Some of the data I use (like geocoded versions of the Panel Study of Income Dynamics or any of the genetic stuff) are obtained under restricted contracts to prevent identifiable information from becoming public, cannot be distributed, and are destroyed after the completion of the project. If you have any questions about these data below or the methodology of any of my publications, please feel free to contact me directly.
