I have to admit that I fell into a rabbit hole, and I noticed that popular tools like fakerjs or gofakeit[0] did not meet my needs.
I needed to generate realistic-looking identities; the person's photo must match the gender, same for the age, the skin color of the person must correspond with the origin of the surname, the first name should be common in the targeted country, and the residential address must be real, among other things.
You would not use this for test data btw, a common use case for this would be for marketing or spamming operations where you need realistic data. My consciense does not accept the later however ;-)
P.S. Nowadays, these fake data generators are too woke to provide genderized first names..
