U.S. population at the beginning of 2017 was over 324 million. 1 U.S. population is growing by over 2,000,000 people per year -- that's 240 per hour -- about half from new births and half from immigration. 1 According to a Global Footprint Network data, the U.S. can sustain a population of only about 150 million at a reduced consumption level similar to Europeans. 2
