Southeast Asia4. Western EuropeWhat similarities do they share in common?Is there a connection between population and climate zones?Sparsely Populated RegionsEcumene = portion of Earth’s surface occupied by permanent human settlementWhy would these regions by sparsely populated? Dry Lands –Wet Lands –Cold Lands –High Lands - Demography= study of populationPopulation density = measure of total population relative to land size; assumes an even distribution of population over landArithmetic population densityPhysiologic population densityEmphasizes general comparisons among countriesCan be very misleadingAgricultural Population Density-243840137160Which of the three types of population density measures (agricultural, physiological, or artihemtic) is this map describing? How do you know? How would this be different if it were showing arithmetic density? What do high densities mean here in terms of a country’s positional to feed itself into the future? What are problems with showing an arithmetic density by country scale map? Population Distribution - descriptions of locations on earth’s surface where individuals or groups (depending on scale) livePeople are not distributed evenly across world or within a countryOne-third of world lives in China and IndiaOften use dot mapsWorld Population Distribution & DensityHistorically people congregate where they can grow food in recent years – advances in technology and transportation have begun to change this pattern Why is complete, up-to-date population data crucial in any city, state, or country? Reliability of Population DataComplaints about 2000 US CensusMuch federal government funding depends on population dataIf population of disadvantaged group is undercounted, translates into loss of money for city governments that rely on federal funding to pay for social servicesBeing undercounted also translates into less government representation Number of congressional seats allotted to each state is based on census countSome estimates claim that the 2000 census undercounted US population by over 3.3 million peopleData on population growth rates, food availability, health conditions, and incomes are often informed estimates rather than actual countsUN, World Bank, Population Reference Bureau ................
