2010 Participation of 6- to 15-Year-Olds:
Data From Screening Interviews
The 2011 National Survey of Fishing,
Hunting, and Wildlife-Associated
Recreation was carried out in two
phases. The first (or screening) phase
began in April 2011. The main purpose
of this phase was to collect information
about all persons 16 years old and
older in order to develop a sample of
potential sportspersons and wildlife
watchers for the second (or detailed)
phase. However, information was also
collected on the number of persons
6 to 15 years old who participated in
wildlife-related recreation activities in
2010.
It is important to emphasize that the
information reported from the 2011
screen relates to activity only up to and
including 2010. Also, these data are
reported by one household respondent
speaking for all household members
rather than the actual participants.
In addition, these data are based on
long-term recall (at least a 12-month
recall), which has been found in Survey
research (see Investigation of Possible
Recall/Reference Period Bias in
National Surveys of Fishing, Hunting
and Wildlife-Associated Recreation,
December 1989, Westat, Inc.) to add
bias to the resulting estimates. In many
cases, longer recall periods result in
overestimating participation and expenditures
for wildlife-related recreation.
Tables B-1 through B-4 report data on
6- to 15-year-old participants in 2010.
Detailed expenditures and recreational
activity data were not gathered for the
6- to 15-year-old participants.
Because of differences in methodologies
of the screening and the
detailed phases of the 2011 Survey,
the estimates of the two phases are
not comparable. Only participants 16
years old and older were eligible for
the detailed phase. The screening phase
covered activity for 2010 or earlier; the
detailed phase has estimates for only
2011. The detailed phase was a series
of interviews of the actual participants
conducted at 4- and 8-month intervals.
The screening phase was a single interview
of one household respondent who
reported household events with one
year or more recall. The shorter recall
period of the detailed phase enabled
better data accuracy.
