# Extracting from files

To do this exercice you will need to download French First name data from "Institut national de la statistique
et des études économiques"

```bash
wget https://www.insee.fr/fr/statistiques/fichier/2540004/nat2021_csv.zip
unzip nat2021_csv.zip 
```

You should now have a file called `nat2021.csv` in your working directory.
