Working here on the Gulf Coast, it's quite noticeable how few women are in upper management and in primarily technical positions. They're over-represented in areas like project management, quality assurance, and positions with the word "analyst" attached to them. Positions that have the word "engineer" attached to them (systems, network, security, etc.) are almost exclusively male, and software development is about 75% male.
My experience in California... not so much. My employer there had more women in management than men. On my first day my team lead, manager, and division manager were all women. I had female peers/team members throughout my time in engineering roles.
So, in my observation, sexism in IT in the US differs by region, and is expressed quite a bit differently than is seen from other countries/cultures, but it's still very much alive and well.
