How good is your Irish geography knowledge? We all think we know the country pretty well, but quizzes like this can catch us out.
We will give you two Irish counties, and you just have to tell us which one has a higher population.
All figures are based on the most recent census that took place, which was 2016 in the Republic of Ireland and 2011 in Northern Ireland.
If the quiz does not display correctly, you can take it here. Best of luck!
