More than 155 million U.S. workers have a profile on LinkedIn, and every month more than 3 million jobs are posted on the social media platform, providing it with a huge trove of information on where workers are relocating. Workers typically change their home city on the platform when they relocate for a new job, giving the company insights into where people are moving to and from. Denver is still winning the battle with most other major metros when it comes to drawing more workers than it is losing, according to the LinkedIn Workforce Report for May. Chicago, New York and San Francisco are sending workers in Denver’s direction at the highest rates of any metros this year.
