Demographics change everything

This year, Millennials will overtake Baby Boomers

This year, the “Millennial” generation is projected to surpass the

outsized Baby Boom generation as the nation’s largest living generation, according to the population projections released by the U.S. Census Bureau last month. Millennials (whom we define as between ages 18 to 34 in 2015) are projected to number 75.3 million, surpassing the projected 74.9 million Boomers (ages 51 to 69). The Gen X population (ages 35 to 50 in 2015) is projected to outnumber the Boomers by 2028.
  Lighter areas contain newer construction, while darker areas are older. What stands out immediately is the difference between the Sunbelt--areas in the Southeast and Southwest where growth has been booming--and the Rustbelt--an arc stretching around the Great Lakes from North Dakota to New York. Nebraska and Kansas haven't seen much in the way of new construction either. This tracks pretty well with the overall population change in these areas. Over the past 10 years people have migrated to the Sunbelt and away from the Rustbelt. 

• There were a projected 75.4 million Boomers in 2014. By midcentury, the Boomer population will dwindle to 16.6 million.

By 2050, I think I know where the "huge" numbers of people coming to the NW will 

be living.  Just a wild guess.
