Q

What is the demographic equation?

Study These Flashcards
A

P2 = P1 + B − D + IM − OM

P2 is population at time 2
P1 is population at beginning date
B is the number of births
D is the number of deaths
IM is the number of in-migrants
OM the number of out-migrants

24
Q

Use the dem eq to solve:
What is the total current population (P2) if:
P1 = 1,500,000; B = 300,000; D = 100,000; IM = 150,000; OM = 50,000

25
the scientific study of population, with particular emphasis on quantitative aspects
demography
26
demography answers specific questions about ___
population
27
a high _____ rate generally indicates less developed country
birth
28
a high ____ rate can indicate a developing country (countries with a low rate are more developed: USA, CHINA, etc)
fertility
29
common indicator of development stage, health care access, economy
infant mortality rate
30
What causes rapid growth population?
Large youth population and fewer elderly. High birth rates drive this, leading to a future boost in the workforce but also increasing dependency.
31
What causes decline in population?
Higher numbers in the 65+ age group, lower birth rates, and fewer young people. This can stra
32
What causes steady population?
Balanced age distribution with steady birth and death rates. This creates stability in the workforce, dependents, and social services.
33
Average ratio worldwide: _____ females to be born for every 100 males. But evens out b/c: more ___ die before age 5
95 males
34
relationship between births and deaths in positive, stable, and negative population growth
pos - more births than deaths stable - replacement level (roughly same number of births as deaths) neg - more deaths than births
35
what influences total growth of a population?
net migration
36
Nigeria projected to surpass United States population by
2050
37
1. What year did population reach 1 billion? 2. How long to reach 7 billion? 3. Which regions are growing fastest (more or less developed?)
1. 1800s (1804) 2. 200 (207) 3. Less developed; developing
38
relationship between the number of inhabitants and the area they occupy
population density
39
Permanently inhabited areas of Earth
Ecumene
40
Portion of Earth’s surface that is uninhabited or only temporarily or intermittently inhabited
Nonecumene
41
35% to 40% all land surface make up ecumene or nonecumene portion of earth?
nonecumene
42
Latitudinal Distribution | Where is % of total world population higher? (below, on, or above equator?)
Above the equator
43
What are physical, environmental, and geographic reasons for sparse population clusters?
Cold Mountains Dry Lands Wet Lands
44
Nodes Surrounding Nonecumene; Ex: Taklamakan Desert | Why are there dense population centers surrounding?
1.Water Sources: Availability of rivers like the Tarim River for irrigation. 2.Trade Routes: Historical significance as part of the Silk Road, facilitating trade. 3.Economic Opportunities: Presence of mineral resources and agricultural potential. 4.Cultural Significance: Rich cultural history with diverse ethnic communities. 5.Transportation Links: Proximity to major routes connecting to larger cities and markets.
45
How can ecumenes be extended?
Irrigation, terracing
46
The number of people per unit area of land
Crude Density (Arithmetic)
47
The number of people per unit area of agricultural (arable) land
Physiological Density
48
Physiological density is more useful than _____ because it estimates how many people can be supported by ______ land
crude; arable
49
What is a high and low physiological density?
high - over 1000 low - fewer than 100 (per square km)
50
97% of Egyptians live on 8% of the land.... High or low physiological density?
High
51
Provides insight into the efficiency of agricultural practices and the level of development in a region's agricultural sector
Agricultural density
52
farmers per unit of arable land
Agricultural density
53
what is a high/low agricultural density?
high - 100 per sq km low - less than 10 per sq km
54
Egypt has 2x the physiological density than Netherlands and 25x agricultural density. What does this suggest?
egypt has a less refined agricultural system and less arable land
55
Total population that can be adequately supported by the available resources on which that population subsists.
carrying capacity
56
Three things (not man-made) that affect carrying capacity, two man-made
Non: Livable space Arable land (food availability) Access to water Man: Agricultural technology Ability to import food
57
Which has a higher carrying capacity? Higher agricultural density? Mechanized farming vs small scale manual farming
Higher Carrying Capacity: mechanized farming Higher Agricultural Density: small-scale manual farming
