Population and Health Human Geography Flashcards
Where is the world’s population distributed?
Asia, Africa, Europe and the Americas
Define Population
The collection of human beings in a certain place
Define Demography
A social science which entails the statistical study of human populations
Rate of Natural Increase (RNI)
The percentage of a country or region’s growth rate
Total Fertility Rate
A synthetic rate that expresses the fertility of a country or region; commonly understood as the average number of children a woman would give birth to during her reproductive years
Young and Old Populations
The proportion of young persons (i.e., those under 15 years of age) compared to the proportion of persons over 65 years of age; graphically illustrated by population pyramids, which also reflect sex differences of the population.
Population Pyramids
The visual representation of a nation’s population representing age and gender.
Life Expectancy
The average number of years a person is expected to live from birth; influenced by health services, nutrition, and sanitation; used as an indicator of social development
The Demographic Transition
A conceptual model that tracks changes in birth and death rates for a country or region over time
Why is global population increasing?
Birth Rates are bigger than Death Rates
To identify and discuss the 3 components of measuring population change
Crude Birth Rates(CBR): The number of live birth rates a year for every 1000 people
Crude Death Rates(BDR): The number of deaths a year for every 1000 people
Natural Increases Rates(NIR): The Percentage a population grows in a year
Explain the progression of population change over time
Population is affected by CDR and CBR
When those are decreased population goes up since birth and death rates go down
To identify the impact of TFR and IMR on population statistics
TFR is the average amount of children a woman has
If its high (like 5) it can double the population,(bad boomers)
if TFR goes down IMR(infant mortality rate) will go down with it
