This year marks the 100th anniversary of the National Park Service, a system signed in to law by President Woodrow Wilson and frequently hailed as “America’s best idea.” Most Americans have a favorable opinion of the agency and are fine with the number of national parks in the country.

A new Rasmussen Reports national telephone and online survey of 1,000 American adults finds 74 percent of American Adults view the Park Service favorably, including 35 percent who have a Very Favorable opinion of it. Just 13 percent regard the NPS somewhat or Very Unfavorably. Another 13 percent are undecided. 

Only 5 percent believe there are too many national parks in the United States, while 34 percent say there are not enough. Most (52 percent) think the number of U.S. national parks is about right.

Among Americans with a Very Favorable opinion of the National Park Service, 47 percent say there are not enough parks, but nearly as many (45 percent) say the number is about right.
