What are some push/pull factors for cowboys/ranchers?

Answer

A variety of factors contributed to Westward Expansion, including population growth and economic opportunities on what was presented to be available land.

Explanation:

During the 19th Century, more than 1.6 million square kilometers (a million square miles) of land west of the Mississippi River was acquired by the United States federal government. This led to a widespread migration west, referred to as Westward Expansion.Throughout most of the 19th century, there were two main ways to make money west of the Mississippi River: through gold and silver prospecting, and through developing land for agriculture, industry, or urban growth. These two activities often supported each other.
