Industrial Revolution to late 19th century

As new territories were opened and federal land sales were conducted, land had to be cleared and new homesteads established. Hundreds of thousands of immigrants annually came to the US and found jobs digging canals and building railroads. Almost all work during most of the 19th century was done by hand or with horses, mules, or oxen since there was very little mechanization. The workweek during most of the 19th century was 60 hours. Unemployment at times was between one and two percent.
