Set your clocks and mark your calendars, because at 7:46 a.m. Tuesday, America will reach a milestone.
That's when the Census Bureau calculates that the United States population will hit 300 million.
It comes only 39 years after our country hit 200 million back in 1967.
The population clock is based on an algorithm using birth, death and immigration.
According to the United States Census, a new American is born every seven seconds, an American dies every 13 seconds, and international migration adds one person every 31 seconds.
If you add it together, it equals one extra person every 11 seconds.
Totaling 300-million by next Tuesday.
Dudley Poston, a demographer with the Sociology Department at Texas A&M University, says it's no surprise.
"We're getting about 1.9 million people a year via the difference between births and deaths and about 1 million via immigration," Poston said.
In 1915, the United States population passed the 100 million mark.
52 years later the population grew to 200 million, and 39 years later the United States population will hit 300 million.
"Without immigration we would be looking like Italy and Spain with a fertility rate of probably of about 1.6 or 1.5 maybe a little bit higher, and we would be losing population in the future," Poston said.
The 300 millionth person might be a baby born or it could be an immigrant entering the country.
About 53 percent of the 100 million extra Americans are recent immigrants or their descendants, and Immigration has been a hot button issue.
If you're worried we're running out of room, rest easy.
Statistics show the United States is among the world's least populous nations.
Resources may be limited in the future, but for now, eyes will just be fixed on the Census Bureau's population clock ticking closer to the historic milestone.
The United State's population may seem high, but America is the third most populous country in the world after China and India.
Statistics show Americans are expected to continue to gravitate west and south. The great American midsection, meanwhile, will continue to empty out.
