chapter 4 Flashcards
(31 cards)
Whole number of inhabitants occupying an area and continually being modified by increases (births and immigrations) and losses (deaths and emigrations).
Population
Population that is both stable and unchanging size. (Carey et al.,
2018). The difference between crude birth rate and crude death rate is zero.
Population that has a constant crude birth & death rate for such a
long period. (Glossary of Demographic Terms, n.d.). The percentage of people in every age class is constant
Stable population
Population that is both stable and unchanging size. (Carey et al.,
2018). The difference between crude birth rate and crude death rate is zero.
Stationary population
Increase in the number of individuals in a population.
POPULATION GROWTH
biological potential for reproduction. Biological ability to reproduce.
Fecundity
the actual level of achieved reproduction. Actual number of births.
Fertility
biological potential for reproduction. Biological ability to reproduce.
Fecundity
Some women become widowed and do not remarry,
unrestricted maximum growth of that population
the highest possible vital index of a species (highest birth rate, low mortality rate).
BIOTIC POTENTIAL
- upper limit to biotic potential in the
absence of mortality.
Reproductive potential (potential natality)
Some women become widowed and do not remarry,
unrestricted maximum growth of that population
the highest possible vital index of a species (highest birth rate, low mortality rate).
BIOTIC POTENTIAL
- Opposite of mortality
Survival potential
ability to get and use food for growth and energy.
Nutritive potential -
the ability to protect itself against the environment to survive
and reproduce.
Protective potential
Demo, and Graphy meaning
the people, (writing, description, or measurement)
Statistical study of populations, especially human beings.
The quantifiable characteristics of a given population
Study of demographic change requires birth, migration and death
Demography
the best method for estimating the number of births & deaths
Registry statistics -
Common direct method, conducted by a national government to enumerate
every person in a country
Census
2 types of demography
Direct and indirect
Quantitative study of the human population in the past
Historical Demography
requires asking women how many of their sisters died/had children
& at what age.
Sister Method
asking about siblings, parents, and children is necessary in
historical demography
Other Indirect Method
