How can I change my personal data address?

Log in to the CBS microdata portal and click on "My personal data," then click on "Modify." Modify your data and click "Modify" at the bottom of the page to save the changes. Note: you can change your email address for communication, but not your email address for the portal access. This email address is your username for logging in to the portal and is linked to your institution. If that changes you need to create a new account.
