The American Community Survey covers a large number of social and economic topics--too many to present at once. We will introduce many in this course, but you should also know where to find table and variable names. If you append /groups.html to the base URL for any Census data product, you will see a list of detailed tables available for that product.
You should be able to construct the base URL for the ACS 2017 1-year sample. Append /groups.html and go to that URL in your browser. Now use your browser's "Find in Page" feature to find the table title "MOVERS BETWEEN REGIONS IN THE UNITED STATES". What is the table name?
