By the early 1900’s Liverpool’s population had grown to almost one million people  with a significant immigration from Ireland. Due to the potato famine 300 000 Irish people arrived in Liverpool in the twelve months following 1847 – most of whom then emigrated to the east coast of North America.
New York’s population during that time (1950’s) was about 100 000 more than Liverpool’s, however, it continued to grow until the 1950’s where it peaked at just under eight million inhabitants . Although New York’s population has remained consistent Liverpool’s shrunk dramatically. Liverpool now has almost half the population that it had a century ago.
