* Job Level: Entry-level positions might require basic literacy and numeracy, while higher-level jobs demand advanced skills in all three areas.
* Industry: A construction worker might need basic math for measurements, while a software engineer needs advanced math, reading, and writing skills for coding and documentation.
* Specific Role: Even within the same industry, the skills needed can differ greatly. A marketing manager requires strong writing and reading skills, while a marketing analyst needs strong math and data analysis skills.
While nearly all jobs require *some* level of reading and likely some level of math (even if just basic counting), the *degree* to which these skills are needed is the key variable. Therefore, a percentage would be highly speculative and misleading. It's safe to say that the vast majority of jobs, at least to some minimal degree, utilize reading, writing, and math skills.
