A Stanford study looked at states where age bias is strongest and found New York to be number five, just below South Carolina, said Fast Company. The study used a data set of 803,009 people between the ages of 15 to 94 to find that the 10 states with the highest amount of age bias are:

1. New Jersey
2. Connecticut
3. Mississippi
4. South Carolina
5. New York
6. Florida
7. North Carolina
8. Georgia
9. Louisiana
10. Maryland

It also found that the 10 states with the lowest amount of age bias are:

1. Utah
2. Alaska
3. Colorado
4. Washington
5. Nebraska
6. Oregon
7. Arkansas
8. Idaho
9. Nevada
10. Vermont
    
    

The study also found that "[h]igher state‐level implicit age bias was associated with poorer state‐level health outcomes among adults ages 65+" and that "[o]lder adults living in states high in implicit age bias showed greater age‐group dissociation compared to older adults living in states low in implicit age bias."
