Hi Marco, when I did this project, I also brought out the factors of my own and searched for datasets. One important note is that I looked for national average (without gender) to be in line with the target variable.

Not all datasets are available, but the internet has vast resources.

You could search these potential resources:

- Kaggle

- dataquest.io

- https://datasetsearch.research.google.com/

- government data eg. https://www.stats.govt.nz/ or https://data.gov.sg/

Alternatively you could consult search engines eg. Google! Do try various key words to reach the right sites.

All the best to your project!
