The Research Director, Jon Stiles has overall responsibility for the research activities of the CCRDC. He works extensively with researchers who use the CCRDC and promotes the Center to researchers throughout California and the nation. While his appointment is at UC Berkeley, he is equally responsible for the research activities at all of the CCRDC’s sites.

Each laboratory employs an RDC administrator who is a US Census Bureau employee. The RDC Administrators are responsible for administering the laboratories, assisting researchers with proposal development and project execution, and safeguarding data confidentiality. They act as liaisons between the researchers and data experts at CES or other parts of the Census Bureau and they ensure that knowledge gained from the research at the RDC is made available to the Census Bureau for use in improving Census Bureau programs. They are typically the first point of contact for researchers who use the center.

Howe, Huskey, Berman (2013) "Migration in Arctic Alaska: Empirical evidence of the stepping stones hypothesis." Migration Studies
doi: 10.1093/migration/mnt017

This article tests for hierarchical migration patterns using data from the Alaskan Arctic. We focus on migration of Iñupiat people, who are indigenous to the region, and explore the role of income and subsistence harvests in the migration choice. Evaluating confidential microdata from the US Census Bureau’s 2000 Decennial Census of Population and Income with a mixed multinomial and conditional logit model we find evidence of step-wise migration up and down an urban and rural hierarchy, results that are consistent with Ravenstein’s (1885) early hypothesis of step-wise migration. We also find that where migrants choose to move is a function of place, personal, and household characteristics.
