 York County was heavily tied to agriculture, with 93% of the work force involved in raising crops in 1850, while the rest of the United States averaged a 78% agricultural work force.In 1825 only three post offices operated in all of York County, at Yorkville, Blairsville and Hopewell, but by 1852 York District had 27.The county's first newspaper, "The Yorkville Pioneer", was established in 1823 (it ran for little more than a year), and was followed by several other attempts, until "The Yorkville Enquirer" was first published in 1855 (and which remains in publication today).
