•  employment
•  income
• stressful life events
• depression as measured by the Beck Depression Inventory

The dataset is supplied in Stata format. Be sure to keep a .do file of the syntax you used to answer questions,as you will be asked to upload a pdf version of this syntax to the assignment.

Before answering the questions, it would be wise to explore the dataset a little to be sure you know enough to answer the questions correctly. See also the Data Dictionary.
