From my own experience, I recognized that the number of vacation days can vary quite a bit depending on which country you work in. Mercer Consulting has researched the number of days off work among different countries, with Canada and the U.S. having a relatively low number of days off annually compared to other countries like Brazil and Lithuania, having up to twice as much off. See a list of selected country below:

Brazil: 30 days plus 11 days of public holidays. Total: 41

Lithuania: annual minimum of 28 off and 13 public holidays. Total: 41

France: minimum of 30 days off and 10 days of public holidays. Total: 40

Russia: statutory minimum of 28 days plus 12 days for public holidays. Total: 40

But before you quit your job and move to another country in the hope of more vacation, you should know that these are just minimum requirements, and companies often have some discretion on how much vacation they offer their employees. Therefore it might be worth checking out some companies in your home country first
