When using online dictionaries to verify word meanings, do different geographical regions turn to different dictionaries?

Does anyone have a good map of which online dictionary will most likely apply to a given English speaking community?

Solution 1:

I'd say the Oxford English Dictionary is the definitive British English dictionary. Merriam Webster's might be the definitive American English dictionary.

Using Gomez's technique, it seems that the Macquarie Dictionary is the one preferred in Australia.

Solution 2:

Here's a pseudo-scientific, fascinating look at dictionary use by region using Google Trends. For clarity, each phrase was crafted to return a dictionary as the first hit in (American, Western Washington) Google.

Especially interesting are the usage statistics for the Philippines and India, though the former seems heavily skewed by Tagalog search results.

As a bonus, adding the term "Google dictionary" has some interesting results. And if we add Dictionary.com, suddenly things become amazingly skewed.
