But generally speaking, a natural increase in population is beneficial for social stability because of similarities or race and culture, while "a large population of foreign migrants is often something that can't be helped," says Chien Tai-lang, whose bureau is in charge of both population and immigration. Add to this that Taiwan's area is limited, and from either environmental or social perspectives, cannot absorb too many foreign immigrants.
但一般而言，自然增加的人口，由於種族、文化同質性高，對社會的安定有好處，「大量的外來移動人口往往是不得已的」，同時掌管人口與移民政策的內政部戶政司長簡太郎說，再加上台灣面積有限，不論由環境或社會角度來看，都不太可能引進太多外來人口。
