Why were the middle colonies well suited to single men looking to start a new life

The Middle Colonies were known for accepting people from different religions and cultures. There was religious freedom and most of the colonists were farmers.

Also the Middle Colonies had some industries like carpentry, four making, mines, ironworks and small-scale manufacturing.

This scenario was great for a single men to start a life, because people did not judge others on their culture of religion, also a single men could start a new life by being a farmers or working in a industry and creating a new life from there.

hello there!

the graphics that you have attached within the question, indicates that few people in bolivia work in industry according to its labor force.

however, the graphic that is on the right side of the picture shows the gdp sector in bolivia. this gross domestic product is a macroeconomic magnitude   that shows the monetary value of all finished goods and services within a country's borders in a specific time period. in this case, the graphic is showing the monetary value in each sector -agriculture, industry and services- of bolivia in 2012.

so, although the first graphic located at the left side indicates that not so many people work in industry, this is the second most important sector according to the gdp metrics because of the monetary value that impacts on its country. it does not need to be the most valuable one. if it makes an impact on the country's economy, it will be definitely crucial to it.
