The estimated population of unauthorized immigrants in the U.S. stands at around ** million people. Although the number has stabilized, the United States has seen a spike in migrant encounters in the last few years, with over * million cases registered by the U.S. Border Patrol in 2023. This is a slight decrease from the previous year, when there were over *** million cases registered. Due to its proximity and shared border, Mexico remains the leading country of origin for most undocumented immigrants in the U.S., with California and Texas being home to the majority.
Immigration and political division
Despite the majority of the population having immigrant roots, the topic of immigration in the U.S. remains one of the country’s longest-standing political debates. Support among Republicans for restrictive immigration has grown alongside Democratic support for open immigration. This growing divide has deepened the polarization between the two major political parties, stifling constructive dialogue and impeding meaningful reform efforts and as a result, has led to dissatisfaction from all sides. In addition to general immigration policy, feelings toward illegal immigration in the U.S. also vary widely. For some, it's seen as a significant threat to national security, cultural identity, and economic stability. This perspective often aligns with support for stringent measures like Trump's proposed border wall and increased enforcement efforts. On the other hand, there are those who are more sympathetic toward undocumented immigrants, as demonstrated by support for the Deferred Action for Childhood Arrivals (DACA) program.

Germany has long been involved with international asylum applications, especially in recent years. The most applications came from Syrian asylum seekers. These was followed by applications from Afghanistan and Turkey. Germany as a refuge choice Statistics on the number of asylum applicants in Germany are recorded by the BAMF, or the Federal Office for Migration and Refugees (Bundesamt für Migration und Flüchtlinge). The coronavirus (COVID-19) pandemic has decreased refugee numbers in Europe, with travel bans across modes of transport and borders being closed. As the restrictions begin to lift, migration is beginning again. 2023 saw the highest number of applications for asylum since 2016. However, in 2024, numbers have decreased significanly again. Support for refugees remains a present issue, fraught with tension, legal complications and surrounded by constant debate with many believing that not enough is done to support them. Asylum decisions Not all asylum applications in Germany get accepted, due to various circumstances. Besides rejection, decisions regarding asylum may involve granting a legal status as a refugee, a grant of subsidiary protection or determining a deportation ban.
Between 1941 and early 1945, over 1.3 million people were deported to the Auschwitz concentration camp complex; approximately 1.1 million of these deportees were Jewish, and one million Jews were murdered. Auschwitz was the largest of six extermination camps constructed by the Nazi regime in Poland, as part of their "Final Solution to the Jewish Question", which sought to exterminate Europe's Jewish population.
The Holocaust in Hungary Of the 1.1 million Jews sent to Auschwitz, the most common country of origin was Hungary. Hungary had a sizeable Jewish population of around 445,000 people in 1930, but Hungary's territory grew significantly after it annexed parts of Slovakia, Romania, Ukraine, and Yugoslavia in the late-1930s, and the total Jewish population (including Christians with Jewish heritage) in the 1941 census was approximately 825,000. Compared to the Germans, Hungary's treatment of the Jews throughout the war had been much less restrictive, and its prime minister opposed deportations to concentration camps. German invasion and increasing number of deportations This changed, however, in March 1944; as the Axis forces were being pushed west out of Soviet territory; Germany then invaded Hungary to prevent them from negotiating a peace with the Allies. Thereafter, a puppet government was installed and authorities, under the leadership of Adolf Eichmann, began to round up and deport Jews to Poland. While the Nazi extermination of Jews began on a large scale in 1941, the majority of Hungary's victims were deported and murdered over an eight week period, between May and July 1944. 430,000 Jews were deported from Hungary to Auschwitz in this time; it is estimated that around 20 percent of these were selected for labor, and the remaining 80 percent were sent directly to the gas chambers. Arrivals from Hungary were so rapid that the crematoriums could not keep up with the rate of murder, and additional mass graves had to be dug while the number of trains was reduced. Eventually, as the Axis position deteriorated, Hungarian authorities ceased deportations under mounting pressure from the Allies in early July. Exact figures for Hungary's death toll in the Holocaust remain elusive, although it is estimated that over 560,000 Jews were killed from within Hungary's wartime borders (270,000 from pre-war territories), with 434,000 of these deaths taking place between May and July 1944, the majority of which at Auschwitz.
