and its descriptions of methods for computing approximate estimates of sampling errors for estimates for which sampling errors are not published. Steps should be identified to improve the usability and ease of comprehension of information on sampling errors.

Recommendation 7-7: The Census Bureau should develop and publish an ongoing quality profile for the ACS to inform users of the survey’s data quality, to guide the development of a continuing program of data quality assessments, and to identify areas for survey improvement. The Census Bureau should seek input from users on priority topics for assessment and design reports that they would find to be useful additions to the technical reports.

Recommendation 7-8: The Census Bureau should continue to seek funding with which to implement methods panels (large samples of households) for experimentation with questionnaire design, question wording, residence rules, data collection mode, and other features of the ACS. The methods panels should be conducted annually so that the survey can be kept current in meeting data needs and collecting responses in the most efficient and effective ways.
