ExampleAccording to a 2012 study, about 3% of the population of Ireland speak Irish as their first language, and about 16% of the population of Luxembourg speak French, does this mean that there are more French speakers in Luxembourg than there are Irish speakers in Ireland?Well, no. We need to know the populations of Ireland and Luxembourg in order to answer this question. In 2012, the population of Ireland was approximately 4.5 million, meaning there were approximately 135,000 people speaking Irish as their first language. By comparison, in 2012, the population of Luxembourg was about half a million, meaning there were about 80,000 French speakers in Luxembourg.Whilst the proportion was greater in one country, ‘the whole’ population was much lower. Percentages must be considered with respect to ‘the whole’.
