Understanding Literacy and Numeracy
Literacy, numeracy, and technology skills are increasingly important in today's information-rich environments. What people know and what they do with what they know has a major impact on their life chances. For example, people with lower literacy proficiency are more likely than those with better literacy skills to report poor health.
The resources on this page briefly explain literacy and numeracy and how they are measured in national education surveys. You will find a link to adult health literacy data. The page also contains links to resources that discuss literacy policies and practices and ideas about how to promote literacy and numeracy.
What are Adult Literacy and Numeracy?
The U.S. Department of Education defines adult literacy and numeracy in terms of skills that help people accomplish tasks and realize their purposes. Researchers can measure literacy and numeracy skills, but skills are not static. People can build their skills, and even adults with limited skills can get better results when their environments accommodate the skills they have.
- Literacy is understanding, evaluating, using, and engaging with written text to participate in the society, to achieve one's goals and to develop one's knowledge and potential.
- Numeracy is the ability to access, use, interpret, and communicate mathematical information and ideas, to engage in and manage mathematical demands of a range of situations in adult life.

Adult Health Literacy Skills
The U.S. Department of Education collects and reports data adult literacy and numeracy skills. In 2006, they published the only national data on health literacy skills. These studies found that adults who self-report the worst health also have the most limited literacy, numeracy, and health literacy skills.

Youth Literacy Skills
The Department of Education also collects and reports data on school-aged children and youth. Elementary school children with weak literacy and numeracy skills often struggle academically through the middle and high school years. Research shows that academic success, risky behaviors and health status are linked.
Data on Adults' Literacy and Numeracy Skills
The most current adult literacy data come from the Program for the International Assessment of Adult Competencies, a 23 country comparative study. This study assessed adults' proficiency in three domains: literacy, numeracy, and problem-solving in technology-rich environments. Below we present select findings on literacy and numeracy.
In each of these domains, adults perform tasks with different levels of complexity. Their skills with these tasks are quantified and categorized into "proficiency levels." The proficiency level "below level 1" is the lowest level and "level 5" is the highest proficiency level. If they can perform the most complex tasks, they are rated as having proficient skill.
Only 12% of U.S. adults scored in the highest literacy proficiency levels, and only 9% scored in the highest numeracy levels.
