You will be given a definition of a task first, then some input of the task.
This task involves annotating the answer type to a given question that involve some kind of complex reasoning (including numerical reasoning). Note that the questions require looking at more than one part of the passage to answer. There are 3 possible answer types (i) spans, (ii) numbers and (iii) dates. If the answer can be found in the passage, label it as "span". If the answer is a number, label as "number". Similarly, label "date" if you think the answer to the given question is a date.

Passage: The difference in Gini indices between Organisation for Economic Co-operation and Development countries, on after-taxes and transfers basis, is significantly narrower. For OECD countries, over 20082009 period, Gini coefficient on pre-taxes and transfers basis for total population ranged between 0.34 and 0.53, with South Korea the lowest and Italy the highest. Gini coefficient on after-taxes and transfers basis for total population ranged between 0.25 and 0.48, with Denmark the lowest and Mexico the highest. For United States, the country with the largest population in OECD countries, the pre-tax Gini index was 0.49, and after-tax Gini index was 0.38, in 20082009. The OECD averages for total population in OECD countries was 0.46 for pre-tax income Gini index and 0.31 for after-tax income Gini Index. Taxes and social spending that were in place in 20082009 period in OECD countries significantly lowered effective income inequality, and in general, "European countriesespecially Nordic and Continental welfare statesachieve lower levels of income inequality than other countries."
Question: Which country had a higher Gini coefficient on after-taxes and transfers basis for total population, Denmark or Mexico?
