The document presents information about stable and stationary populations. It defines a stable population as one with constant birth and death rates and no migration, resulting in a constant growth rate. A stationary population is a type of stable population where the birth and death rates are exactly equal, resulting in a zero growth rate and no change in population size. The document provides some basic definitions of population and explains that while all stationary populations are considered stable due to their consistent parameters, not all stable populations are stationary if the birth and death rates are not precisely equal.

items,for example,balls in an urn.
Demographers use the term to denote the collection of
persons alive at a specific point in time who meet certain
criteria.
Legal/Illegal residents
Criteria includes Race/Ethnicity
Sex

4. STABLE POPULATION
StablePopulation Constant Birth
Constant Death
Growth Rate
Constant
No Migration

5. STATIONARY POPULATION
StationaryPopulation Constant Birth
Constant Death
Zero Growth Rate
BIRTH=DEATH
No Migration

6. NOT ALL STABLE POPULATION ARE
STATIONARY BUT STATIONARY
POPULATION ALWAYS TERMED AS STABLE
POPULATION.
HOW?????????

7. Stationary Population is a type of Stable Population
