A newspaper's circulation is the number of copies it distributes on an average day. Circulation is one of the principal factors used to set advertising rates. Circulation is not always the same as copies sold, often called paid circulation, since some newspapers are distributed without cost to the reader. Readership figures are usually higher than circulation figures because of the assumption that a typical copy of the newspaper is read by more than one person.
In many countries, circulations are audited by independent bodies such as the Audit Bureau of Circulations to assure advertisers that a given newspaper does indeed reach the number of people claimed by the publisher. There are international open access directories such as Mondo Times, but these generally rely on numbers reported by newspapers themselves.
In many developed countries, newspaper circulation is falling due to social and technological changes such as the availability of news on the internet. On the other hand, in some developing countries circulation is increasing as these factors are more than cancelled out by rising incomes, population, and literacy.

The heyday of the newspaper industry was the 1940s, but the percentage of Americans reading newspapers began to decline with the increased competition from radio, television and, more recently, the Internet. A growing population helped the absolute circulation numbers continue to increase until the 1970s, where it remained stable until the 1990s, when absolute circulation numbers began declining.
Newspaper circulation numbers are reported to the Alliance for Audited Media. The best-selling papers in America, measured by combined daily average circulation as of March 31, 2013, are the Wall Street Journal with 2,378,827 in circulation; The New York Times at 1,865,318; and USA Today with 1,674,306.
