Employment discrimination charges filed under the Americans with Disabilities Act (ADA)

Data Source Notes

  • Data files for analysis of charge data were extracted from the Equal Employment Opportunity Commission's (EEOC's) Integrated Mission System (IMS). Summaries of data are based on our aggregations and do not represent the EEOC's official aggregation of the data. The findings and their interpretation do not necessarily represent the policy of the Department of Education or the U.S. Equal Employment Opportunity Commission, and you should not assume endorsement by the Federal Government (Edgar, 75.620 (b)).
  • The confidentiality of the charge data was protected by aggregating the data and suppressing all aggregations representing fewer than 30 charges.
  • The IMS includes charges filed with the EEOC and state and local Fair Employment Practice Agencies (FEPAs). Both EEOC and FEPA (open and closed) charges filed from the beginning of fiscal year 2006 to the end of fiscal year 2014 are included in this analysis. Summaries are at the charge level; however a single charge may cite multiple issues, bases or statutes (e.g., the ADA, the Age Discrimination in Employment Act (ADEA), or Title VII of the Civil Rights Act (Title VII)).
  • The statistics reported in these materials are derived from data files obtained under an agreement from the U.S. Equal Employment Opportunity Commission. Susanne Bruyere obtained an Intergovernmental Personnel Act (IPA) positions at the EEOC, which has afforded her access to the EEOC's Integrated Mission System which includes detailed information on every charge the EEOC receives, as well as those which are dually-filed with FEPAs. Further information about the IPA should be directed to Sarah von Schrader (Email:
  • The U.S. calculations include the 50 states and District of Columbia, but exclude Puerto Rico and other U.S. Territories.
