By 1860, manufacturing in the north outnumbered that in the south by what ratio?

During the American Civil War, the south Confederate States is way below the northern Union in terms of economy. The North has an established industrial and agricultural base with lots of transport infrastructure. Meanwhile, the South has mainly agrarian-based economy with little manufacturing, and it only has the Mississippi river as its main waterway. Manufacturing is crucial for production of goods and arms, and the North has 5 times the number of factories as the South (5:1).

explanation:

angel island immigration station was an immigration station located in san francisco bay which worked from 1910 to 1940. the majority of immigrants that got there were from the asian hemisphere, specifically from china, japan, russia, and south asia, being china the country from where more people arrived.

the number of foreigners arriving at it took the attention of americans who feared the new arrivals would take their jobs. the work opportunities were not abundant due to the economic comedown of 1870 and the asians, as newcomers, were willing to work for cheaper wages. soon they started to be seen as a threat, which led to an increased discrimination against the chinese - the biggest ethnicity arrived at this station until 1915 when japanese immigrants outnumbered them - being considered as unsuitable americans hence their looks and social situation.

at the station, the immigrant's detention may vary depending on how long the interrogation process took: it could be weeks, months, or even years.

finally, in 1940 an explosion destroyed administration building located on the island, so the united states government decided to stop the process.
