Despite a tight labor market with numerous openings, there’s a growing reluctance to move.

The Wall Street Journal reports Fewer Americans Uproot Themselves for New Jobs.

Fewer Americans are moving around the country to pursue new work opportunities, as a tighter labor market and changing family ties make people less willing to uproot their lives for a job.

About 3.5 million Americans relocated for a new job last year, according to census data, a 10% drop from 3.8 million in 2015. The numbers have fluctuated between 2.8 million and 4.5 million since the government started tracking job-related relocations in 1999—but have been trending lower overall, even as the U.S. population grew by nearly 20% over that stretch.

The share of job seekers relocating for new employment has fallen dramatically since the late 1980s, when more than a third moved to take new opportunities elsewhere, according to surveys from outplacement firm Challenger, Gray & Christmas Inc. In the 1990s, job-related moves ebbed and flowed between 20% and 35%, then fell below 20% after 2000. Roughly 10% of job seekers relocated for new opportunities in the first half of this year, Challenger said.

Not on the Move

Why?

Add it all up and it simply is not worth the disruption.
