LGBTQ Data Inclusion Act This bill requires federal agencies that collect information through a survey that includes demographic data (where subjects self-report information or a proxy provides information about the subject or responds for all persons in a household) to review existing data sets to determine in which data sets information about sexual orientation and gender identity is not included, and to assess needed changes in survey methods related to asking questions on sexual orientation and gender identity. Agencies that publish reports relying on survey demographic data must include information on sexual orientation and gender identity.
