Written Expression
Ability · O*NET work requirement
The ability to communicate information and ideas in writing so others will understand.
In the O*NET occupational database, Written Expression is an ability that work requires. O*NET rates how important it is (1–5) and what level of it a job needs (0–7) for every U.S. occupation. It is rated as important (3 or higher) in 633 of 894 occupations.
Breadth here means how widely O*NET rates this ability as important across occupations — not that it is rare, high-paying, or currently in employer demand.
Occupations that rely most on Written Expression
Ranked by O*NET importance to the occupation (1–5). Bars are sized against the 1–5 scale; the level column is what depth of the ability the job needs (0–7).
Showing the top 40 of 633 occupations where this is important.
How AI is used by roles that need Written Expression
This ability is not itself "being automated" — but we can look at the roles for which O*NET rates it important and ask how those people actually use AI. This rolls the Anthropic Economic Index per-role signal up across those roles (importance-weighted). 65.1% of the 633 roles where this is important carry observed AI-usage data (412 roles).
Across those roles, 48.8% of AI conversations are people working with AI and 31.8% hand a task to AI , with an average autonomy of 3.60 / 5.
| Collaboration pattern | Share | What it means |
|---|---|---|
| directive | 29.8% | AI does it; you give the instruction |
| task iteration | 25.8% | you and AI go back and forth |
| learning | 19.8% | you ask AI to explain or teach |
| validation | 3.3% | you do it; AI checks your work |
| feedback loop | 2.0% | AI does it, then adjusts from your feedback |
Roles behind this signal
The roles where this ability is most important and that also have the most AEI data. "Works with AI" is the role's share of conversations that augment rather than automate.

Source: Anthropic Economic Index (2026-01-15-v4-plus-2025-03-27-v2) over a sample of Claude.ai Free and Pro conversations — not all AI tools and not the whole workforce. Shares are of observed conversations, weighted by how important this ability is to each role; some conversations are left unclassified by Anthropic's taxonomy, so shares need not sum to 100.
Industries that concentrate this
Where Written Expression matters most across the economy. Employment reach is the share of an industry's workers in occupations that significantly rely on Written Expression (O*NET importance ≥ 3 of 5). Concentration compares that reach to the national average industry, so a value above 1× means the requirement is more pervasive here than across the economy as a whole.
Nationally, about 57.3% of workers are in occupations that significantly rely on Written Expression (measured across 67 industries).

Reach is a measure of how widespread a requirement is across an industry's workforce, not how intensively any individual uses it. Sector worker counts come from BLS OEWS employment; the significance threshold and tool use come from O*NET. Industries shown by concentration are filtered to a real worker base so a tiny specialty cannot top the list on rounding.
