The document discusses various "push factors" that caused thousands of Scots to emigrate from the Lowlands (eastern, southern, and central Scotland) during the 1800s-1900s. It describes poor working conditions in factories, shipyards, and mines including long hours, lack of safety protections, low pay, and seasonal unemployment. It also notes problems of overcrowded and unsanitary housing, diseases like tuberculosis and cholera due to these conditions, and lack of public support for healthcare or unemployment. These poverty factors pushed many Lowland Scots to seek new lives elsewhere through emigration to escape these hardships.
