"The idea of ¿zero net migration' is gaining increasing currency. It has been assumed that if there is balance between the number of immigrants and emigrants, migration will have no impact on a country's population size. However, this article demonstrates that zero net migration is not necessarily the same as zero migration, and can result in a higher population than would have occurred without any migration at all." The examples of Germany and the United States are presented.
“零净移民”的概念越来越流行。人们一直认为，如果移民和移民出境的人数之间达到平衡，移民就不会对一个国家的人口规模产生影响。然而，本文表明，零净移民不一定等同于零移民，而且可能导致人口比完全没有任何移民的情况下还要多。文中列举了德国和美国的例子。
