This report makes recommendations that address some immediate needs in light of the data release schedule, which calls for the publication of the first set of 5-year period estimates before the end of 2010, and publication of updated estimates every year thereafter. While the panel’s initial deliberations and recommendations cannot affect the estimates in this first release of 5-year data, the intent is to use an evaluation of the initial release to potentially improve the ACS estimates planned for release in late 2011. Specifically, this report focuses on statistical methodology and proposes short-term revisions as well as research needed to inform longer term methodological decisions. Chapter 2 discusses the ACS sampling frame development and scope of coverage for the GQ component of the sample. Chapter 3 focuses on sample selection and allocation, and Chapter 4 discusses weighting and estimation procedures. The final chapter outlines the panel’s plans for the remainder of the study and proposed areas of inquiry for the final report.
