Panel Data


Panel data refer to longitudinal data sets generated by observing a sample of
individuals over time. Therefore, a panel has two dimensions involving
individuals and time. Panels are a mix of cross sectional information and time
series information.


Examples:

1. The National Longitudinal Survey of Labor Market Experience follows groups
of individuals that participate in the labor force, through regular annual
interviews.

2. The Panel Study of Income Dynamics (PSID) collects annual economic
information on a national sample of about 6,000 families and 15,000
individuals since 1968.
