How is the growth and migration of the population in the late 19th century – early 20th century related to the industrial development of countries, with changes in their political life? What is the significance of emigrants in building an industrial society?

The emergence of the industrial model influenced the nature of relations between people. In economically developed regions, there were trends towards an increase in production volumes. This required the so-called “blue collars”. For this reason, the emigration inflow to the industrialized states has increased. Another reason was that these areas offered salaries in blue-collar jobs much higher than in their usual habitats. After the market was oversaturated with labor, countries began to introduce measures to limit them.
