52.0 percent — Percentage of the US population that lives in RTW states. With Kentucky and Missouri adding new laws, over half of Americans live in states where paying a union can not be a job requirement.  

494,000 — The number of people that moved from non-RTW states to RTW states. Opportunity is an important factor for why people move from one place to another.

2nd — Michigan had the second highest gains in per-capita personal income since passing its RTW law at the end of 2012. So much for "Right-to-Work for less."
