Annual net immigration into Europe is projected to increase steadily from current levels for another 20 years. This year, just over 1 million immigrants will arrive in the Europe, according to Eurostat, the statistical agency of the E.U. That figure will reach an apex of nearly 1.5 million in 2036, the agency projects.

If current trends hold, immigration to Europe will not subside below its current level until 2069. The continent will have seen net immigration of 77 million people in that time. The figure includes immigrants to the 28 members of the E.U. as well as Iceland, Norway and Switzerland.

By 2080, these migrants and their progeny will have increased the population of the E.U. by 121 million, relative to what the continent’s population would be then without any immigration. The result will be a Europe that is substantially more diverse than it is today.
