Similarities and differences between the eras:

Similarities:

• All three eras have seen a significant increase in mobility, as people have moved from rural areas to cities and from one country to another.
• The main reasons for people to move have remained the same throughout history: to find work, to get married, or to escape war or famine.
• The development of new transportation technologies has played a major role in increasing mobility. For example, the invention of the railroad and the automobile made it easier and faster for people to travel long distances.

Differences:

• The scale of mobility has increased over time. In the pre-industrial era, most people lived and died in the same village or town. In the industrial era, people began to move to cities from rural areas. In the post-industrial era, people are moving between countries in search of work, education, and lifestyle reasons.
• The types of people who are mobile have also changed over time. In the pre-industrial era, only wealthy people could afford to travel long distances. In the industrial era, working-class people also began to move in search of work. In the post-industrial era, people from all social classes are more likely to be mobile.
• The motivations for moving have also changed over time. In the pre-industrial era, people were more likely to move for economic reasons (to find work or escape famine). In the industrial era, people were also drawn to cities by the promise of a better life. In the post-industrial era, people are more likely to move for lifestyle reasons (to be closer to family and friends or to live in a different country).

Conclusion:

The key eras of popular mobility have seen a significant increase in the scale, types, and motivations for people to move. The development of new transportation technologies has played a major role in this increase in mobility.
