Not surprisingly, most are tied to manufacturing areas hard hit by the economy.

The economic website  published a report this week taking a look at the ten U.S. communities that have seen the biggest percentages of population loss. They also factored in average household income, and whether it's gone up, or down.

Many of the areas are in Ohio, Pennsylvania, and West Virginia.  Some are tied to the decline of the coal industry, several accelerated by the GM bankruptcy in 2009.   In the U.S., overall manufacturing jobs (autos, products, machinery etc) have dropped some 30% between 2001 and 2013.   But these areas have even been harder hit, according to

"However, in eight of the areas with shrinking populations, the number of jobs in the manufacturing sector fell by more than the nationwide decline, according to figures produced by Economic Modeling Specialists Intl. (EMSI). Flint, Michigan, lost the most jobs in the sector as manufacturing employment declined 57% from 2001 to 2013."

The list includes a city in Nevada, one in New Mexico, but the bulk are in the Upper Midwest and East.  Click Here to see the list.     And one clue, you probably don't want to move to Ohio anytime soon.

As for Tri-Cities, we're nowhere near being on any such list,  Nor are there any towns within 1,000 miles of Washington state.
