The Census Bureau’s U.S. and World Population Clock lists “components of population change” on the website: “one birth every 7 seconds;” “one death every 13 seconds;” “one international migrant (net) every 40 seconds;” making for a “net gain of one person every 12 seconds.”

The Census provides some background on the immigration debate in the United States on August 3rd, apropos of the 131st anniversary of the law banning people from immigrating to the United States if they were likely to need government assistance.
