The report serves as the baseline for examining how Americans are spending their time and money outdoors.
According to the survey, 87.5 million U.S. residents 16 years and older participated in wildlife-related recreation, a 6-percent increase from the last survey in 2001. However, the number of hunters and anglers fell from 37.8 million in 2001 to 33.9 million in 2006. The most recent survey also showed an 8-percent increase in the number of wildlife-watchers since 2001, but reported little change in total expenditures for that activity.
The survey has been conducted every five years since 1955.
