CASPER is a validated two-stage cluster sampling methodology developed by the Centers for Disease Control and Prevention (CDC) to rapidly obtain information about the health and resource needs of a community.1 Information obtained is generalizable to the entire sampling frame, providing population-based estimates. This methodology is designed to be inexpensive, quick, and scalable, making it ideal for use in disaster settings. CASPERs can also be used to establish baseline preparedness levels and build capacity to  \n3  \nconduct post-disaster CASPERs. This was the first CASPER needs assessment survey conducted on Hawaiʻi Island with support provided by the Kauaʻi District Health Office, which has conducted CASPERs annually from 2017-2024 (excluding 2021) . Through these efforts, 37 new HDOH staff and community volunteers were trained in this rapid health needs assessment methodology.  \nObjectives  \nDeveloped in consultation with county emergency preparedness stakeholders during the survey concept and development phrase, the 2025 East Hawaiʻi Island CASPER included an assessment of:  \n1. Emergency and evacuation plans  \n2. Emergency supplies  \n3. Infectious disease awareness and concerns  \n4. General life on Hawaiʻi Island  \nIntroduction  \nMETHODS  \n2 0 2 5 Hawai ʻ i Island CASPER Sampling  \nCASPER is a two-stage cluster sampling methodology. The first stage, cluster selection, begins with the determination of a sampling frame, or the area from which the sample is selected and to which the data is generalized. Once the sampling frame is determined, thirty census blocks (termed “clusters”) are randomly selected. The probability of a census block being selected is proportional to the number of housing units located within it.  \nThe second stage of sampling, household selection, is typically completed by survey teams in the field. This stage involves systematic selection of seven households per cluster. Homes are selected by dividing the total number of housing units in each cluster by seven to determine a sequence number (“n”) . Survey teams then attempt to interview every“nth” house, with an ultimate target of 210 surveys.  \nFigure 1. Satellite imagery of all census blocks eligible for selection in the sampling frame for the East Hawaiʻi Island CASPER.  \n4  \nCluster and Household Selection  \nThe sampling frame for this assessment consisted of occupied housing units on the Eastern half of Hawaiʻi Island (Figure 1) . The Eastern half of Hawaiʻi Island was prioritized for the survey due to increased vulnerability to various natural disaster hazards. The 2020 census block data was used to select 30 clusters via random number generation.2 The Eastern half of Hawaiʻi Island has a total of 2,742 cens","cbCailhjmMu26PEB","https://ap.wps.com/l/cbCailhjmMu26PEB","pdf",18360517,39,"English","# Introduction\n## Background\n## Objectives\n# Methods\n## 2025 Hawaiʻi Island CASPER Sampling\n## Cluster and Household Selection","[{\"question\":\"What is the CASPER methodology used in this report?\",\"answer\":\"CASPER is a validated two-stage cluster sampling methodology used to rapidly obtain information about a community’s health and resource needs.
