Mathematical Reasoning

Occupations that rely most on Mathematical Reasoning

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 261 occupations where this is important.

How AI is used by roles that need Mathematical Reasoning

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). 70.9% of the 261 roles where this is important carry observed AI-usage data (185 roles).

Across those roles, 49.5% of AI conversations are people working with AI and 31.3% hand a task to AI , with an average autonomy of 3.64 / 5.

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 Mathematical Reasoning matters most across the economy. Employment reach is the share of an industry's workers in occupations that significantly rely on Mathematical Reasoning (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 16.0% of workers are in occupations that significantly rely on Mathematical Reasoning (measured across 67 industries).

Sectors with the most such workers

Industries where it is most concentrated

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.

Related abilities, skills & knowledge

Capabilities required by many of the same occupations — a measure of which skills, knowledge and abilities tend to travel together, not a judgment of similarity.
