Well, 1810 would be very different from 1890; let's settle on the post civil-war period (1865-1900). If we restrict the question to this time frame, we still find that the majority of workers were participants in an agrarian economy; they were mainly farmers, herders, cowboys, ranchers, and such. But at this point, towns and cities were becoming widely established, so there were many other occupations: miners, saloon owners, doctors, lawyers, bankers, railroad workers, loggers, trappers, builders (mainly carpenters), tailors, blacksmiths, etc., but all of these still essentially supported the agrarian economy. The major shift to a manufacturing economy can be said to have begun around 1875-1880, though farming is still a significant industry in many parts of the western states; i.e., California's Central Valley.
Farmers, Hunters, Explorers, Frontiersman, agriculture, Raw materials were made and shipped to northern factories.
Farming, the land was cheap and the soil was rich enough so you can grow good crops and make a lot of money.
Industries moved west in the 1800s.
The American pioneers migrated west in the late 1800s. They intended to settle new territories that had not already been developed by Europeans or Americans.
The population of the cities in the West decreased as unsuccessful miners moved back to the East

Civilization crept across the United States of America during the 1800s, because people moved farther and farther west, looking for homesteads.
Many people died due to the famine. Most people moved to the West (mostly California) to look for jobs.
Because the gold rush in California was going on and everybody wanted some gold, also there wasn't many people in the west and the east and south was crowded so people moved to the west.
