Since 2013, the Programme for the International Assessment of Adult Competencies (PIAAC) has published a large volume of official statistics about the proficiency of adults in the United States.
The published statistics are mainly for the nation and for major subgroups. However, policymakers, business leaders, and educators/researchers often need information about adults’ skills and knowledge in smaller geographic areas, such as states or counties.
To address this need, PIAAC will use advanced statistical modeling approaches to produce literacy and numeracy estimates for all states and counties in the United States. A visualization-based website will be launched in spring 2020 that will allow users to access small-area estimates through heat maps and summary card displays. This user-friendly website will provide precision estimates and facilitate statistical comparisons among counties and states.
