I thought the same thing about catholicism in Mexico. It seems like Mexico was already rich with their own history and traditions and various cultures, and now this religious symbol is so prominent in the country and it was because of Spanish missionaries. I'm also atheist so that's a factor.

The data is an aggregate but it's a very different thing for one person to travel to a specific place and observe things from the literal ground floor. But as stated the data is based on searches not people or real interest. It's possible many of those searches were conducted by the same people.
