How did the farm population in the united states change between 1950 and today?

The numbers dropped drastically. There are far fewer farms than there were before. This happened because the US started dealing with services more than production of goods and/or produce. People moved from farms to suburbs and cities and the farming business got reduced.

Explanation:

World War 1 began by  Sarajevo, Bosnia, where Archduke Franz Ferdinand—heir to the Austro-Hungarian Empire was shot to death along with his wife, Sophie, by the Serbian nationalist Gavrilo Princip on June 28, 1914. This was an assination that happened to be the very first thing to make the first world war happen.
