There is a seminal paper showing how carelessly adopting this point of view can lead to disasters: "87% of the U.S. population is uniquely identified by date of birth, gender, postal code" [1]

In many other cases, as pointed out, it's just not possible. I'm studying mobility patterns through cellphone metadata. Even if you strip out the actual phone number with a random ID you still know where a person is going, and thus re-identify them if you have other public data.

full name + date of birth + place of birth.

That leaves about 500 non unique individuals in a country of > 50 million inhabitants.
