The U.S. population is projected to grow more slowly over the next 30 years than previously predicted. That's according to a report Wednesday by the Congressional Budget Office. That slowing is due President Donald Trump's strict immigration policies and a projected lower fertility rate. The country’s total population is projected to stop growing in 2056 and remain roughly the same size as in the previous year. But without immigration, the population would begin to shrink in 2030 as deaths start to exceed births. That would make immigrants an increasingly important source of population growth. Trump has pushed for the largest mass deportation campaign in history.
