The analysts used reports from local media, mainstream media and the police to compile a map of crimes across Germany, including sexual assault, attempted rape, robbery and criminal assault. The map shows the town in which the attack happened but it doesn't mark the exact spot.
These crimes were then compared with another map showing the location of Germany's asylum reception centers.
Comparison of the two maps appears to reveal correlation between the presence of an asylum reception center and the proportion of sex offences in the vicinity of the center.

Within a two kilometer radius of an asylum reception center, there was an average of 476 reported sex crimes, or 21.82 percent of all the crimes reported. Within a ten kilometer radius there were 11,154 reported sex crimes, or 15.80 percent of all the crimes reported.
The data appears to show that the proportion of sex offenses declines further away from asylum reception centers. Within a radius of ten to 15 kilometers from asylum centers the proportion of sex crime falls to 8.53 percent. Between 40 and 50 kilometers away from asylum reception centers, the proportion of sex offenses falls to 1.19 percent.

The group of activists who made the map call themselves XY-Einzelfall because Einzelfall, which means 'isolated case' in German, is a term often used by the German police and media to underplay the extent of migrant crime.
"We decided to make the map because the German press is staying silent, they are only reporting selectively, not the whole disaster," XY-Einzelfall told Sputnik.
"The only Police-related person who addresses the issue in the press without whitewashing it is Rainer Wendt, head of the German Police Union."
XY-Einzelfall aim to inform Germans about the dangers of Angela Merkel's policies.
"We aren't trying to tell anybody what to do. We just want people to be alert to the huge danger around them. The biggest news show in Germany didn't even mention the (recent) homicide in Freiburg and that the perpetrator who raped and killed the girl is a refugee."
The influx has led to concern about increased crime rates, which has boosted support for the anti-immigration Alternative for Germany.
According to German police statistics, in 2015 there were 6.33 million recorded crimes in Germany, a 4.1 percent increase compared to 2014.
In Germany in 2015 there were 46,081 reported sex crimes, or 0.8 of the total offenses recorded.
The police statistics show a staggering 158.3 percent increase in the number of non-Germans suspected of committing crime, including asylum seekers, compared to the previous year.
In 2014 non-Germans were suspects in 179,563 crimes, or 8.4 percent of all recorded crimes. In 2015 non-Germans were suspects in 463,889 crimes, or 26 percent of all crimes.
