Unit 2: Popualtion And Health/Migration Flashcards
Ecumene
The portion of earths surface occupied by permanent human settlement
Arithmetic Density
The total number of people divided by the total land area
Physiological Density
The number of people per unit of area of arable land, which is land suitable for agriculture
Agricultural Density
The ratio of the number of farmers to the total amount of land suitable for agriculture
Crude Birth Rate (CBR)
The total number of live births in a year for everyone thousand people live in a society
Crude Death Rate (CDR)
The total number of deaths in a year for every thousand people alive in society
Natural Increase Rate (NIR)
The percentage of growth of the population in a year, computed as: CBR minus CDR
Doubling Time
The number of years needed to double a population, assuming a constant rate of natural increase
Total Fertility Rate (TFR)
The average number of children a woman will have throughout her childbearing years
Population Pyramid
A bar graph that represents the distribution of population by age and sex
Dependency Ratio
The number of people under age 15 and over age 64 compared to the number of people active in the labor force
Sex Ratio
The number of males per 100 females in the population
Demographic Transition
A process of change in a societies population from high CBR and CDR/ low NIR to low CBR and CDR, low NIR, and high total population
Industrial Revolution
A series of improvements in industrial technology that transformed the process of manufacturing goods
Medical Revolution
Medical technology invented in Europe and North America that has diffused to the poor countries in Latin America, Asia, and Africa. Improved medical practices have limited many causes of death in poor countries and enabled longer lives
Zero Population Growth (ZPG)
The Declan of the total fertility rate to the point where the natural increase rate is zero
Epidemiological Transition
Distinctive causes of death in each stage of the demographic transition
Stages:
1.Pestilence and Famine (high CDR)
2. Receding Pandemics (rapid decline of CDR)
3. Degenerative diseases (moderately decline CDR)
4. Delayed degenerative diseases (low, but increasing CDR)
5. Possible: evolution/poverty
Pandemic
Disease that occurs over a wide geographic area and affects a very hi portion of population
Infant Mortality Rate (IMR)
The total number of dots any are among infants under one for every 1000 live births in a society
Life Expectancy
The average number of years an individual can be expected to live, given current social, economic, and medical conditions. Life expectancy at birth is the average number of years a newborn infant can expect to live
Migration Transition
A change in the migration pattern in a society that results from industrialization, population growth, and other social and economic changes to also produce the DTM.
Stages:
1. Low NIR/high CBR/ high CDR– Search for food
2. High NIR/high CBR/declining CDR– International emigration/rural to urban
3. Declining NIR/rapid decline CBR/decreasing CDR– high international immigration/cities to suburbs
4. Low NIR/low CBR/low CDR– Same as 3^^
International Immigration

Voluntary Migration
Permanent movement undertaken by choice
Forced Migration
