DEMOGRAPHY / RATES, RATIO, VITAL STATISTICS Flashcards
is the statistical study of the human population
DEMOGRAPHY
Instead of a census, demographic information can still be collected from a sample of a given population
SAMPLE SURVEY
refers to the movement of persons from an origin place to a destination place across some pre-defined, political boundary
MIGRATION
the number of live births per woman completing her reproductive life, if her childbearing at each age reflected current age-specific fertility rates
TOTAL FERTILITY RATE
one that has had constant crude birth and death rates for such long time that the percentage of people in every age class remains constant, or equivalently, the population pyramid has an unchanging structure
STABLE POPULATION
the number of daughters who would be born to a woman completing her reproductive life at current age-specific fertility rates
GROSS REPRODUCTION RATE
study of the character, number, and distribution of living organisms residing in or migrating through particular places
POPULATION
TRUE OR FALSE
A stable population does not necessarily remain fixed in size, it can be expanding or shrinking
TRUE
is simply the difference between the number of births and the number of death occurring in a population in a specified period of time
NATURAL INCREASE
-measures the proportion of the population which exhibits a particular disease at a particular time
-deals with total (old and new) number of cases
PREVALENCE RATE
is done when people are assigned to the place where they usually live regardless of where they are at the time of census
DE JURE
-is a ratio involving a time period
-the count or measurement is observed over a period and then divided by its base or population of observation
RATE
is the study of the attributes of and changes in the aggregate number of people residing in particular communities around the world and their causes
HUMAN DEMOGRAPHY
measures the risk of dying in the first four weeks of life of the infant (newborn)
NEONATAL MORTALITY RATE
also called a proportion is the quotient of two numbers
RATIO
the annual number of live births per 1,000 people
CRUDE BIRTH RATE
measures the risk of dying due to the process of pregnancy, childbirth and puerperium.
MATERNAL MORTALITY RATE
is the difference between the CBR and the CDR occurring in a population in a specified period of time
RATE OF NATURAL INCREASE
-the annual number of deaths of children less than 1 year old per 1,000 live births
-measures the risk of dying due to infancy (under 1 year of age)
INFANT MORTALITY RATE
study of the causes, consequences, and measurement of processes affecting death to members of the population
MORTALITY
measures the risk of dying before birth
FETAL DEATH RATE
is done when the people are assigned to the place where they are physically present at the time of the census regardless of their usual place of residence
DE FACTO
measures the loss of life in later pregnancy and early pregnancy
PERI-NATAL MORTALITY RATE
a woman’s childbearing potential
FECUNDITY
-measures the frequency of occurrence of the phenomenon during a given period of time
-deals only with NEW cases
INCIDENCE RATE
is the expected number of daughters, per newborn prospective mother, who may or may not survive to and through the ages of childbearing
NET REPRODUCTION RATIO
one that is both stable and unchanging in size (the difference between crude birth rate and crude death rate is zero)
STATIONARY POPULATION
TRUE OR FALSE
censuses typically occur only every 10 years or so and thus are not usually the best source of data on births and deaths
TRUE
the average number of children a woman must have in order to replace herself with a daughter in the next generation.
REPLACEMENT LEVEL FERTILITY
Population can change through THREE processes:
FERTILITY, MORTALITY, MIGRATION
the annual number of live births per 1,000 women in particular age groups (usually age 15-19, 20-24 etc.)
AGE-SPECIFIC FERTILITY RATE
TRUE OR FALSE
Since the census asks for a complete enumeration of the population, it is usually a VERY EXPENSIVE undertaking
TRUE
involves the number of children that women have
FERTILITY
the annual number of deaths per 1,000 people
CRUDE DEATH RATE
the annual number of live births per 1,000 women of childbearing age (often taken to be from 15 to 49 years old, but sometimes from 15 to 44)
GENERAL FERTILITY RATE
A ______ is the other common direct method of collecting demographic data
CENSUS
is the number of years which an individual at a given age could expect to live at present mortality levels
LIFE EXPECTANCY
