Statistics related to human population Learning Target • TIW – define key terms related to human population • SIC – compare and contrast developmental level of countries • IKW – I can match the definition to the terms with 100% accuracy Demography • Study of population (to write about or describe humans) – gender distribution, life expectancy, death rate, etc Birth Rate • Number of live births per year for every 1,000 people (births/1000/yr) Japan 8, US 13 Sierra Leone 37, Niger 46 Death Rate • # of deaths per year for every 1,000 people (deaths/1000/yr) Japan 9, US 8 Sierra Leone 11, Niger 12 Population Pyramid • Diagram of population by age and gender • Age structure diagram Infant Mortality Rate • Number of infant deaths per 1,000 live births per year (under 1 year old) Japan 2, US 6 Sierra Leone 73 Life Expectancy • Average # of years a person lives (sometimes separated by gender) • What factors influence life expectancy? • Why might women live longer than men, on average? Natural Increase / Growth Rate • Growth of a population in a year based only on death and birth rates Literacy Rate • Percentage of population that can read and write • How is it measured? Gross Domestic Product • Total of all goods and services produced by a country in a year Per Capita GDP • Average income per person for a country • Total gdp / # of ppl • Per capita = per head Qatar $102,000, US – $52,000 S.L. - $1,400, Niger $800 Population Density • Average # of ppl per square mile • Total population / area Urbanization Rate • % of the population living in the cities • urbanization – process of moving from the country to the city Review! • • • • • • % of the population that can read and write % of the population living in the city Avg years a person is expected to live # of infant deaths /1,000 in a year # of births / 1,000 in a year # of deaths / 1,000 in a year Infant mortality rate birth rate Life expectancy death rate Literacy rate urbanization rate • Urban – city areas (densely populated) • Rural – countryside (sparsely populated) Metropolitan Area • City and its surrounding area Subsistence Farming • Growing a variety of foods for family and village consumption Commercial Farming • Growing large quantities of one crop for profit Family Size • Do rich or poor countries have a larger family size, and why? Infrastructure • Basic structures and services that a government provides – i.e. roads, schools, utilities How did colonization impact infrastructure? • What did the Europeans build, and why? • What happened to it after the Europeans left?
