The New Orleans metro area is estimated to have seen the biggest population loss among those with at least 500,000 residents nationwide, the Census Bureau says.
Why it matters: The metro's 4.3% population loss in the past three years came as the nation's population increased by 1%, according to population estimates from the Census Bureau.
The big picture: Overall, the U.S. population growth was driven by states like Idaho, Florida and South Carolina.
Meanwhile, Louisiana is among the states that had the most declines.
