SampleNon-probability combining aspects of purposive and quota • Quota Sampling • “Hard” rules governing representation of variables & variable levels in chosen sample; • Ensures desired diversity. • Analogous to stratified sampling methods; • Purposive Sampling: dependent on “expert” judgment.
SampleCriteria for Selecting from NEMIS • Received awards listed in NEMIS whose objective was to mitigate damage from earthquakes, flood, and/or wind; • At high or medium risk of earthquakes, flood, and/or wind; • Single jurisdiction within a state with the legal title: city, town, borough, village or county; • Both project and process (includes Project Impact) activities were funded; • Received project and process awards totaling $500,000; • Received a total of 15 awards; • At least one mitigation award has been completed/closed; • Population of at least 10,000.
SampleApplying Criteria to NEMIS • Step 1—All grants in NEMIS data set of 8/6/03, (N=8,030). • Step 2—Valid perils: earthquake, wind, flood (n=7,047). • Step 3—Valid project status: approved, awarded, closed, completed (n=7,047). • Step 4—Eliminate territories (n=6,833). • Step 5—Eliminate invalid communities: statewide entities, special districts, non-profits (n=5,267). • Step 6—Rename like subgrantees (n=5,267). • Step 7—Aggregate on subgrant (n=2,660). • Step 8—Flag Project Impact Communities in NEMIS (n=2,660; Project Impact: n=102). • Step 9—Apply eligibility criteria (n=113).
SampleCriteria Used to Select from the 113 communities • The combination of hazards for which communities had received FEMA awards; • Available hazard maps identified community at “high risk” of at least one hazard; • Community identified as small (10,000-49,999), medium (50,000-499,999), or large (500,000); and • FEMA region.
Distribution of Communities by FEMA Awards and Quota Limits Set (N = 113)
Distribution of Communities and Quota Limits Set for Being at High Risk of Earthquake, Flood or Wind Hazard (N = 113)1 1Adds to more than 113 because some some communities are at high risk of two or three hazards.
