This chart is worthless. It ranks countries based on the % increase in population if all who wanted to move there actually did. Of course the developed countries with the smallest populations rank at the top. Singapore has a total population of 4.5m. If 11.7m people want to move there, the population goes up 260%. If the same 11.7m people want to move to the US (304m pop), the population goes up 3.8%. In reality, the number of people who want to come to the US is 182m people, or over 15x the number who want to move to Singapore.
