Does anyone know where influencer databases obtain their demographic data?

Would love to know where influencer databases take all demographics data, any insider here that could explain ?

thanks in advance !

What I do on Instagram is basically scrape using the API the latest posts, bio, email, etc

Using the latest posts location you can know where the influencer is located/target, also by using the phone country code you can know the influencer location.

Then you want to send the bio to an AI to know the specific niche or category

hello i need this please
I need a database/ list of contact info of influencers who have between 300k and 1.2 millions followers. They should be in the fitness and cooking and financial industry. Their content should be a content of value and have good engagement.
The leads should be based in the USA, UK, Canada and Ireland and must speak english.

This is the info needed for each person:
Email/name/account username/followers number/niche and phone number (if possible)

I need between 25K AND 50K leads like this.

It generally includes public data from social media platforms, third-party analysis tools, user surveys, and brand cooperation feedback.

People generally do this by scraping and sorting the data, old people in this industry are the ones who normally have such kind of stuff.
