Since a month, I have been applying to jobs in multiple European countries. In Germany, I had to have a professional help from a German to create "lebenslauf" for private industry and academic jobs. As personal datawise, it includes my birthplace, birthdate, nationality (as I require work permit/job sponsorship) plus I had to have a photo, where you can identify my race, and my gender. As a person living in the US, and keeping the US as a priority, I find this many information, irrelevant to the position and my qualifications, kind of unnecessary and makes me prone to be discriminated, but it is what it is. Moreover, I have also been applying to jobs in the Netherlands, Denmark, and Sweden, and I had friends living/working there and so they know the work ethic and the expectations from a CV or resume. In those countries, I straight out use my "American" CV, which does not include any personal info. Clearly, there is no standard in European countries, I concluded based on four countries I have had experience with.
Also, I have friends who used "just the qualifications - no personal info" regular CV in the Netherlands, Switzerland, and Denmark academic jobs and got hired. So I assume you should check each country if you know someone who is acquainted with the work environment and ethic.
If you don't know anyone, I suggest you couple things before you decide to include certain personal info. If you require work permit, and not a citizen or permanent residency in the country you're applying, including your nationality may be useful. Yet no more than that, because gender, age, marital status are irrelevant; and they make you prone to be discriminated. To further make sure, you may skim the available CVs of professors, postdocs etc. which are available on the university or research lab pages. I think most people have them available in university pages as attachment (at least I have seen most put them), and you can decide whether to include certain personal info or not.
All in all, I don't think in the end it really affects the decision on you being hired as where I was born or whenever I was born or whether I am married with kids or not does not imply how good I am in machine learning, or comparative literature or whatever.
