gallup, and the Center for Open Science. It’s produced over 100 peer-reviewed publications and a dedicated collection in the Nature Portfolio.

This is the gold standard of global wellbeing research, and it’s sitting on the Open Science Framework right now, free for anyone to download.

If you’re allocating capital into health, wellness, or mental health, and you haven’t looked at this dataset yet, you’re working with an incomplete map. The TAM story alone, with a multi-burdened youth population that’s growing rather than shrinking, should change how you evaluate every pitch deck that lands on your desk.

The pharma model solved the acute crisis. It hasn’t solved the chronic one. The persistence numbers prove it. And the generation inheriting the problem has zero patience for more of the same.

The data is free. The insight is expensive.

I set out to understand what 207,919 people across the planet are actually experiencing, year over year, measured by the most rigorous methodology available.

What I found is a world where the mental health crisis is a crisis of persistence. People get stuck. The current model doesn’t unstick them. It’s getting worse with every generation that enters adulthood.

The dataset is at osf.io. Go look for yourself.

And if you’re building something that addresses the nervous system as a whole, rather than one symptom at a time, the evidence base you’ve been waiting for is already here. Harvard built it for you.
