"They are not [in favor of] kicking out [those] who are here," says Walid Alkhatib, head of the center's polling unit. "But they are saying: this is enough for us. This is our capacity, that's it."
The survey, conducted at the end of August, is the first to measure Jordanian's attitudes toward refugees. As such, Mr. Alkhatib warns, it cannot be taken as a measure of change. But there are indications that the country's mood is growing darker.
"Yesterday there were clashes between the security and the refugees in the camp," Alkhatib says. "So there is a lot of tension. If we had conducted the survey today, we might receive even, not 65 percent, maybe 70 percent [overall]."
The survey also found the largest constituency in favor of closing the border, 88 percent, in the governorate of Mafraq, where the Za'atari refugee camp is located.
There are also indications that Jordanian's feelings about the Syrian uprising as a whole are growing more negative. In focus groups done earlier in the year, Alkhatib says there was a clear perception of the Syrian conflict as "a revolution against the regime." By August, however, 45 percent of respondents to the survey said the situation was an "external conspiracy against Syria."
"People were in favor of seeing [Syria's] revolution, when it was a peaceful revolution," Alkhatib says. "When it comes to armed revolution, people start wondering: is it a revolution or not a revolution? Is it something sponsored by the West, because they want to change the regime, or is it something coming actually from inside Syria?"
