NFPA’s Survey and How It Relates to NFIRS Marty Ahrens NFIC December 2007 To Be Covered What is NFPA’s survey? What does it do that NFIRS doesn’t? What does NFIRS do that the survey doesn’t? How are national estimates calculated for specific fire problems? Upcoming changes to the survey Common questions A bit about NFPA statistics What is the NFPA Survey? Based on a statistical sample All local departments protecting populations of at least 50,000 Random sample, stratified by population, of small and medium communities Collects fire department experience data for past year Summary data only Survey Contents Fire department characteristics Responses by broad incident type Greater detail on false alarms Fires, civilian deaths and injuries, direct property damage by broad incident type Structure fires by broad property type Firefighter injuries by duty Firefighter fireground injuries by cause Fire department vehicle accidents Major fires What Does the Survey Do that NFIRS Doesn’t? Projections are possible because of the statistical sample Same rules throughout the country In NFIRS, different states have different reporting requirements Previous year’s analysis is complete by late summer or early fall What Does NFIRS Do that the Survey Doesn’t? Lots! More detail Incident based system can answer more questions Can compare different jurisdictions if they follow the same reporting policies and practices How a Fire Gets Counted Fire dept. called Report done Report to state Released or sent to USFA - In NFIRS Report not Not sent to Not sent to USFA done state or server Not in NFIRS Handled privately Not included in statistics Not included in statistics Not included in NFIRS -May be captured by NFPA survey What Do the Survey and NFIRS Have in Common? Both use NFIRS codes Fire departments fill out both Data quality can be an issue NFPA follows up on vehicle fire deaths How Are National Estimates Calculated? NFIRS provides the details, but not the whole universe of reported fires NFPA survey is sample-based, so projections can be made about total Lacks detail Combine the two to develop scaling ratios National Estimates Calculations Projected totals from NFPA survey NFIRS totals Different scaling ratios for Residential structures, non-residential structures, vehicles, and outside and other Fires, deaths, injuries, and property damage Upcoming Changes to Survey CPSC wanted survey information on confined fires 2007 survey asks about the number of Confined and non-confined Residential and all structure fires Mutual aid is restricted to mutual aid given Some departments will not be able to answer these questions the first year Common Questions about the Survey Why didn’t we get one this year? Random sample for smaller departments Can only accept surveys from departments in the sample Sample varies by year Department is likely to be in sample in some future years Can I get a copy of the survey? Blank copies Yes For your own fire department Yes, if we have it For other fire departments No Can I get fire statistics by state? For unintentional injury fire deaths Yes Death certificate data used, not NFPA survey For fires No Inconsistent reporting practices NFPA survey is a national sample Is an incident counted twice if it is in NFIRS and the survey? No Survey projections are calculated independently of NFIRS If all incidents captured in the survey were in NFIRS, the scaling ratio should be 1 What happens when a major fire is in the survey but not NFIRS? Incident will usually be included in the general scaling ratios September 11 and some wildland fires were not Details of fire will not be in NFIRS Station Nightclub fire increased the non-residential fire death ratio Why don’t you adjust estimates when you know about a fire not in NFIRS? National estimates are projections Inclusion or exclusion of serious fires will make big difference when scaled up We footnote rather than adjust Adjustments will always be incomplete NFPA Statistics CD of our reports in packet Also brief statistical fact sheets Sign up for quarterly CDs and/or e- mailed reports Reports are copyrighted Links are welcome We will send reports to fire service for free More on NFPA Statistics NFIRS used in almost all Thank you for making it possible With lead time, we can do custom work Fee may be waived if it contributes to NFPA’s mission Help us get the statistics to people who provide the data In Summary NFPA survey and NFIRS are complementary Both are used for national estimates Thank you for helping us understand the fire problem
