What are the economic processes of immigration?

fewer workers will be available to contribute to pensions, health care, and other support that older people need

What are the effects of young populations?

-economic factors are the MAIN cause of migration -most migrants only move a SHORT distance -long-distance migrants are more likely to migrate to urban areas because they believe cities are more likely to have jobs than rural areas -most migration is rural to urban migration. Starting with the Industrial Revolution, which made fewer farm workers necessary, people have flocked from the countryside to the cities -MOST migration occurs through STEP migration -MOST migrants are YOUNGER ADULTS, people from age 20 to 45 with less established jobs -YOUNG MEN are more likely to migrate INTERNATIONALLY, as it poses a great risk, but WOMEN are more likely to migrate INTERNALLY, whether for work or to live with their husband's family -each migration flow produces a compensating counter-flow

What are the most common causes of maternal death in poor countries?

intervening obstacle: -in the past, it was distance (connects to distance decay model) -today, it is borders (ex: migrant needs a passport to legally emigrate from a country and a visa to legally immigrate to new country) (this relates to the time space compression model)
