Which term refers to the actual level of childbearing for an individual or a population?

Q: What do you call the model describing changing levels of fertility and mortality and hence natural increase over time?

This usually refers to the Demographic Transition Model but may be used to simply mean changes in population numbers and structure over time. Crude Birth Rate (CBR)

Q: What is replacement fertility in births per woman quizlet?

Replacement level fertility is the total fertility rate—the average number of children born per woman—at which a population exactly replaces itself from one generation to the next, without migration. This rate is roughly 2.1 children per woman for most countries, although it may modestly vary with mortality rates.

The total fertility rate in a specific year is defined as the total number of children that would be born to each woman if she were to live to the end of her child-bearing years and give birth to children in alignment with the prevailing age-specific fertility rates. It is calculated by totalling the age-specific fertility rates as defined over five-year intervals. Assuming no net migration and unchanged mortality, a total fertility rate of 2.1 children per woman ensures a broadly stable population. Together with mortality and migration, fertility is an element of population growth, reflecting both the causes and effects of economic and social developments. The reasons for the dramatic decline in birth rates during the past few decades include postponed family formation and child-bearing and a decrease in desired family sizes. This indicator is measured in children per woman.

Population and Urbanization

Question	Answer

Crude birth rate	the number of live births per 1,000 people in a population in a given year
Crude death rate	the number of deaths per 1,000 people in a population in a given year
Demographic transition	the process by which some societies have moved from high birth rates and death rates to relatively low birth rates and death rates as a result of technological development
Demography	a subfield of sociology that examines population size, composition, and distribution
Fecundity	the potential number of children who could be born if every woman reproduced at her maximum biological capacity
Fertility	the actual level of childbearing for an individual or a population
Gentrification	the process by which members of the middle and upper middle classes, especially whites, move into a central-city area and renovate existing properties
Human ecology	the study of the relationship between people and their physical environment
Invasion	the process by which a new category of people or type of land use arrives in an area previously occupied by another group or land use
Metropolis	one or more central cities and their surrounding suburbs that dominate the economic and cultural life of a region
Migration	the movement of people from one geographic area to another for the purpose of changing residency
Mortality	the incidence of death in a population
Population composition	the biological and social characteristics of a population, including age, sex, race, marital status, education, occupation, income, and size of household
Population pyramid	a graphic representation of the distribution of a population by sex and age
Sex ratio	a term used by demographers to denote the number of males for every hundred females in a given population
Succession	the process by which a new category of people or type of land use gradually predominates in an area formerly dominated by another group or activity
Zero population growth	the point at which no population increase occurs from year to year

What do you call the model describing changing levels of fertility and mortality and hence natural increase over time?

This usually refers to the "Demographic Transition Model" but may be used to simply mean changes in population numbers and structure over time. Crude Birth Rate (CBR)

What is replacement fertility in births per woman quizlet?

Replacement level fertility" is the total fertility rate—the average number of children born per woman—at which a population exactly replaces itself from one generation to the next, without migration. This rate is roughly 2.1 children per woman for most countries, although it may modestly vary with mortality rates.

Is the potential number of children that could be born if every woman reproduced as often as biology allowed?

Fecundity is the potential number of children that could be born if every woman reproduced as often as biology allowed. Obvi- ously, fertility rates are much lower than fecundity rates. The highest realistic fecundity rate you could expect from a society would be about fifteen births per woman.

Which of the following is not one of the preconditions that must be present for a city to develop as described by sociologist Gideon Sjoberg?

According to the sociologist Gideon Sjoberg, three preconditions must be present in order for a city to develop. All of the following were preconditions identified EXCEPT: a wall built around the city for protection.
