If there were no immigrants, the population would be very different. Europe would be overly crowded, and probably unable to provide for its large population. The Americas would be nearly empty, populated only by Native Americans. Likewise, Australia would be sparsely populated only be native Australians.

Not particularly. Many of the immigrants from Ireland would not have been from Dublin, so would not have been familiar with it. Immigrants would go to places where they could live and survive and establish a new life. Places they would have went to were not like where they had come from. Even for those that were from Dublin, the cities they went to would have been different and others went to rural places and not cities.
