how can the size of the industrial/service sector and the agriculture employment rate indicate the level of industrialization?​

A larger industrial and service sector, and a larger number of people working outside of agriculture, can indicate a higher level of industrialization in the economy and vice versa. This means that the size of industrial service and the sector of agriculture employment rate indicates the level of industrialization because if the agriculture employment is higher than the industrial service it means that the country is not fully developed yet and therefore the level of industrialization is lower. But if the industrial service is higher than the agriculture employment that suggests or indicates that the country is developing or developed. For example in the United States the size of the industrial/service sector is much larger than it's agricultural employment and therefore this should suggest that country is much more industrialized or developed and the United States is. In comparison you take a developing country such as Chad and you can see that the agricultural employment is higher than the size of the industrial/service sector and in relation to this you can see that Chad must have a lower level of industrialization and in fact it does.
