All Flashcards
What is Crude Birth Rate (CBR)?
The number of births per 1,000 individuals in a population per year.
What is Crude Death Rate (CDR)?
The number of deaths per 1,000 individuals in a population per year.
Define Demographic Transition Model (DTM).
A model that describes population change over time as a country develops.
What characterizes Stage 1 of the DTM?
High CBR and high CDR, resulting in low population growth.
What characterizes Stage 2 of the DTM?
High CBR and declining CDR, resulting in high population growth.
What characterizes Stage 3 of the DTM?
Declining CBR and declining CDR, resulting in slowing population growth.
What characterizes Stage 4 of the DTM?
Low CBR and low CDR, resulting in low or zero population growth.
What characterizes Stage 5 of the DTM?
Low CDR and rising CBR, resulting in a stable or slowly increasing growth rate.
What is meant by 'Pre-industrial' stage in relation to DTM?
High birth and death rates, limited resources, and high infant mortality.
What is meant by 'Transitional' stage in relation to DTM?
Improved health care and sanitation, leading to a drop in death rates. Birth rates remain high, causing a population boom.
What is meant by 'Industrial' stage in relation to DTM?
Birth rates start to decline due to education and family planning. Population growth slows.
What is meant by 'Post-industrial' stage in relation to DTM?
Low birth and death rates. Population stabilizes or declines.
What is Crude Birth Rate (CBR)?
The number of births per 1,000 individuals in a population per year.
What is Crude Death Rate (CDR)?
The number of deaths per 1,000 individuals in a population per year.
Define Demographic Transition Model (DTM).
A model that describes population change over time as a country develops.
What factors cause high birth rates in Stage 1 of the DTM?
Lack of family planning, high infant mortality, need for farm labor.
Why do death rates decline in Stage 2 of the DTM?
Improved healthcare, sanitation, and food availability.
What leads to declining birth rates in Stage 3 of the DTM?
Increased education, family planning, and urbanization.
What characterizes population growth in Stage 4 of the DTM?
Low birth rates, low death rates, and stable or declining population.
What is the main characteristic of Stage 5 of the DTM?
Low CDR, rising CBR, and a stable or slowly increasing growth rate.
How does industrialization affect the DTM?
Leads to decreased death rates in Stage 2 and decreased birth rates in Stage 3.
How does the DTM relate to resource management?
Understanding the DTM helps predict population trends and plan for resource allocation.
How is the DTM connected to urbanization?
Urbanization often leads to lower birth rates as seen in Stage 3.
What is the relationship between development and the DTM?
Countries move through the DTM as they develop, reflecting societal changes.
What are some limitations of the DTM?
It is a model, and real-world scenarios can be more complex and vary from the model's predictions.
