Unit 2 Population and Migration patterns and processes

Population geography → Geodemography

• doubling time:concept related to population growth. It refers to the number of years it takes for a population to double in size

• Total Fertility Rate (TFR): average number of children born to a woman over her entire life

• Crude birth rate (CBR): is the number of live births per 1,000 people in a given population per year → should take number of live births in a year divide to population and multiplied to 1000

• difference between crude birth rate and crude death rate is natural increase rate

what determines natural rate increase?

• economic development: quality of healthcare, employment opportunities…

• education: use of contraception, populations with high education level has low level of birth rate

• gender empowerment: status and opportunities for women

• cultural traditions

• public policy → one child policy

• to predict how much population will grow, population demographers use basic formula called c → total population +/- natural increase +/- net migration = balanced population.

Human migration

long term move of a person from one political jurisdiction to another

• people who leave their homelands to live in another country are said to be emigrate

• people who move into a country immigrate

reasons that cause people to migrate:

• political issues: oppressive regimes

• economic factors: job opportunities, cost of living. 20th century many European immigrated in east coast of America.

• environmental issues:for example Ethiopia, people migrate in search of more fertile land

• cultural issues: jews after WWII relocated in Israel.
