From a recent F&S article. The entire piece is well worth reading.

Hunting's vital signs continue the steady decline that began in the 1970s, according to a wave of research released this year. A new U.S. Fish and Wildlife Service survey shows that our total numbers are down: just 12.5 million, dropping half a million in the last five years alone. Our average age is up: 24 percent of us are over 55, whereas only 12 percent of us are under 25. Recruitment is failing: 38 percent fewer newcomers joined our ranks in the last 15 years. And the proportion of Americans who hunt has dropped to 3 percent, a figure guaranteed to shrink as the general population continues to expand.
The decline persists despite an ever expanding menu of private and government programs designed to spur interest in the sport. States and industry groups rightfully trumpet their occasional successes, yet a few strokes on a calculator bring reality crashing back: If the sport continues to shed about 100,000 members a year, there will be very few of us left by 2050.
