Spearman's rank or Pearson's correlation coefficient?

This isn't a GIS question so much but I'd like to correlate the percentage of the population of census output areas who are children with mean distances to green spaces, but am unsure whether to use Spearman's Rank or the Pearson's Correlation Coefficient. I understand that Spearman's rank is best used for ordinal variables, which I don't think either of these 2 are, so perhaps it's better to use Pearson's? But then I've also read that Pearson's is better used when the relationship between variables is linear which I'm not sure it is in this case, so I'm unsure which option's better. Any advice would be much appreciated.
