What effect did riis’ book have on society?

First published in 1890, Jacob Riis's remarkable study of the horrendous living conditions of the poor in New York City had an immediate and extraordinary impact on society, inspiring reforms that affected the lives of millions of people.

Jacob Riis was very concerned with the treatment that immigrants received when they came to America. He did a lot of research and reporting of the conditions that immigrants faced such as work issues and living conditions. He wanted to improve the living conditions that these individuals had and address working issues.

The book was successful. Soon after its publication, The New York Times lauded its content, calling it a "powerful book".

Because of this awakening caused by Riis' efforts, many reforms were quickly compiled to improve conditions for the working poor. In 1894, the Tenement House Committee was established. In 1895, they published the New York Tenement House Act, which outlawed rear tenements and also was the first official document to supplement a written description of tenement housing with photographs.

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.
