Why were immigrants from southern and eastern europe more likely than immigrants from northern and western europe to settle in cities

After long establishing the central part of a relocation to America, European migration has mostly declined since 1960. The first critical European movement wave, spreading over the sixteenth to eighteenth hundreds of years, comprised the most of pilgrims from the British Isles pulled in by monetary chance and strict freedom. The fall of the Iron Curtain in the mid-1990s introduced the latest rush of European immigration, commanded by individuals from Eastern Europe and the previous Soviet Union.

Immigrants from Southern Europe were motivated by economic opportunities in the US and while the people immigrating from Eastern Europe left the continent due to religious persecutions.  

Explanation:

The "Southern and Eastern Europe" immigration was also motivated by political and social inequalities, bad economy, famines and they got contractual work employment from the recruitment agencies.

They worked in mines, steel mills, textile mills and many more. The "Northern and Western Europe" immigrated after the great depression.

Decline in agriculture and labor due to industry services such as motorization, chemical and others were some of the reasons that caused the great depression.
