What was a major push factor that increased immigration to the United States between 1830 and 1850?

A push factor is a condition that encourages people to leave their home country. Between 1830 and 1850, economic hardship—including poverty, unemployment, and famine in parts of Europe—pushed many people to immigrate to the United States. Factory employment and abundant land were attractions in the United States, so they were pull factors rather than push factors.
