The diffusion of federal Title IX complaints throughout U.S. colleges and universities, 1994-2014

This article uses an original dataset of federal Title IX complaints to assess whether and how mobilization of the law to confront sexual harassment has diffused throughout four-year (and above) nonprofit colleges and universities. Event history analyses show that complaints spread more rapidly among schools of similar selectivity as well as among institutions linked by a new indicator for social proximity-school Twitter ties-that encompasses multiple forms of social proximity simultaneously. The same diffusion patterns do not emerge for other types of sex discrimination complaints filed under Title IX, indicating that networks channel the capacity to mobilize law differently across different types of claims. The findings illuminate a dramatic transformation in the deployment of Title IX that has reshaped how colleges and universities govern gender relations.
