In the UK, this is common. As a hiring manager, I couldn't see the demographic information provided by candidates. If a candidate didn't volunteer the info, I also didn't know. It made zero difference to whether a CV was passed to me. But, after a hiring campaign had been run, it was possible to see the aggregate of that demographic data. That can be useful in finding out if fewer people of type X are applying for a role, or if statistically more of type Y get a role, etc. If you showed up to interview wearing a religious garment, while visibly pregnant, dressed in your service uniform, and talked about your experience as a gay immigrant - I wouldn't be able to discriminate against you on those characteristics. But unless I was stupid enough to write that down in an email, it would be hard to prove. In short, no, it doesn't reflect badly on you and it doesn't impact the hiring process.
