Abstract
Previous research in crisis and risk communication has suggested differences across demographic groups in informational needs and response, including the presence of knowledge gaps. In the wake of Hurricane Ike, the current study surveyed 691 Houston area residents to investigate these differences and contrast them with similar data collected following Hurricane Katrina. The results suggest narrowing knowledge gaps, as socioeconomic status
did not predict informational needs or preparations for the storm. Differences in these needs were still detected across sex and ethnicity.
