Demographics

What is it? Demography is the study of population Why do people settle in certain areas? What lead to changes in settlement patterns? What trends can we see and why is it important?

Growing Population The world’s population is growing An estimated 7 Billion people 75% of all people live on less than 5% of Earth’s surface East Asia South Asia Southeast Asia Europe North America People live in a variety of places… URBAN= city areas RURAL= country areas SUBURBAN= residential areas outside of cities Over half the total population

Level of Development of Populations More developed countries have stable governments and economies (**Look at the countries in blue… Why are those places “developed”?) Less developed countries have unstable governments and economies

Population Growth Birth Rate or Fertility Rate: number of births per 1,000 people (Why would this be high?) Rate of natural increase: rate at which a population grows

Death Rate Death rate: number of deaths per 1,000 people Infant mortality rate: number of deaths of babies per 1,000 live births Why would these be high? Why would these be low?

Life expectancy Life expectancy= average biological years a citizen can expect to live. USA life expectancy is 77.9 years old. Factors influencing: healthcare, access to food and water, sanitation, and education.

Population distribution Population distribution– the pattern of human settlement. Humans live on roughly 1/3 of the earth’s land… Why so little?? Where do most people live?

Population Density Population Density- the concentration of people in an area Which areas of the world are the most densely populated?

Literacy Rate Literacy Rate: number of people in a population that can read and write Why would some countries have low LR?

More vs. Less Developed Demography Low birth rate, low death rate, low infant mortality rate, high life expectancy, and high literacy rate are all characteristics of which level of development? High birth rate, high death rate, high infant mortality rate, low life expectancy, low literacy rate are all characteristics of which level of development? CAN YOU EXPLAIN THESE FEATURES?? Discuss with a partner and be ready to share!

Demographics Journal What are demographics? What is the difference between a less developed and a more developed country? Give and explain specific examples. (For ex: birth rate, literacy rate, and death rate)

Factors Influencing Settlement Economic Factors – People move to areas of economic importance Jobs, transportation, education, etc.

Factors (cont) Social Factors – Affect a person’s lifestyle Religion, entertainment, etc.

Factors (cont) Political Factors – Affect a person’s sense of stability or freedom Escaping persecution, instability, etc.
