Consider a country with nine million inhabitants and a stable population ie it just replaces itself. Now imagine a million arrivals with a slowly growing population, say 1% a year. After 50 years there will be 1.6 million of the immigrant group. If the growth rate is 2% a year, the figure will be 2.6 million descendants; at a 3% rate, it will be over 4.2 million, the original number having doubled after 25 years. Descendants of immigrants will then make up one-third of the total population.
People in charge of immigration policies need to be aware of this. Decisions made today will completely transform the society within half a century. What kind of a future to we want for our grandchildren?
