Over 1 million migrants and refugees have come to Europe … by sea … in 2015 alone. That's a lot.
According to the U.N. High Commissioner for Refugees, most came through Greece — about 850,000. The next highest number of refugee arrivals — 152,000 — were in Italy. Spain and Malta rounded off the rest with a little under 3,700 migrants and refugees entering those two countries.
About 3,700 went missing or died in 2015.

And as the conflicts in these refugees' countries have become worse, fewer have been granted asylum.

Other barriers are ideological. More and more people fear refugees may be extremist infiltrators.
"A complete and total shutdown of Muslims entering the United States," Donald Trump said at a campaign rally.
Though 2016 could be a better year for refugees. While Europe was initially caught off guard by the huge influx of migrants and refugees, the UNHCR says European nations are starting to coordinate their response.
