Ahead of the pain: Where we stand after a decade of growth in United Council for Neurologic Subspecialties-certified headache subspecialists.

Overall, there has been substantial growth in the number of UCNS-certified headache subspecialists in the US, especially relative to growth in adult headache population. Subspecialist density continues to be highest in the Northeast and is associated with higher per capita personal income. However, there has been encouraging growth in geographies that previously had little to no access. These findings represent positive progress, but there is more to be done to both increase access to optimal headache care by subspecialists nationally and decrease geographic disparities in access to care.
