I can reproduce this... but only to a limited extent.

If I search for "exposiciones" (Spanish, most common word for exhibitions) it will show mainly -but not exclusively- stuff in my city. But if I search for "exhibiciones" (Spanish, equally valid but not the most common word) almost no results will relate to my city. And if I search for "eventos" (Spanish, literally "events", wider meaning than exhibitions but also a more widely used term, I'd guess) none of it will relate to my city.

If I do the same searches directly on Bing, they are always related to my city.

So, my guess is Bing doesn't know about my location through DuckDuckGo, but DDG themselves may be processing Bing's results further depending on my search, which seems likely anyway.
