Only 27% of respondents remain optimistic about the influx of refugees, ZDF reported on Friday.
The survey was conducted after the terrorist attack in Solingen at the end of August, in which a 26-year-old Syrian man went on a stabbing spree, which left three dead and eight injured.
The research results indicate a significant increase in pessimism compared to the survey from March this year. At that time, 55% of respondents believed that the country was not coping with refugees, while 42% were optimistic.
A study by the Infratest Dimap institute commissioned by ARD (Germany's regional public-service broadcasters) shows that the issue of "immigration and refugees" is currently the most important or one of the two most important problems in Germany for 48% of respondents.
The survey shows an increase of 22 percentage points compared to April of this year.
In the wake of the Solingen attack, the first talks have already taken place between the government coalition, the opposition (CDU/CSU) and the federal states on possible changes to migration policy.
Tuesday's round of talks ended without any concrete results. Further talks are to take place next week.
According to the Infratest Dimap survey, 82% of Germans are in favor of expanding prevention and education on radical Islamism, in institutions such as schools and refugee centers.
Of those surveyed, 73% would like to see permanent controls at German borders, and 72% would like to give the German security service additional powers, for example to review electronic communications, including chats.
In 2023, a total of 722,370 migrants applied for asylum in Germany, not including Ukrainians fleeing war in their homeland.
Deutsche Welle reported on a survey conducted by pollster Infratest last year, which found that 78% feel the integration of refugees into the labor market was not working well, while 80% agreed that authorities were failing to carry out deportations of rejected asylum seekers.
