Lots of Asian countries where familiarity with English is assumed in professional contexts.

> So if your primary gateway to programming languages are ones that slightly resemble a human language you are familiar with you may have lots of psychological blocks keeping you from making that final jump to reasoning in J, or APL, or even a DSL like regular expressions.

That raises the interesting possibility that J or APL might be more appealing to non-English speaking countries, or maybe where the dominant languages are not Indo-European (so not similar to English either). I wonder whether there is any evidence of this?
