Between 2002 and 2005, E. Richard Brown, PhD, led a team of researchers in fielding a new Housing and Neighborhood Environment module as part of the 2003 California Health Interview Survey (CHIS).
The team surveyed 42,044 people between August 8, 2003, and February 29, 2004, collecting information on their social, physical and housing environments, analyzing their responses, and disseminating the findings.
People all over the country use the CHIS 2003 data set. It is made available to communities in California for their planning and advocacy purposes.
The California Health Interview Survey website includes information about CHIS 2003 questions, methodology, sample design, findings and policy implications.
