What were the pull-push factors for European emigration to America?

Pull factors:

America had a lot of undeveloped land that European farmers could easily obtain, and work.

America had a developing economy, where industry was growing very fast, and demand for workers was accordingly high.

America had a political structure that protected civil rights such as freedom of religion, freedom of speech, and freedom of assembly.

Push factors:

Many areas in Europe were overpopulated in regards to the productivity of the land, and this caused frequent famines, land conflicts, and political instability.

Many areas in Europe had tyrannical governments were civil liberties were not respected.

Europe had several religious denominations that were persecuted all over the land, and this prompted their members to emigrate to the United States where they would enjoy the freedom to practice their faith.
