Some 58 percent said they didn't plan to send money to help the more than 20 million people displaced by the disaster in the country, according to the survey taken by Infratest dimap for broadcaster ARD.
Just 12 percent of those questioned said they had already made a charitable contribution after getting word of the devastating floods that followed heavy monsoon rains. Another 24 percent said they planned to donate money soon.
These numbers are low compared to a similar poll taken following the 2005 tsunami, when 62 percent said they had already donated and 22 percent said they planned to do so.
When the current poll asked participants their reasons for not donating, 40 percent said it was because they didn't have enough money themselves. Another 29 percent said they did not believe the money would make it to the right place. Eight percent said they never make charitable contributions, and seven percent said Pakistan was too culturally different to imagine making a donation there, ARD said.
Three percent said they felt Germany's problems were more important, and two percent said lawmakers were responsible for taking care of the situation. Another two percent said they did not trust Pakistan.
The poll questioned 1,000 representative citizens between August 17 and 18.
