There are five ways to select variables to add to your "shopping cart" within
the Data Center: Search, Cross-Year Index, File, Variable List and Previous Carts.
You can use any of the five methods, and you can switch methods while you "shop."
To view the variables you have selected, simply click on the shopping cart on the right.
While the “Cross-year index” and “File” options cover nearly all variables included in the PSID,
the “Search” and “Variable List” options capture all PSID variable.
Very few historical variables that had been collected or generated in special projects and for only
selected years are available as Auxiliary Files.
