| Question | Answer |
|---|---|
| life expectancy | the amount of years a person is expected to life |
| crude birth rate (CBR) | the amount of live births per 1000 people. also an indicater of how ecenomicaly developed a country is |
| epidemiological transition | distinctive cause of death in each stage of demographical transition |
| arithmetic density | anount of people per anount of land area |
| medical revolution | medical technology invented in europe and north america that is diffused to poorer countries. this eliminated many traditional deaths by disease |
| doubling time | the number of years it takes for the population to double |
| pandemic | a disease that occurs over a wide area |
| crude death rate (CDR) | the amoutnt of deaths per 1000 people living. an indicater of how good the medical technology is |
| over population | too many people for the availible recourse |
| agricultural density | the number of farmers per amount of arable land |
| natural increase rate (NIR) | the percentage by wich the population increases by each year |
| dependency ratio | the number of people too young or old to work |
| infant mortality rate (IMR) | the amount of deaths for infants under a year of age per 1000 people |
| epidemiology | a branch of medical science concerned with diseases that affect large amounts of people |
| demographic transition | the change in a population from a high CDR, CBR and a low NIR to a low CDR, CBR, and low NIR |
| census | a complete enumeration of a populatioin |
| ecumene | a portion of earth that is permenently settled by humans |
| agricultural revolution | the time when humans first domesticated plants and animals and stopped hunting and gathering |
| demography | the study of populatioin characteristics |
| industrial revolution | the time when major improvements were made to industrial technology |
| zero population growth | the CBR equals the CDR near 0 and the NIR is 0% or close to it |
| sex ratio | the amount of males for every 1000 females |
| total firtility rate (TFR) | the average number of kids a woman will have while she can |
| physiological density | the number of people per arable land |
| population pyramid | a bargraph that shows the sex ratio and age groups |
| 2/3 of the population in the world live in which 4 groups? | south asia, south east asia, east asia, and europe |
| what is the difference between a cartogram and a regular map? | a cartogram shows you the size of a country using its population not its land area |
| what fraction of earth's population live in east asia? | 1/5 of the world lives in east asia |
| where do most people live in east asia and what to the y do for a living? | most live near the river valleys and pacific ocean and most farm for a living |
| what are some east asian countries? | japar, east china, the korean pininsula, and taiwan |
| what are some south asian countries? | indai, pakistan, bangladesh, shrilanka |
| what fraction of the world's population lives in south asia? | 1/5 |
| what are some south east asian countries? | java, philipines, sumatra, papua new guinea, boreno |
| what percent of europeans are armers? | 20% the rest live in cities. |
| what are the 4 sparsely populated regions acordint to the text book? | dry lands, wet lands, cold lands, high lands. |
| what does arithmetic density show? | how many people are trying to live in a certain amount of space |
| what does it mean of the physiological density is high? | the country has more pressure on it to provide its population with recourses |
| why is the agricultural density lower in MDC rather than LDC? | the MDC has better technology so less farmers are needed to farm |
| describe what happens on the demographic transition model in each of the 4 stages. | in stage 1 the CBR and CDR are high and the NIR is low. in stage 2, CDR drops, NIR rises and CBR is high. in stage 3 CBR drops and NIR decreases. instage 4 CBR and NIR are low and NIR is very low or non existent |
