Immigration and Rapid Population Growth

https://DiasporaEngager.com/extPage/InternationalAffairPlatform The Census Bureau has come up with a new population clock on its website that provides access to new population estimates. The population clock shows the U.S. population currently growing by one person every 13 seconds. That is the net growth after subtracting deaths and residents moving out of the country. How many new residents is that a year? It works out to be about 2.43 million population increase a year. So, how much of that increase is due to immigration? The population clock shows that net immigration causes the population to grow by one person every 29 seconds. That works out to 1.09 million persons per year. And, if the rate of increase from immigration is compared to the overall increase, immigration accounts for 45 percent of the increase. But that share is misleading. Immigration accounts or a much larger share: more than three quarters of the increase.
