Appendix B.2010 Participation <strong>of</strong> 6- to 15-Year-Olds <strong>and</strong>Historical Participation <strong>of</strong> Sportspersons:Data From Screening InterviewsThe 2011 <strong>National</strong> <strong>Survey</strong> <strong>of</strong> <strong>Fishing</strong>,<strong>Hunting</strong>, <strong>and</strong> <strong>Wildlife</strong>-AssociatedRecreation was carried out in twophases. The first (or screening) phasebegan in April 2011. The main purpose<strong>of</strong> this phase was to collect informationabout all persons 16 years old <strong>and</strong>older in order to develop a sample <strong>of</strong>potential sportspersons <strong>and</strong> wildlifewatchers for the second (or detailed)phase. However, information was alsocollected on the number <strong>of</strong> persons6 to 15 years old who participated inwildlife-related recreation activities in2010.It is important to emphasize that theinformation reported from the 2011screen relates to activity only up to <strong>and</strong>including 2010. Also, these data arereported by one household respondentspeaking for all household membersrather than the actual participants.In addition, these data are based onlong-term recall (at least a 12-monthrecall), which has been found in <strong>Survey</strong>research (see Investigation <strong>of</strong> PossibleRecall/Reference Period Bias in<strong>National</strong> <strong>Survey</strong>s <strong>of</strong> <strong>Fishing</strong>, <strong>Hunting</strong><strong>and</strong> <strong>Wildlife</strong>-Associated Recreation,December 1989, Westat, Inc.) to addbias to the resulting estimates. In manycases, longer recall periods result inoverestimating participation <strong>and</strong> expendituresfor wildlife-related recreation.Tables B-1 through B-4 report data onfirst-time participation <strong>and</strong> the mostrecent year <strong>of</strong> hunting <strong>and</strong> fishingfor participants 6 years <strong>of</strong> age <strong>and</strong>older. Tables B-5 through B-8 reportdata specifically on 6- to 15-year-oldparticipants in 2010. Detailed expenditures<strong>and</strong> recreational activity data werenot gathered for the 6- to 15-year-oldparticipants. Table B-9 lists the trenddata for 6- to 15-year-old participants.Because <strong>of</strong> differences in methodologies<strong>of</strong> the screening <strong>and</strong> thedetailed phases <strong>of</strong> the 2011 <strong>Survey</strong>,the estimates <strong>of</strong> the two phases arenot comparable. Only participants 16years old <strong>and</strong> older were eligible forthe detailed phase. The screening phasecovered activity for 2010 or earlier; thedetailed phase has estimates for only2011. The detailed phase was a series<strong>of</strong> interviews <strong>of</strong> the actual participantsconducted at 4- <strong>and</strong> 8-month intervals.The screening phase was a single interview<strong>of</strong> one household respondent whoreported household events with oneyear or more recall. The shorter recallperiod <strong>of</strong> the detailed phase enabledbetter data accuracy.100 2011 <strong>National</strong> <strong>Survey</strong> <strong>of</strong> <strong>Fishing</strong>, <strong>Hunting</strong>, <strong>and</strong> <strong>Wildlife</strong>-Associated Recreation U.S. Fish <strong>and</strong> <strong>Wildlife</strong> Service <strong>and</strong> U.S. Census Bureau
