NIR plus migration rate
How is total population measured?
Why might an MDC have a higher crude death rate than an LDC?

wealthy, increased women's rights, widespread education, low birth and death rates, medical care
Explain the basic premises of Thomas Malthus' ideas

3- declining birth rate, low death rate
4- low birth and death rates
5- declining birth rate, low death rate
What are eugenic population policies?
governments favor some racial sectors over others
What is the purpose of an age-sex/population pyramid?
to show the demographic transition stage and the difference between male and female populations
How would a population pyramid of DT stage one look?
small, rectangular, few people
How would a population pyramid of DT stage two look?
large base, triangular, lots of young people, increasing number of older people
How would a population pyramid of DT stage three look?
triangular, declining number of young people, increasing number of older people
How would a population pyramid of DT stage four look?
rectangular, fairly even numbers of old and young people

Ravenstein's major laws:
most migrants move short distances, migrants who move further move to urban areas, urban residents are less migratory than rural ones, young adults are more likely to travel internationally than families, more men cross borders than women, a migration flow produces a counter-flow
Major characteristics of world migration:
poor to rich countries, men look for work then bring families, move to where they know people, more move to urban areas than to rural, main cause is money
