Our target population for the research is all public health and emergency management-related organizations in Alberta. The construction of the project's sampling frame is based on a stratified, multistage cluster design. The strata are four administrative divisions: (1) provinciallevel agencies, (2) sub-provincial administrative agencies, i.e., emergency-management districts (disaster services) and regional health authorities, (3) metropolitan areas, and (4) towns and local areas. Within strata 1-3, the sampling frame includes all public health or emergency management organizations, i.e., agencies, departments, or units, within those strata. The fourth stratum will be substratified according to the Alberta Emergency Management district divisions into 6 geographical areas: (1) northwestern Alberta, (2) northeastern Alberta, (3) northcentral Alberta, (4) central Alberta, (5) south-central Alberta, and (6) southern Alberta. From each of the 6 geographical regions, we will draw a proportionate, random sub-sample of towns. For stratum 4, the sampling frame consists of all public health or emergency managementrelated organizations in those towns randomly selected. The project's frame population will thus consist of those organizations listed in the strata 1-3 sampling frame and those listed in the stratum 4 sampling frame.
