Study Notes
Population Studies
- Population Density: The number of individuals per unit area or volume, often expressed as people per square kilometer or organisms per square meter.
Demography
- Demography: The study of human populations, including their size, structure, and distribution, as well as factors that affect them, such as fertility, mortality, and migration.
Life Tables
-
Components of a Life Table: A statistical tool used to analyze mortality rates, comprising:
- Cohort life table: follows a single cohort (group of individuals) over time.
- Period life table: based on mortality rates for a specific period.
- Stationary life table: assumes a stable population.
Population Growth
-
Intrinsic Rate of Increase: The rate at which a population grows or declines due to factors like birth and death rates.
- Influenced by:
- Fecundity (reproductive rate)
- Mortality rate
- Migration
- Influenced by:
Population Dynamics
- Population Dynamics: The study of changes in population size, structure, and distribution over time, considering factors like reproduction, mortality, migration, and environmental pressures.
