Geog 216 Midterm 2 Flashcards
what is demography
study of population characteristics important for considering future peoples needs
what is the demographic equation
r = b-d + i-e
what is the rate of natural increase
RNI = b-d
what is doubling time
time required for a population to double in size (70 divided by RNI)
what is the total fertility rate
average # of children a woman will have in child bearing years (15-44)
what is the replacement fertility rate
of children needed to have to replace ourselves
global number is 2.1
what is the infant mortality rate
of deaths that occur before age 1 for every 1000 live births, most progress in this
what is life expectancy, and what is the global average
of years expected to live at birth, average = 72
what were population drivers pre WW2 versus post WW2
pre ww2: increased food supply & basic living conditions/hygiene
post ww2: public health/medical advances & higher incomes
what is the demographic transition model and name the stages
a model of how the size of a population changes as a countries economy develops
1. pre industrial
2. transitional
3. industrial
4. post industrial
what is a population pyramid
population distribution by age & sex, can show increases, wars, famines, etc
what are pro natal and anti natal policies with examples
to manage fertility rates
pro natal: encourage children e.g. good childcare
anti natal: discourage children e.g. birth control access
decreasing population rates can be ___ or ___ (+ what is the slogan for anti natal)
coercive: one child policies
voluntary: educating women, birth control, etc
–> endogenous to devel process
“later, fewer, longer”
where is the biggest population growth and when is the world supposed to reach a stationary population
and how many ppl are added to the world per minute
in the developing world (asia & africa) and by 2100
158 to world, 90 in devel countries
does labor or capital move more freely
capital moves more freely than labor
who created + define push & pull factors
ravenstein created laws of migration (push & pull)
push factor (involuntary): unemployment, persecution, environmental
pull factors (voluntary): better job/weather
describe the wage differentials graph & what it means (and is it entirely true)
supply & demand curve meet at L or K
difference between L & K between countries is wage gap
migration leads to decrease in country A & increase in country B labor pools = convergence of wages w migration
–> more to do with industrialization
how many migrants are there, how many are worker migrants and how many are refugees
272 million migrants, 164 million migrant workers, 26 million refugees
is intl migration increasing? by what %? and what countries are primary senders / receivers
increasing from 2.5% 1995 to 3.5% 2019
senders: india, mexico, china
receivers: us, germany, saudi
what does the ‘stock of migration’ mean
of ppl in a country who have at one point migrated
what are the migration pathways and the % of migrants they contain
S to N: 40% –> most important
S to S: 33%
N to N: 22%
N to S: 5%
what is a refugee, what are refugee sending/receiving countries, and what pathway do they mainly us
displaced person crossing international border –> conflict is biggest driver
sending: syria, afghan, south sudan, myanmar, congo
receiving: pakistan, turkey, north sudan, uganda, germany
– S to S pathway, 81%
what are the drivers of north south migration REERS
R- return migration
E- economic opportunity
E- expansion of global companies
R- retirement migration
S- student migration
what are the 5 economic consequences of intl migration
- employment: need migrants to fill key job areas
- taxes & revenue: migrants bring money to govt
- brain drain/gain: sending loses educated ppl (haiti) but gains ideas sent back home
- well being: improve financially but not socially
- remittances
