From the Census Bureau:
The Census Bureau recognizes that users of ACS data have varied backgrounds, educations, and experiences. They need different kinds of explanations and guidance to understand ACS data products. To address this diversity, the Census Bureau worked closely with a group of experts to develop a series of handbooks, each of which is designed to instruct and provide guidance to a particular audience. The audiences that we have chosen are not expected to cover every type of data users, but they cover major stakeholder groups familiar to the Census Bureau.
The handbook series is called A Compass for Understanding and Using American Community Survey Data. The specific handbooks are listed below, along with a brief summary of each of the target audiences.
The U.S. Census Bureau recently released two new ACS Compass Products handbooks...
What Users of Data for Rural Areas Need to Know introduces the ACS to people who care about, and use, social, demographic, economic, and housing data for small governmental units and rural communities. Using the devise of a single case study, this handbook illustrates a variety of aspects of the ACS and shows how results from the ACS are both similar to, and different from, data formerly gathered in conjunction with the decennial census.
What Users of Data for American Indians and Alaska Natives Need to Know provides an overview of the ACS data produced for the American Indian and Alaska Native populations. It describes the data products, provides information about how to access and use these products, and includes case studies to illustrate how best to use these data. Input from the Census Advisory Committee on the American Indian and Alaska Native Population and other stakeholders suggested the need for these ACS education materials.
