I'm trying to find reliable data on attacks on refugee homes in Germany/Poland in recent years. I know that there were several projects initiated to collect such data, however so far I can't find the output anywhere. All suggestions are welcome.
There's a badly maintained (not consistently formatted) table on Wikipedia: Liste von Angriffen auf Flüchtlinge und Flüchtlingsunterkünfte in Deutschland 2015
There's a project bei ZEIT which collected cases, but afaik never published the data: Es brennt in Deutschland
Are there any other official/community-driven data bases?
I don't want state-level aggregates
