Trend of Population and Sport Fishermen and Hunters 



The trends of the population and of the number of sport 

 fishermen and hunters, 1955 through 1975, are shown in the 

 illustration on page 23. Total United States population trend 

 data were furnished by the Bureau of the Census. 



The trend in number of sport fishermen and hunters was 

 constructed from statistics obtained from a simple correlation of 

 (1) the number of fishermen and hunters and (2) per capita 

 disposable personal income after taxes — both series for the period 

 1947-1960. 



These projections measure the future only by the .present 

 trends of the population, numbers of sportsmen, and personal 

 income. 



Sport Fishing and Hunting Trips 



Transportation for sport fishing and hunting trips includes all 

 types — from walking to air travel. The automobile accounted 



for the major portion of the trips and distance traveled. Illus- 

 trations showing summary data on trips and automobile passen- 

 ger mileage are on pages 4 and 5, and total automobile travel 

 on pages 31-33. Additional data on trips are shown on pages 57 

 and 58. 



Distance traveled is the total number of miles traveled using 

 all types of transportation on trips taken primarily for sport fish- 

 ing and hunting. 



Car miles are the miles traveled by automobile primarily for 

 sport fishing and hunting. Passenger miles are the number of 

 miles traveled by sport fishermen and hunters in automobiles 

 on trips taken primarily for fishing and hunting. For example, 

 if three fishermen traveled 100 miles on a fishing trip, the car miles 

 would be 100 and the passenger miles would be 300. 



Recreation Day 



A recreation day is a day, any part of which was spent fish- 

 ing or hunting. 



Sport Fishing and Hunting Licenses 



Most sportsmen who fish or hunt are required to buy li- 

 censes and to pay specific fees to the State or Federal govern- 

 ments. Since 1955 the number exempted from paying for such 

 purchases has been reduced considerably. Sportsmen who are 

 exempted in some States from paying some kind of fee include: 

 (1) those under a specified age; (2) those over a specified age; 

 (3) the disabled; (4) active servicemen; (5) property owners; 

 and, (6) aborigines and indigents. Licenses are required for 

 fishing in salt water in only two States. The reduction in the 

 number of sportsmen exempted from paying for a license or fee 

 is clearly shown in the case of those under 16 years of age
