## Content

**Source:** "Mental Health Workforce Inequities Across Income Levels: Aligning Global Health Indicators, Policy Readiness, and Disease Burden" — published PMC 2025 / Dove Medical Press (Psychology Research and Behavior Management).

**Core finding:** Mental health workforce density and disease burden are inversely correlated — the countries with the highest burden have the fewest workers.

### Psychiatrist density by income level
- **Low-income countries:** 0.1 psychiatrists per 100,000 people
- **Lower-middle-income countries:** 0.4 psychiatrists per 100,000 people
- **Upper-middle-income countries:** 1.7 psychiatrists per 100,000 people
- **High-income countries:** 8.6 psychiatrists per 100,000 people

**Implied ratio: 86x disparity** between high- and low-income countries. A person in a high-income country has 86 times greater access to a psychiatrist per capita than a person in a low-income country.

### Overall workforce
- Global median: 13.5 specialized mental health workers per 100,000 population
- Range: 1.1–2.4 in low/lower-middle-income countries → 67.2 in high-income countries

### Disease burden inversion
Lower-middle-income countries have the **highest number of suicide deaths globally** — 293,076 in 2021 — yet have only 0.4 psychiatrists and 1.3 nurses per 100,000.

The highest disability-adjusted life years (DALYs) from depression, bipolar disorder, and suicide are concentrated in low- and lower-middle-income countries — which also have the lowest mental health workforce density.

### Economic correlation
Strong positive correlation between GDP per capita and psychiatrist prevalence (r = 0.77, p < .001). Mental health workforce is not a standalone workforce policy problem — it reflects the general relationship between economic development and health infrastructure.

## Agent Notes
**Why this matters:** This paper provides the international workforce data that grounds the KB's mental health supply gap claim in global reality. The 86x psychiatrist density disparity is the most striking number — it's not a gap, it's a chasm. More importantly, the disease burden is inverse: the countries with the highest suicide rates and depression DALYs have the fewest mental health workers. This is Belief 2 (social and structural determinants dominate) and Belief 3 (structural misalignment) operating at the civilizational scale.

**What surprised me:** The **lower-middle-income country suicide concentration** — 293,076 deaths in 2021, the highest of any income tier, with only 0.4 psychiatrists and 1.3 nurses per 100K. This means the world's highest mental health disease burden falls on countries that are almost completely unable to provide clinical care. And Belief 2 applies here too — the vast majority of mental health determinants in these countries are non-clinical (poverty, conflict, social fragmentation). Clinical workforce deficits matter, but they're not the primary explanation for the burden.

**What I expected but didn't find:** Country-specific data on mental health treatment investment relative to disease burden. The income-level grouping is the right frame, but country-level variance within income groups would be more actionable for policy.

**KB connections:**
- Extends [[the mental health supply gap is widening not closing because demand outpaces workforce growth and technology primarily serves the already-served rather than expanding access]] from US-specific to global
- Supports Belief 1 (healthspan as binding constraint): 293,076 suicide deaths in lower-middle-income countries annually = one of the clearest civilizational failure signals
- The r=0.77 correlation between GDP and psychiatrist density means mental health workforce is a downstream consequence of economic development — which means improving mental health in low-income countries requires more than workforce training programs

**Extraction hints:**
- Primary claim: "Mental health workforce density is inversely correlated with mental health disease burden globally — countries with the highest suicide rates and depression DALYs have 86x fewer psychiatrists per capita than high-income nations, and this disparity is structurally determined by GDP (r=0.77)"
- This is a confirmed international claim that extends existing KB arguments

**Context:** Published 2025. Part of a literature examining global mental health system disparities. Dove Medical Press / PMC. The data aligns with WHO Mental Health Atlas 2024 (same period, complementary methodology).

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: [[the mental health supply gap is widening not closing because demand outpaces workforce growth and technology primarily serves the already-served rather than expanding access]]
WHY ARCHIVED: Fills the KB's international gap — the mental health supply claim is US-only. This paper provides the global picture with a stark inversion: burden concentrated where workforce is thinnest. The 86x disparity and the r=0.77 GDP correlation are the most extractable facts.
EXTRACTION HINT: The claim should be framed as a structural finding about inverse burden-workforce correlation, not just a workforce shortage claim. The GDP correlation is important — it means the solution is not just "train more psychiatrists in LMICs" but requires addressing the economic development gradient that drives the workforce disparity.
