The Difficult Work Of Measuring Anti-Semitism In Europe | FiveThirtyEight

Good piece on the challenges of collecting hard reliable data, in the absence of police-reported hate crimes (which both UK and Canada do), particularly with respect to social media:

Social media is one factor that complicates comparisons over time. One in 6 of the incidents this year through June were abusive comments on social media, a forum that scarcely existed a decade ago.

Rich said CST [UK’s Jewish Community Security Trust] sets a high bar for counting an anti-Semitic post on social media: It must have been reported to the group, and must originate from or be directed to someone in the U.K. “We’ve had to think quite a lot about how to develop processes for dealing with this,” Rich said. “Potentially the number of anti-Semitic tweets and Facebook comments could completely overwhelm our incident reports and make them completely meaningless.”

Groups like CST help supplement government statistics on hate crimes, which are inconsistently kept in the European Union. Only five of the 28 EU countries, including the U.K., have comprehensive data on racist crimes and hate crimes against Jews, Muslims and Roma people, according to a December analysis by the European Union Agency for Fundamental Rights, or FRA.

“FRA has reiterated the necessity for EU member states to improve their data-collection methods,” Katya Andrusz, a spokeswoman for FRA, said in an email. “The agency has also called for member states to take measures to increase trust in the police and other authorities, as the two big challenges in gauging the extent of anti-Semitism are underrecording and underreporting, i.e. even when countries have the mechanisms in place to note the number of anti-Semitic incidents taking place, most victims don’t report them.”

Many of the articles about the rise in anti-Semitism cited a 2012 online survey of Jews in eight EU countries, conducted by FRA, finding that 2 in 3 respondents said anti-Semitism is a problem in their country. The survey, though, was the first of its kind, so it can’t say whether European Jews were reporting more anti-Semitism in 2012 than they had before. FRA is considering conducting another survey in several years. “There are preliminary plans to do another one, precisely for the reason you say” — i.e. that there is no trend data, Andrusz said. She added, “It’s impossible to say whether anti-Semitism is statistically on the rise in the EU, as the data simply doesn’t exist.”
