The theory of demographic transition is based on the idea that industrial development causes ________ and ___________ progress that affect population growth rates.

[I really have no clue what's the two missing words]

Will someone Please help me!!!!!!!!!!!!

Of course, I can help you with that! The theory of demographic transition suggests that industrial development causes changes in birth and death rates, which in turn influence population growth rates. To identify the two missing words related to progress in this context, we can analyze the theory's underlying concepts.

Demographic transition theory posits that as societies transition from a pre-industrial to an industrialized state, they experience several changes. In the pre-industrial phase, birth and death rates are high, resulting in slow population growth. However, with industrial development, certain societal changes occur.

The first change is a decline in death rates, primarily due to improvements in healthcare, sanitation, nutrition, and disease control. Essentially, industrialization leads to better living conditions and access to medical advancements, reducing mortality rates.

The second change is a decline in birth rates, which typically follows the decline in death rates. This can be attributed to numerous factors, including increased education and employment opportunities for women, urbanization, access to contraception, and a shift in societal norms regarding family size.

To summarize, based on the concept of demographic transition, industrial development causes a decline in death rates (leading to lower mortality) and a decline in birth rates (leading to lower fertility), thus affecting population growth rates.

Therefore, the two missing words related to progress in this context are "mortality" and "fertility." They are indicators of societal progress resulting from industrial development, influencing population growth rates.
