Attacks against refugee settlements reached 274 compared to 136 just three months ago, meaning the number has doubled in the third quarter of 2015, the "Saarbrücker Zeitung" newspaper revealed on Saturday.
Reports indicate Neo-Nazi organizations have been attracting significantly more followers, which has resulted in larger demonstrations. More than 5,800 people participated in anti-refugee demonstrations between July and September.
"Protests against refugees are now used by Nazis as a central theme to mobilize," German politician and Bundestag member Ursula Jelpke told journalists.
Demonstrations have included members from the National Democratic Party (NPD) and the Third Way but have excluded the anti-Islamization Pegida movement.
The soaring number of protesters is explained by the estimated million asylum seekers fleeing from civil war in Syria expected to come to Germany by the end of the year.
September alone has witnessed 1,380 right-wing inspired crimes and 104 attacks all across Germany, according to Die Linke politician Petra Pau.
Some 203 anti-Semitic attacks have been registered between July and September, or nearly two per day.
