The two countries with the greatest shares of the world's Jewish population are the United States and Israel. The United States had been a hub of Jewish immigration since the nineteenth century, as Jewish people sought to escape persecution in Europe by emigrating across the Atlantic. The Jewish population in the U.S. is largely congregated in major urban areas, such as New York, Los Angeles, and Chicago, with the New York metropolitan area being the city with the second largest Jewish population worldwide, after Tel Aviv, Israel. Israel is the world's only officially Jewish state, having been founded in 1948 following the first Arab-Israeli War. While Jews had been emigrating to the holy lands since the nineteenth century, when they were controlled by the Ottoman Empire, immigration increased rapidly following the establishment of the state of Israel. Jewish communities in Eastern Europe who had survived the Holocaust saw Israel as a haven from persecution, while the state encouraged immigration from Jewish communities in other regions, notably the Middle East & North Africa. Smaller Jewish communities remain in Europe in countries such as France, the UK, and Germany, and in other countries which were hotspots for Jewish migration in the twentieth century, such as Canada and Argentina.

This statistic shows the top 25 countries in the world with the largest number of Jewish population in 2010. In 2010, there were living about 5.7 million Jews in the United States.

The average for 2013 based on 21 countries was 4.3 percent. The highest value was in Israel: 76.2 percent and the lowest value was in Hungary: 0.2 percent. The indicator is available from 1960 to 2013. Below is a chart for all countries where data are available.

The world's Jewish population has had a complex and tumultuous history over the past millennia, regularly dealing with persecution, pogroms, and even genocide. The legacy of expulsion and persecution of Jews, including bans on land ownership, meant that Jewish communities disproportionately lived in urban areas, working as artisans or traders, and often lived in their own settlements separate to the rest of the urban population. This separation contributed to the impression that events such as pandemics, famines, or economic shocks did not affect Jews as much as other populations, and such factors came to form the basis of the mistrust and stereotypes of wealth (characterized as greed) that have made up anti-Semitic rhetoric for centuries. Development since the Middle Ages The concentration of Jewish populations across the world has shifted across different centuries. In the Middle Ages, the largest Jewish populations were found in Palestine and the wider Levant region, with other sizeable populations in present-day France, Italy, and Spain. Later, however, the Jewish disapora became increasingly concentrated in Eastern Europe after waves of pogroms in the west saw Jewish communities move eastward. Poland in particular was often considered a refuge for Jews from the late-Middle Ages until the 18th century, when it was then partitioned between Austria, Prussia, and Russia, and persecution increased. Push factors such as major pogroms in the Russian Empire in the 19th century and growing oppression in the west during the interwar period then saw many Jews migrate to the United States in search of opportunity.

The Pew Research Center Survey of U.S. Jews 2013, is a comprehensive national survey of the Jewish population. The survey explores attitudes, beliefs, practices and experiences of Jews living in the United States. There are two datasets, a respondent dataset (where there is one row per respondent) and a household dataset (where there is one row per person in the sampled households). The respondent dataset includes all of the information collected as part of the survey. The household dataset is a reshaped version of the respondent dataset that includes a limited number of variables describing the demographic characteristics and Jewish status of all of the people in the surveyed households.

In the Middle Ages, it is believed the largest Jewish populations in the world were found in Asia, particularly across the Middle East. Of the estimated total Jewish population of 1.2 million people, over 80 percent are thought to have lived in Asia, while 13 percent lived in Europe, and the remaining six precent lived in (North) Africa. The largest populations were found on the Arabian peninsula, as well as Iran and Iraq, while the Near East (here referring to the Levant region) had a much smaller population, despite being the spiritual homeland of the Jewish people.

These figures are based on the records of Benjamin of Tudela, a Jewish traveller from the Middle Ages who provided one of the most comprehensive collections of population statistics from the period. Benjamin's writings not only recorded the number of Jews living across this part of the world, but also gave an insight into societal structures and the ordinary daily lives within Jewish communities in the medieval period. The source providing these figures, however, has adjusted some of the statistics to account for known populations that were missing from Benjamin of Tudela's records, especially in Europe and Asia.

The Holocaust was the systematic extermination of Europe's Jewish population in the Second World War, during which time, up to six million Jews were murdered as part of Nazi Germany's "Final Solution to the Jewish Question". In the context of the Second World War, the term "Holocaust" is traditionally used to reference the genocide of Europe's Jews, although this coincided with the Nazi regime's genocide and ethnic cleansing of an additional eleven million people deemed "undesirable" due to their ethnicity, beliefs, disability or sexuality (among others). During the Holocaust, Poland's Jewish population suffered the largest number of fatalities, with approximately three million deaths. Additionally, at least one million Jews were murdered in the Soviet Union, while Hungary, Latvia, Lithuania, the Netherlands and Yugoslavia also lost the majority of their respective pre-war Jewish populations. The Holocaust in Poland In the interwar period, Europe's Jewish population was concentrated in the east, with roughly one third living in Poland; this can be traced back to the Middle Ages, when thousands of Jews flocked to Eastern Europe to escape persecution. At the outbreak of the Second World War, it is estimated that there were 3.4 million Jews living in Poland, which was approximately ten percent of the total population. Following the German invasion of Poland, Nazi authorities then segregated Jews in ghettos across most large towns and cities, and expanded their network of concentration camps throughout the country. In the ghettos, civilians were deprived of food, and hundreds of thousands died due to disease and starvation; while prison labor was implemented under extreme conditions in concentration camps to fuel the German war effort. In Poland, six extermination camps were also operational between December 1941 and January 1945, which saw the mass extermination of approximately 2.7 million people over the next three years (including many non-Poles, imported from other regions of Europe). While concentration camps housed prisoners of all backgrounds, extermination camps were purpose-built for the elimination of the Jewish race, and over 90% of their victims were Jewish. The majority of the victims in these extermination camps were executed by poison gas, although disease, starvation and overworking were also common causes of death. In addition to the camps and ghettos, SS death squads (Einsatzgruppen) and local collaborators also committed widespread atrocities across Eastern Europe. While the majority of these atrocities took place in the Balkan, Baltic and Soviet regions, they were still prevalent in Poland (particularly during the liquidation of the ghettos), and the Einsatzgruppen alone are estimated to have killed up to 1.3 million Jews throughout the Holocaust. By early 1945, Soviet forces had largely expelled the German armies from Poland and liberated the concentration and extermination camps; by this time, Poland had lost roughly ninety percent of its pre-war Jewish population, and suffered approximately three million further civilian and military deaths. By 1991, Poland's Jewish population was estimated to be just 15 thousand people, while there were fewer than two thousand Jews recorded as living in Poland in 2018.

Throughout history, the displacement and migration of Jewish populations has been a repeating theme. In ancient times, the worlds Jewish population was concentrated in the Middle East, especially around Judaism's spiritual homeland in present-day Israel. However, the population distribution of the world's Jewry began to shift in the Middle Ages, with an increasing share living in Europe. Initially, Western Europe (particularly France, Italy, and Spain) had the largest Jewish populations, before they then migrated eastward in later centuries. Between the 18th and mid-20th centuries, over half of the worl'd Jews lived in Europe, with over 80 percent of these living in Eastern Europe.

Poland had become a refuge for Jews fleeing persecution in the Middle Ages, although shifting borders and foreign influence meant that long-term security was never fully attained, and a series of pogroms in the Russian Empire in the 1800s, and rising anti-Semitism in Central Europe in the early-1900s contributred to waves of migration to the United States and Israel during this time. After the Holocaust saw the genocide of up to six million Jews (over one third of the world's Jewish population), the share of Jews living in Europe dropped drastically, and emmigration outside of Europe increased. Today, the United States has the world's largest Jewish population in the world at around 7.3 million people, just ahead of Israel with 7.1 million.

The survey provides comparable data on the perceived extent and nature of antisemitism across a number of selected EU Member States, whether it is manifested as hate crime, hate speech, discrimination or in any other form that undermines Jewish people’s feelings of safety and security. The survey was commissioned by the European Union Agency for Fundamental Rights (FRA). It follows up on the agency’s first survey, conducted in seven countries in 2012.

The overall objectives of FRA’s second survey on discrimination and hate crime against Jews in the European Union (EU) are 1) to collect comparable data in the selected EU Member States and thereby contributing to the assessment and further development of policies that aim to protect the fundamental rights of Jewish people living in the EU; 2) to identify changes over time with respect to the results of the first survey on discrimination and hate crime against Jews in 2012; 3) to further develop research methodologies for surveying hard-to-reach groups using online survey tools; 4) to deliver FRA’s key stakeholders research evidence that can be used to raise awareness of fundamental rights and address gaps in the protection of rights.

The 2018 survey collected data from 16,395 self-identified Jewish respondents (aged 16 or over) in 12 EU Member States – Austria, Belgium, Denmark, France, Germany, Hungary, Italy, the Netherlands, Poland, Spain, Sweden, and the United Kingdom. These Member States are home to over 96 % of the EU’s estimated Jewish population. The survey collected data through an open online survey and was available for respondents to complete for seven weeks in May–June 2018.

The survey asked respondents about their opinions on trends in antisemitism, antisemitism as a problem in everyday life, personal experiences of antisemitic incidents, witnessing antisemitic incidents and worries about becoming a victim of an antisemitic attack. The survey also provides data on the extent to which respondents consider antisemitic acts against the Jewish community – such as vandalism of Jewish sites or antisemitic messages in the broadcast media or on the internet – to be a problem in the countries. The survey collected data on the effects of antisemitism on respondents’ daily behaviour and their feelings of safety, and about any actions they take due to security fears. The questions about personal experiences of specific forms of harassment or physical violence were followed up with questions concerning the details of such incidents, including their frequency, the number and characteristics of perpetrators, and the reporting of the incident to any organisation or institution. The survey collected data about personal experiences of feeling discriminated against on different grounds and in various areas of everyday life – for example, at work, school, or when using specific services. The survey followed up on respondents’ discrimination experiences with questions concerning the reporting of incidents and the reasons for non-reporting. The survey also explored the level of rights awareness regarding antidiscrimination legislation, victim support organisations and knowledge of any legislation concerning the trivialisation or denial of the Holocaust. In addition, the survey collected socio-demographic data, such as respondents´ gender and age, educational background, employment status, and income.

Between Oct. 14, 2014, and May 21, 2015, Pew Research Center, with generous funding from The Pew Charitable Trusts and the Neubauer Family Foundation, completed 5,601 face-to-face interviews with non-institutionalized adults ages 18 and older living in Israel.

The survey sampling plan was based on six districts defined in the 2008 Israeli census. In addition, Jewish residents of West Bank (Judea and Samaria) were included.

The sample includes interviews with 3,789 respondents defined as Jews, 871 Muslims, 468 Christians and 439 Druze. An additional 34 respondents belong to other religions or are religiously unaffiliated. Five groups were oversampled as part of the survey design: Jews living in the West Bank, Haredim, Christian Arabs, Arabs living in East Jerusalem and Druze.

Interviews were conducted under the direction of Public Opinion and Marketing Research of Israel (PORI). Surveys were administered through face-to-face, paper and pencil interviews conducted at the respondent's place of residence. Sampling was conducted through a multi-stage stratified area probability sampling design based on national population data available through the Israel's Central Bureau of Statistics' 2008 census.

The questionnaire was designed by Pew Research Center staff in consultation with subject matter experts and advisers to the project. The questionnaire was translated into Hebrew, Russian and Arabic, independently verified by professional linguists conversant in regional dialects and pretested prior to fieldwork.

The questionnaire was divided into four sections. All respondents who took the survey in Russian or Hebrew were branched into the Jewish questionnaire (Questionnaire A). Arabic-speaking respondents were branched into the Muslim (Questionnaire B), Christian (Questionnaire C) or Druze questionnaire (D) based on their response to the religious identification question. For the full question wording and exact order of questions, please see the questionnaire.

Note that not all respondents who took the questionnaire in Hebrew or Russian are classified as Jews in this study. For further details on how respondents were classified as Jews, Muslims, Christians and Druze in the study, please see sidebar in the report titled "http://www.pewforum.org/2016/03/08/israels-religiously-divided-society/" Target="_blank">"How Religious are Defined".

Following fieldwork, survey performance was assessed by comparing the results for key demographic variables with population statistics available through the census. Data were weighted to account for different probabilities of selection among respondents. Where appropriate, data also were weighted through an iterative procedure to more closely align the samples with official population figures for gender, age and education. The reported margins of sampling error and the statistical tests of significance used in the analysis take into account the design effects due to weighting and sample design.

In addition to sampling error and other practical difficulties, one should bear in mind that question wording also can have an impact on the findings of opinion polls.

The Jewish School Study was undertaken to determine the advantages and disadvantages of different forms of Jewish education, how Jewish day schools are formed and organized, how Jewish schools contribute to the maintenance of continuity of a 400-year tradition, how adolescent Jews develop their identity, and what role religious education plays in this development. Questions also asked how Jewish adolescents and their parents participate in Jewish life, express their feelings about being Jewish, the role of spirituality in their lives, how they learn about Jewish life, and their relationship/ties with Israel and the Jewish people. Part 1, the Parent Survey, asked parents of students in Jewish schools about the financial costs of religious education, their religious background, Jewish religious practices of their household, as well as their own religious beliefs and spirituality. The survey also sought answers to questions on the parents' reasons for their choice of Jewish school, how involved and in what ways they were involved in their child's school and education, their involvement in the Jewish community, their level of knowledge on various subjects related to Judaism, and their opinions on their own parenting. Other information collected included marital status, income, family status, family origins, education, and employment. Part 2, the Student Survey, asked students about their religious background, the religious practices and experiences in their household, and their own Jewish practices. Students were then asked about how they spent their free time on Saturdays and weekdays, how they and their parents felt about being Jewish, and what types of rules their parents had for them. Additionally, students were queried about their values, friends, and future plans; knowledge of various subjects relating to Judaism; and their opinions of their school, teachers, and their own academic performance. Background information collected included gender, grade in school, name and types of schools attended, household composition, language spoken in the home, and parents' education and employment. Part 3, the Teacher Survey, asked teachers about the settings they worked in and the salary and benefits of those positions. Respondents also were asked about the classes they taught, the use of various teaching methods and media, and their roles and responsibilities. The survey also asked the teachers about their training and professional development, their perceptions and attitudes about their school, parental involvement, resources and facilities, and school goals. Additionally, teachers were asked about their religious background, Jewish religious practices of their own households, and their personal religious beliefs and spirituality. Background information collected included type of postsecondary education, gender, age, place of birth, marital status, income, and future career plans.

The Freikorps Grün Loudon started as a German mercenary formation raised in spring 1790 to provide the Habsburg army with a light infantry force against the short-lived Brabant Republic. The Freikorps continued to serve during the First Coalition War against Revolutionary France (1792-97). As the conflict dragged on, the Rhineland, which served as its primary recruitment area was occupied by the enemy. As a result, the Freikorps shifted its main recruitment efforts to the Habsburg province of Galicia where a large Jewish population lived. The first Jews volunteers were enlisted in spring 1796. Within a year, Jewish soldiers comprised more than one per cent of the unit's strength. This proportion was kept until the Freikorps was disbanded in summer 1798.

With a total number of 27 individual entries, this dataset covers every single Jewish soldier who served in the unit. In addition to basic bibliographical information, the dataset includes reconstructions of complete service itineraries. Some of these are so detailed that the whereabouts and doings of individual soldiers could be traced month after months. After Freikorps Grün Loudon was disbanded, 22 surviving Jewish veterans were transferred to the 3rd and 4th Light Infantry Battalions. Their subsequent service and eventual fates are covered as well. In the dataset includes partial information about three spouses and two children, whose their existence can be discerned from soldiers' personal records.

In terms of their service experiences, the Jewish members of the Freikorps Grün Loudon did not differ much from other mercenary soldiers of that period. As implied by their name, Freikorps units did not form part of the standing army. Manned by foreign renegades and local volunteers, their soldiers were considered more expandable, and Freikorps used to suffer high combat losses. Tactically, Freikorps were often divided into small raiding detachments, which meant their soldiers often remained outside of the direct supervision of their officers. This resulted in high desertion rates. At the same time, the Freikorps also had a committed core of highly-dedicated professional soldiers. Among the veterans of the Freikorps Grün Loudon was Samuel Prager – one of the first documented Jewish soldiers in modern history to rise to the rank of Company Sergeant Major.

During the Holocaust, approximately six million Jews were killed. In France, the Jewish population had decreased by ******* individuals between 1939 and 1945. It then increased between the end of World War II and the 1970s, reaching ******* individuals in 1970. However, according to the source, the number of Jews in France has declined by more than 15 percent between that period and 2020, and is now estimated to be *******.

This dataset comes from Footprints: Jewish Books Through Time and Place. Data includes provenance data (names, dates, locations) related to editions (title, publication date, publication place, standard identifier) of specific works (title, author) and related notes. The hierarchy for the dataset is composed of "footprints" which are found in "copies" of "imprints" of "literary works," with "footprint being the most specific data point and "literary work" being the most general. Wherever possible, the standard identifier for imprints is the Bibliography of the Hebrew Book. Downloaded on July 1, 2022.

This study applied causal modeling to address a controversy regarding the Holocaust in the Netherlands: The Jewish Council issued temporary exemptions intended to delay the deportations of Jews, though some scholars contended that these facilitated deportations. To assess the impact of temporary exemptions on deportation, data on exemption status, hiding or fleeing, and deportation were collected for a random sample of nearly 400 Amsterdam Jews. Calculating conditional probabilities (Tree diagram) and applying Pearl’s front-door criterion (causal diagram) indicate that the average causal effect of temporary exemption is about a 10-percentage-point reduction in deportation chance. This research demonstrates that utilizing statistical methods such as causal modeling on collected life trajectory data for Jewish survivors and victims can enhance our understanding of the Holocaust.

In 2020, Mexico had a Jew population of ****** people. More than a third of that population lived in Mexico State by that time. Mexico City had almost ****** Jewish people in this same year.

Institute for the Study of Contemporary Antisemitism (ISCA) at Indiana University Dataset on bias against Asians, Blacks, Jews, Latines, and Muslims

The ISCA project compiled this dataset using an annotation portal, which was used to label tweets as either biased or non-biased, among other labels. Note that the annotation was done on live data, including images and context, such as threads. The original data comes from annotationportal.com. They include representative samples of live tweets from the years 2020 and 2021 with the keywords "Asians, Blacks, Jews, Latinos, and Muslims". A random sample of 600 tweets per year was drawn for each of the keywords. This includes retweets. Due to a sampling error, the sample for the year 2021 for the keyword "Jews" has only 453 tweets from 2021 and 147 from the first eight months of 2022 and it includes some tweets from the query with the keyword "Israel." The tweets were divided into six samples of 100 tweets, which were then annotated by three to seven students in the class "Researching White Supremacism and Antisemitism on Social Media" taught by Gunther Jikeli, Elisha S. Breton, and Seth Moller at Indiana University in the fall of 2022, see this report. Annotators used a scale from 1 to 5 (confident not biased, probably not biased, don't know, probably biased, confident biased). The definitions of bias against each minority group used for annotation are also included in the report. If a tweet called out or denounced bias against the minority in question, it was labeled as "calling out bias." The labels of whether a tweet is biased or calls out bias are based on a 75% majority vote. We considered "probably biased" and "confident biased" as biased and "confident not biased," "probably not biased," and "don't know" as not biased.
The types of stereotypes vary widely across the different categories of prejudice. While about a third of all biased tweets were classified as "hate" against the minority, the stereotypes in the tweets often matched common stereotypes about the minority. Asians were blamed for the Covid pandemic. Blacks were seen as inferior and associated with crime. Jews were seen as powerful and held collectively responsible for the actions of the State of Israel. Some tweets denied the Holocaust. Hispanics/Latines were portrayed as being in the country illegally and as "invaders," in addition to stereotypical accusations of being lazy, stupid, or having too many children. Muslims, on the other hand, were often collectively blamed for terrorism and violence, though often in conversations about Muslims in India.

Content:

This dataset contains 5880 tweets that cover a wide range of topics common in conversations about Asians, Blacks, Jews, Latines, and Muslims. 357 tweets (6.1 %) are labeled as biased and 5523 (93.9 %) are labeled as not biased. 1365 tweets (23.2 %) are labeled as calling out or denouncing bias. 1180 out of 5880 tweets (20.1 %) contain the keyword "Asians," 590 were posted in 2020 and 590 in 2021. 39 tweets (3.3 %) are biased against Asian people. 370 tweets (31,4 %) call out bias against Asians. 1160 out of 5880 tweets (19.7%) contain the keyword "Blacks," 578 were posted in 2020 and 582 in 2021. 101 tweets (8.7 %) are biased against Black people. 334 tweets (28.8 %) call out bias against Blacks. 1189 out of 5880 tweets (20.2 %) contain the keyword "Jews," 592 were posted in 2020, 451 in 2021, and ––as mentioned above––146 tweets from 2022. 83 tweets (7 %) are biased against Jewish people. 220 tweets (18.5 %) call out bias against Jews. 1169 out of 5880 tweets (19.9 %) contain the keyword "Latinos," 584 were posted in 2020 and 585 in 2021. 29 tweets (2.5 %) are biased against Latines. 181 tweets (15.5 %) call out bias against Latines. 1182 out of 5880 tweets (20.1 %) contain the keyword "Muslims," 593 were posted in 2020 and 589 in 2021. 105 tweets (8.9 %) are biased against Muslims. 260 tweets (22 %) call out bias against Muslims.

Europe's Jewish population in 1939 was around 9.5 million people, and it is estimated that six million of these were ultimately killed by 1945. The persecution of German Jews escalated during the interwar period, particularly after Hitler's ascent to power in 1933, and again after Kristallnacht in 1938. However, the scale of this increased drastically following the German invasions of Poland in 1939 and the USSR in 1941, when Germany annexed regions with some of the largest Jewish populations in Europe. Extermination Camps As part of the "Final Solution to the Jewish Question", the Nazi occupiers established six extermination camps in present-day Poland; these were Auschwitz-Birkenau, Belzec, Chelmno, Majdanek***, Sobibor, and Treblinka. Prisoners, mostly Jews, were transported from all over Europe to these camps. Upon arrival, the majority of victims were sent directly to purpose-built chambers or vans, where they were murdered with carbon monoxide or Zyklon B gas. A relatively small number of prisoners were also forced to dispose of the victims' bodies, which often included their own family members, friends, or persons known to them. Most of the deceased were incinerated, and many of the camp records were destroyed; this means that precise figures for the number of deaths in extermination camps will never be known. It has been estimated that at least 2.7 million Jews were murdered in these six camps; over two thirds of these were killed at Auschwitz or Treblinka. Einsatzgruppen After extermination camps, the most common method of murder was through mass shootings. The majority of these shootings were not carried out by regular soldiers, but specialized task forces known as "Einsatzgruppen". Each group was just a few hundred men each, but they were responsible for some of the largest individual acts of genocide in the war. The largest of these took place at Babi Yar, near Kyiv in 1941, where almost 35,000 victims were beaten, humiliated, and then shot over a two day period. The Einsatzgruppen were most active in the annexed Soviet territories (although additional regiments were active in Poland and the Balkans), and their ranks were often bolstered by local volunteers. It has been estimated that Einsatzgruppen were responsible for the genocide of more than two million people in fewer than six years.

Survey results are based on the responses from 5,847 self-identified Jewish respondents (aged 16 or over) living in one of eight EU Member States – Belgium, France, Germany, Hungary, Italy, Latvia, Sweden, and the United Kingdom for their opinions and perceptions on antisemitic trends and antisemitism as a problem in everyday life. The respondents were also asked to describe their personal experiences of antisemitic incidents, witnessing antisemitic incidents and worrying about being a victim of an antisemitic attack (affecting their personal safety, safety of children, or other family members and friends). The survey also provides data on whether the occurrence of antisemitic acts against the Jewish community, such as vandalism of Jewish sites or antisemitic messages in the broadcast media or in the internet, is considered to be a problem in their countries by the Jewish respondents.

The European Union Agency for Fundamental Rights (FRA) survey on Jewish people’s experiences and perceptions of discrimination, hate crime and antisemitism collected responses from 5,847 self-identified Jewish people in eight EU Member States – Belgium, France, Germany, Hungary, Italy, Latvia, Sweden and the United Kingdom. The survey provides for the first time comparable data on the perceived extent and nature of anti-Semitism across a number of EU Member States, whether it is manifested as hate crime, hate speech, discrimination or in any other form that undermines Jewish people’s feelings of safety and security. The survey asked respondents’ opinions about trends in anti-Semitism, anti-Semitism as a problem in everyday life, witnessing anti-Semitic incidents and worries about becoming a victim of an anti-Semitic attack (personal safety, safety of children, other family members and friends). The survey also provides data on the extent to which respondents consider anti-Semitic acts against the Jewish community, such as vandalism of Jewish sites or anti-Semitic messages in the broadcast media or on the internet, to be a problem in their countries. Furthermore, respondents were asked about their personal experiences of anti-Semitic incidents – harassment, violence and vandalism of property which the respondents felt took place because of them being Jewish. They could also describe their experiences of discrimination – in general and specifically linked to being Jewish – and their awareness of laws that exist to protect Jewish people from discrimination and hate crime. The survey data can also be explored online using the FRA's Data Explorer. Further information and publications can be found on the FRA website.
