What does CDR mean AP Human Geography?
Crude death rate Crude death rate (CDR) – The total number of deaths in a year for every 1,000 people alive in the society.
What is the crude death rate ap human geography?
Crude death rate (CDR)- total number of deaths in a year for every 1,000 people alive in the society. The annual number of deaths per 1,000 population. Natural increase rate (NIR)- the percentage by which a population grows in a year.

Infant mortality rate: (IMR) The annual number of deaths of infants under one year of age, compared with total live births. Its is expressed as the annual number of deaths among infants among infants per 1000 births rather than a percentage.
Why does Mexico have a lower CDR than the United States?
Mexico has a lower CDR than the U.S. because the U.S. has a higher number of elderly people, and Vietnam has a lower CDR than Sweden because Sweden has a higher number of elderly people.
What is crude population?
Birth rate, crude (per 1,000 people) Short definition. Crude birth rate indicates the number of live births per 1,000 midyear population. Long definition. Crude birth rate indicates the number of live births occurring during the year, per 1,000 population estimated at midyear.
What is DTM in AP Human Geography?
The demographic transition model is a tool demographers use to categorize countries' population growth rates and economic structures. The model analyzes birth rates, death rates, and total population trends in a society at a given point of time.
What is the crude birth rate CBR of the globe?
18.5 births per 1,000 people The average global birth rate was 18.5 births per 1,000 people in 2019, lower than in 2007 and 2012.
What is MMR in AP Human Geography?
Maternal mortality rate. -annual # of maternal deaths per 100,000 live births. -high MMR = less education for women (in terms of birth control and medicine)
How do CBR and CDR differ from each other?
CBR & CDR. The model is based on the change in crude birth rate (CBR) and crude death rate (CDR) over time. Each is expressed per thousand population. The CBR is determined by taking the number of births in one year in a country, dividing it by the country's population, and multiplying the number by 1,000.
Which region other than Sub Saharan Africa has the highest natural increase rate?
South Asia 2.2. 1: Which region other than sub-Saharan Africa appears to have the highest natural increase rate? South Asia appears to have the high natural increase rate outside of sub-Saharan Africa.
What is CBR and CDR?
PIP: Both the crude birthrate (CBR) and the crude death rate (CDR) represent a simple concept: the number of births or deaths which occur in a given year per 1000 population. They can also be used to calculate another fundamental measure, the rate of natural increase.
What is CBR in geography?
Crude birth rate indicates the number of live births occurring during the year, per 1,000 population estimated at midyear.
How are the DTM and ETM related?
The ETM describes causes of death in each stage of the DTM. The Epidemiological Transition Model focuses on why death rates are high or low.
What is Stage 3 of the DTM?
In Stage 3 of the Demographic Transition Model (DTM), death rates are low and birth rates decrease, usually as a result of improved economic conditions, an increase in women's status and education, and access to contraception.
What is crude death rate CDR?
Crude death rate indicates the number of deaths occurring during the year, per 1,000 population estimated at midyear. Subtracting the crude death rate from the crude birth rate provides the rate of natural increase, which is equal to the rate of population change in the absence of migration.
What does TFR mean AP Human Geo?
Total fertility rate Total fertility rate is an estimate of the average number of children born to each female in her childbearing years, whereas the rate of natural increase equals the birth rate minus the death rate. • B3. RNI measures population growth, whereas TFR measures fertility. •
What is CDR in population?
CRUDE DEATH RATE is the total number of deaths to residents in a specified geographic area (country, state, county, etc.) divided by the total population for the same geographic area (for a specified time period, usually a calendar year) and multiplied by 100,000.
Which region of the world appears to have the lowest CDR?
The Arabian Peninsula 2.2. 2: What region of the world appears to have the lowest CDR? The Arabian Peninsula appears to be the region with the lowest CDR.
What is Sub-Saharan Africa known for?
Sub-Saharan Africa, especially East Africa, is regarded by geneticists as being the birthplace of the human race. Mitochondrial Eve, from whom all humans alive are descended, is thought to have lived in present day Ethiopia or Tanzania.
What is crude death rate CDR )?
Crude death rate indicates the number of deaths occurring during the year, per 1,000 population estimated at midyear. Subtracting the crude death rate from the crude birth rate provides the rate of natural increase, which is equal to the rate of population change in the absence of migration.
What is ETM in geography?
ETM. Enhanced Thematic Mapper. Technology, Satellite, Astronomy.
What is DTM in AP human Geography?
The demographic transition model is a tool demographers use to categorize countries' population growth rates and economic structures. The model analyzes birth rates, death rates, and total population trends in a society at a given point of time.
What is a Stage 4 country?
A country in Stage 4 will have a much smaller base of young people (fewer children), but a much larger population of elderly (decreased CDR). A nation with a large youth population is more likely to be rural with high birthrates and possibly high death rates.
What countries are Stage 5?
In recent years a few countries, primarily in Eastern and Southern Europe, have reached a negative rate of natural increase as their death rates are higher than their birth rates. Possible examples of Stage 5 countries are Croatia, Estonia, Germany, Greece, Japan, Portugal and Ukraine.
What does GDI mean in AP Human Geography?
Gender-Related Development Index (GDI) Compares the level of development of women with that of both sexes. Human Development Index (HDI) Indicator of level of development for each country, constructed by the United Nations, combining income, literacy, education, and life expectancy.
What is CDR and CBR?
Abstract. PIP: Both the crude birthrate (CBR) and the crude death rate (CDR) represent a simple concept: the number of births or deaths which occur in a given year per 1000 population. They can also be used to calculate another fundamental measure, the rate of natural increase.
What is CBR CDR and Nir?
The most basic population indicators are the crude birth rate (CBR) and the crude death rate (CDR), reported in births (or deaths) per thousand people. These can be used to calculate the natural increase rate (equation 1). The NIR can be used to approximate calculating the doubling time (equation 2).
What is a high CDR?
The crude death rate measures the rate of deaths for every 1,000 people in a given population. Crude death rates of below 10 are considered low, while crude death rates above 20 per 1,000 are considered high.
