Description of the data and file structure

Only US adults who age 18 and older were recruited as participants. First, quotas for gender, age, race/ethnicity, region, and political orientation were be utilized to ensure a diverse US sample that have characteristics similar to US census data. Then, only participants from the 12 western states (i.e., fire-prone regions) were included as participants. Such states include: Alaska, Arizona, California, Hawaii, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming. Researchers hired Qualtrics, a survey company, for the data collection, and the screening were conducted by Qualtrics project manager.

Before data collection, we conducted a power analysis with 5% margin of error, 95% confidence level and 332,403,650 (2022 US population) as population size. We also considered the number of variables. We have more than 10 variables and need relatively big sample size to allow enough variation and valid comparisons across different groups of participants with different demographic characteristics, such as gender, income, education, wildfire knowledge levels, etc.

Qualtrics survey manager used screening question “which state are you currently located at” and IP address to verify and make sure participants recruited for this study are residents among the 12 western US states.
